| SonicPotato | Good evening! | 00:25 |
| lotuspsychje | welcome SonicPotato | 00:25 |
| alschaapman | I'm having some trouble with kernel installation/upgrade on my system that has /boot formatted as VFAT | 00:31 |
| sedlav | Here's the setup: Ubuntu (fresh install) on /dev/sda and a previous Debian installation on /dev/sdb. GRUB automatically picks up on the old Debian installation. I have to manually go into BIOS and choose Ubuntu to boot. Is it safe to remove the Debian partiions on /dev/sdb without harming Ubuntu and GRUB? | 00:32 |
| oerheks | interesting, /boot as vfat? | 00:32 |
| alschaapman | I use systemd-boot and not grub, so the symlinks created by linux-update-symlinks are not useful to me -- i.e., I do not need /boot to be ext4. I symlinked /usr/bin/true at /usr/local/bin/linux-update-symlinks | 00:32 |
| Sven_vB | Trying to select a good display resolution on a focal live session. There seem to be 4 kinds of resolutions: {smaller,bigger} number first × preview showing as {landscape,portrait}. (I was surprised today to learned that those two criteria can be independent.) Is there any way to have the display settings tool display them grouped into four groups accordingly? | 00:33 |
| alschaapman | The problem is that dpkg configure does *not* work when the postinstallation hook for the kernel package is executed by apt, I suspect because apt executes these hooks as some system user that doesn't have /usr/local/bin in $PATH | 00:33 |
| alschaapman | dpkg --configure linux-image-blahblahblah works fine | 00:33 |
| alschaapman | Is there a way I can fix this? | 00:33 |
| alschaapman | To be clear: configuring the package *fails* when apt is used, but *doesn't* fail with dpkg --configure | 00:36 |
| alschaapman | I don't want to take the route of symlinking /usr/bin/true at /usr/bin/linux-update-symlinks. The symlink would get overwritten whenever linux-base is upgraded, I think | 00:37 |
| ubuntuuser | eh I don't need it | 00:37 |
| ubuntuuser | seems hard | 00:38 |
| Sven_vB | alschaapman, I had similar problems and it was a real pain to have /boot be FAT. maybe we can find ways to work around it? why do you need it to be FAT? | 00:38 |
| alschaapman | Sven_vB: I'm using systemd-boot. The kernels and initrds have to be on a filesystem that's accessible by the firmware | 00:38 |
| Sven_vB | alschaapman, oh ic | 00:39 |
| alschaapman | This actually shouldn't be too difficult, necessarily -- since dpkg --configure works, it's clear that (probably) the only problem is the package's postinst hook is getting executed in an environment where $PATH does not contain /usr/local/bin, *when using apt* | 00:40 |
| Sven_vB | alschaapman, so if that's a limitation to systemd-boot, what made you choose it? | 00:40 |
| alschaapman | Sven_vB: systemd-boot is awesome. GRUB is terrible. | 00:40 |
| Sven_vB | alschaapman, I wouldn't consider it too awesome if it can't boot kernels from another partition. :D | 00:41 |
| Sven_vB | alschaapman, but I wonder, usually the systemd people make stuff better and add cool features, not omit them | 00:41 |
| alschaapman | I imagine they have a good reason why systemd-boot doesn't load its own filesystem drivers, as GRUB probably does | 00:42 |
| alschaapman | Anyway there's like a handful of things that even need to go in /boot *at all* | 00:42 |
| alschaapman | It's actually an unnecessary problem to have, putting constraints on what filesystem can be used. | 00:43 |
| alschaapman | Also this isn't ultimately going to be the case for my setup when I'm done with everything, but systemd-boot was originally designed to load kernels and initrds from the EFI system partition, which is a perfectly sensible place to put them | 00:44 |
| Sven_vB | yeah Ubuntu still has lots of annoying problems that should be solved, but at least it has become a lot better over the years. :-) | 00:44 |
| alschaapman | ESP can be limited in size, though, so I'm actually using an Extended Boot Loader Partition as defined in the Boot Loader Spec as a shared filesystem for all my kernels | 00:44 |
| alschaapman | I have Arch, Red Hat, and Ubuntu installed and all their kernels go in that vfat partition | 00:45 |
| Sven_vB | indeed. one possible work-around would be to make something that triggers on initramfs updates, waits until the situation has settled, then copies the new files over to the ESP. | 00:45 |
| alschaapman | The kernel package hooks already do all the work there, including the generation of the initrd | 00:46 |
| Sven_vB | well, then let's go find out what user is being used or why stuff fails. I'll see if I can find the error message again | 00:46 |
| alschaapman | I'm really about 90% there. What is needed is to figure out how $PATH can include /usr/local/bin when apt invokes that postinstall hook, which is where linux-update-symlinks is called from | 00:46 |
| Sven_vB | oooooh now I see why you do all that. it's much easier. use dpkg-divert to declare that from now on, you want to manage /usr/bin/linux-update-symlinks yourself and dpkg shall not interfere. then symlink it to true. | 00:49 |
| alschaapman | Sven_vB: I don't really know what that means or how to do that | 00:50 |
| strywgr | my usb external hdd is not showing up | 00:50 |
| alschaapman | I'm used to doing all my package management with pacman and when I'm using something that's not Arch honestly I *really* miss it lol | 00:51 |
| Sven_vB | alschaapman, yeah I have to read man dpkg-divert myself when I need it, it's too rare to remember. | 00:51 |
| alschaapman | I don't think this will help me | 00:52 |
| Sven_vB | why not? "dpkg-divert --add --rename /usr/bin/linux-update-symlinks" and from then, you can safely put your own stuff at /usr/bin/linux-update-symlinks, e.g. a symlink to /bin/true | 00:53 |
| alschaapman | Oh, I see what you mean | 00:53 |
| alschaapman | I thought you were trying to say that I should divert the symlinks, which are not owned by the package | 00:54 |
| alschaapman | Here's the script from the most recent linux-image-generic package: http://ix.io/2qhf | 00:54 |
| alschaapman | (That's the postinst script. linux-update-symlinks gets invoked on line 50) | 00:54 |
| Sven_vB | it will probably just work. | 00:55 |
| alschaapman | I think you're right -- seems like diverting /usr/bin/linux-update-symlinks from the linux-base package would stop my symlink to /usr/bin/true from being overwritten. I'm just not totally sure if that's the best way yet | 00:56 |
| alschaapman | Is there a reason these package scripts are executed with a modified environment when they're run by apt as opposed to dpkg, and is there definitely no way (or no way that would be a good idea) to change the environment so /usr/local/bin is in $PATH? | 00:57 |
| Sven_vB | it's the easiest I can think of. you can undo the diversion at any time once you discover a better method. | 00:57 |
| Kamilion | how do i get around this when trying to boot focal? error: not xen image. | 00:58 |
| Sven_vB | you could modify the script to dump the environment to a file, maybe you can find clues in there. it might even be that PATH has all the dirs just in a different order. | 00:58 |
| Sven_vB | alschaapman, ^ | 00:58 |
| alschaapman | How would I do that? The script is part of the package itself | 00:59 |
| Sven_vB | Kamilion, what flavor and version of focal are you trying to boot, and on what kind of machine? | 00:59 |
| alschaapman | I could create a package with the Arch Build System no problem, but I've never authored a .deb | 00:59 |
| Kamilion | focal, on focal. | 00:59 |
| Sven_vB | alschaapman, sudo + texteditor should work. it's just a temporary change for research. | 00:59 |
| Kamilion | focal's xen-hypervisor-amd64 (4.11), running any-spin-at-all, or upgrades from 18.04. | 01:01 |
| Sven_vB | alschaapman, or you could even make /usr/bin/linux-update-symlinks a bash script that dumps the env :) then you wouldn't even need to modify the postinstall script | 01:01 |
| alschaapman | Sven_vB: That's just what I was thinking, yeah | 01:01 |
| Kamilion | trying to load any 5.x kernel bails in grub with "error: not xen image." | 01:02 |
| Sven_vB | alschaapman, you could even put a network shell there, and inspect the circumstances live, trying to find clues. | 01:02 |
| Kamilion | upgrading a guest install of 18.04 via mini.iso with do-release-upgrade -d to focal succeeds in updating all the packages, rebooting to the new 5.4 kernel fails, but it boots with the last 4.15 from bionic. | 01:03 |
| Kamilion | i can respin isos if only i can find a freaking kernel image xen will boot | 01:04 |
| Kamilion | i can't even get any of the cloud-image variants to boot. it's maddening. | 01:05 |
| ForeverNoob[m] | hello, I basically followed this guide: https://mullvad.net/en/help/easy-wireguard-mullvad-setup-linux/ ... and then did "sudo wg-quick up mullvad-se4" | 01:07 |
| Kamilion | tried several copies of pvgrub2 as well; including updating my own script from 4.9 to 4.11: https://github.com/kamilion/kamikazi-core/blob/master/buildscripts/bionic/40-build-pvgrub2-image.sh | 01:08 |
| ForeverNoob[m] | but it then says: "RTNETLINK answers: Operation not supported" and "Unable to access interface: Protocol not supported" | 01:08 |
| sarnold | ForeverNoob[m]: what release are you using? those ppa instructions won't be necessary on focal, you should use the built-in wireguard instead | 01:09 |
| ForeverNoob[m] | now I found this page (https://www.ivpn.net/knowledgebase/241/Linux---WireGuard---RTNETLINK-answers-Operation-not-supported.html) telling me that I should "sudo modprobe wireguard" first, which I did, but then it said: modprobe: FATAL: Module wireguard not found in directory /lib/modules/4.15.0-101-lowlatency | 01:09 |
| ForeverNoob[m] | sarnold: 18.04 | 01:09 |
| ForeverNoob[m] | so I guess my question is... if modprobe is giving me that error, does it make any difference if I reboot or is that pointless? | 01:10 |
| ForeverNoob[m] | I have quite a lot of running stuff open and I'd rather not reboot if I don't have to. | 01:11 |
| sarnold | ForeverNoob[m]: hmm, there's a chance that ppa may not support the lowlatency kernel.. | 01:11 |
| sarnold | ForeverNoob[m]: I doubt a reboot would helkp | 01:11 |
| ForeverNoob[m] | darn | 01:12 |
| ForeverNoob[m] | I'll have to go with a HWE kernel then | 01:13 |
| ForeverNoob[m] | (and thus still have to reboot :p) | 01:13 |
| oerheks | hwe +1 | 01:13 |
| p0wder | how do i remove the popup that says updates available on ubuntu 20.04 | 01:14 |
| sarnold | ForeverNoob[m]: yeah, I think that's probably wehat is necessary. at least then you don't have to use a ppa or dkms, which is nice | 01:14 |
| p0wder | i switched check for updates to never, and i uninstall unattended-upgrades, and disabled the unattended-upgrades service | 01:15 |
| p0wder | packagekitd maybe? | 01:15 |
| p0wder | you would think auto check never would be enough.. :\ | 01:16 |
| sarnold | p0wder: probably not; check systemctl list-units '*apt*' | 01:16 |
| ForeverNoob[m] | oerheks: so in my case I'll have to do... "sudo apt install --install-recommends linux-lowlatency-hwe-18.04 xserver-xorg-hwe-18.04" | 01:17 |
| ForeverNoob[m] | ? | 01:17 |
| sarnold | ForeverNoob[m]: hmm, I *think* you can do just the kernel and skip X | 01:18 |
| p0wder | i found theses 2- apt-daily-upgrade.timer, and apt-daily.timer | 01:18 |
| ForeverNoob[m] | sarnold: I got that info from https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Desktop | 01:18 |
| sarnold | p0wder: are they enabled or disabled? | 01:19 |
| p0wder | i think so, it says loaded and active for both | 01:19 |
| === zbenjamin is now known as Guest47484 | ||
| === zbenjamin_ is now known as zbenjamin | ||
| sarnold | p0wder: I rarely work with systemd timers, but I bet you can just disable those | 01:20 |
| oerheks | .. that ppa may not support the lowlatency kernel.., but it likes HWE. | 01:20 |
| p0wder | ill give it a shot.. thanks! | 01:21 |
| ForeverNoob[m] | oh no... apt show linux-lowlatency-hwe-18.04 tells me the kernel is 5.3.0.61.114 ... which means it doesn't have the WireGuard in it. WireGuard is on 5.6 and up right? | 01:21 |
| oerheks | .. you have that ppa?¿ | 01:22 |
| oerheks | i told you yesterday, it will give the same | 01:22 |
| ForeverNoob[m] | what PPA? | 01:23 |
| oerheks | interesting. | 01:23 |
| ForeverNoob[m] | I don't see any PPA mentioned here: https://wiki.ubuntu.com/Kernel/LTSEnablementStack | 01:24 |
| sarnold | $ apt-file show linux-modules-5.3.0-61-lowlatency | grep wireguard | 01:25 |
| sarnold | linux-modules-5.3.0-61-lowlatency: /lib/modules/5.3.0-61-lowlatency/kernel/wireguard/wireguard.ko | 01:25 |
| sarnold | ForeverNoob[m]: ^^ pretty sure no ppa is needed | 01:25 |
| ForeverNoob[m] | oh huh, so it's backported then! awesome! | 01:25 |
| sarnold | yeah, the wireguard author put in a fair amount of effort to provide backports for us for focal, and iirc for a debian kernel too | 01:26 |
| ForeverNoob[m] | zx2c4... you da man! | 01:27 |
| ForeverNoob[m] | aight, gonna reboot... fingers crossed! | 01:34 |
| sarnold | woot | 01:34 |
| ForeverNoob[m] | it has workened! | 01:49 |
| ForeverNoob[m] | (I can't connect to my local devices, but still... progress! :D) | 01:50 |
| sarnold | ForeverNoob[m]: yay! progress :D | 01:53 |
| ForeverNoob[m] | \o/ | 01:54 |
| ForeverNoob[m] | thanks everyone so far :) | 01:55 |
| ForeverNoob[m] | I guess it's one of the iptables rules: | 01:55 |
| ForeverNoob[m] | PostUp = iptables -I OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -I OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT | 01:55 |
| ForeverNoob[m] | PreDown = iptables -D OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -D OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT | 01:55 |
| ForeverNoob[m] | so I kinda sorta have the culprit located | 01:56 |
| ForeverNoob[m] | and it miiight just be "--dst-type LOCAL -j REJECT" | 01:56 |
| sarnold | it's crazy enough it just. might. work. | 01:57 |
| strywgr | does this channel also helps for Lubuntu? | 02:06 |
| sarnold | strywgr: it's worth a try, but if it's specifically about part of the lubuntu desktop environment rather than a "standard" tool you may do better in #lubuntu | 02:12 |
| strywgr | i tried thr. Ive a external usb hdd which is not showing up on lubuntu. It works fine on another laptop having windows 7. Ive tried commands found on various help blogs, no luck. | 02:13 |

| aswd | I discovered snap only today. Looks cool but I'm a bit confused now. When should I use snap versus apt-get? Both serves the same purpose to me | 02:58 |
| addyess | aswd: snap if you can. it runs the app in a sandbox that cannot affect other applications without you granting specific permissions per app. | 02:59 |
| aswd | addyess: so, no dependencies problem? | 03:00 |
| addyess | all the dependencies are wrapped in the snap. its kinda like a little container that has all the deps built in | 03:00 |
| aswd | addyess: sounds good for deployment but wouldn't this lead to bloated software that takes a lot of space? | 03:01 |
| addyess | it makes it for developers to know exactly which versions of things are being used | 03:01 |
| addyess | it does take more space... | 03:01 |
| addyess | that's the trade off | 03:01 |
| aswd | addyess: substantially more space or extra space that can be ignored, from your experience? | 03:01 |
| oerheks | if you keep 3 versions of a large snap, yes | 03:02 |
| addyess | i mean, i've got like a 1TB SSD--- i don't miss 50MB here or there | 03:02 |
| oerheks | but for security and fast updates, snaps are the new ppa | 03:02 |
| aswd | oerheks: hmm ... why would people keep 3 versions of same software? I always use latest one. Will the older version be retained using snap? I thought updated one should simply replace older one | 03:03 |
| addyess | canonical does currently maintain the only store... but i think their going forward path is to push more towards snaps and away from apt | 03:03 |
| oerheks | no, you keep 2-3 versions to roll back. | 03:03 |
| oerheks | !snap | 03:03 |
| ubottu | Snaps are containerised software packages similar to flatpaks or appimage. For more info, see https://snapcraft.io | 03:03 |
| aswd | oerheks: why is snap more secure? isn't it the same software as the one installed by apt-get? | 03:04 |
| addyess | b/c program 1 with root permissions cannot overwrite program 2 file system | 03:04 |
| aswd | oerheks: so, keeping 2-3 versions applies for all software installed by snap? I don't think apt-get does this | 03:04 |
| oerheks | some software are no longer available with apt-get, more secure by automatic update before 1st start/day | 03:05 |
| addyess | two apps installed today with apt can both write to /etc/something/something b/c root installed them | 03:05 |
| oerheks | when you remove a snap, no clutter in your system. | 03:06 |
| addyess | but the snaps see two different /etc/something/somethings when they run and view the filesystem | 03:06 |
| addyess | ^^ also true | 03:06 |
| oerheks | and looking at wine 32 bit.. a good alternative | 03:06 |
| * addyess is out.... | 03:07 | |
| aswd | What is the snap version of apt-get update/upgrade if I want to update all packages to latest? | 03:07 |
| oerheks | refresh | 03:08 |
| sarnold | aswd: when you install a deb package, the maintainer scripts get to run with full root privileges; snap package maintainer scripts run in the same sandbox that is used for the application | 03:12 |
| aswd | sarnold: check my understanding. If my Ubuntu is fully made of snap software, it is very secure OS because no malware can touch sensitive parts, correct? | 03:15 |
| sarnold | aswd: that's too broad a statement | 03:16 |
| sarnold | aswd: snap's sandboxes are very helpful things, but what is allowed for them to do, read, write, etc, may not line up with what you'd like to prevent them from doing, or allow them to do, etc | 03:17 |
| sarnold | aswd: and snap applications can still do the same X11 tricks that non-snap-applications can do https://mjg59.dreamwidth.org/42320.html | 03:18 |
| oerheks | snaps come with a permission option, like this , multipass https://imgur.com/gallery/t0I0c8L | 03:19 |
| aswd | Is it true that as you install more snap-apps, your shutdown time increases drastically | 03:50 |

| dodocrypto | is there anyway where we can download update from https ? | 08:00 |
| dodocrypto | i am using lubuntu | 08:00 |
| dodocrypto | but the package is missing it said when i update | 08:00 |
| byroniac | CoDeAmRo sorry I don't know | 08:01 |
| oerheks | what package exactly? did you run sudo apt update before running upgrade? | 08:01 |
| oerheks | byroniac, we don't do piracy, glad he left | 08:02 |
| oerheks | :-P | 08:02 |
| byroniac | I didn't even know what he was talking about anyways | 08:02 |
| byroniac | no desire to do any kind of piracy | 08:03 |
| PeGaSuS | dodocrypto: the exact error message would be helpful to know what you're missing. also, try to do `apt update` before `apt dist-upgrade` as suggested by oerheks | 08:08 |
| dodocrypto | yeah oerheks | 08:08 |
| dodocrypto | i run it and even change main server to mirror and to main | 08:08 |
| dodocrypto | is crazy slow to download from main server | 08:09 |

| dodocrypto | man this is so annoying | 08:20 |
| dodocrypto | i was on main server | 08:20 |
| byroniac | @dodocrypto I don't know how to fix your problem but what about downloading the packages you need directly? e.g., https://ubuntu.pkgs.org/18.04/ubuntu-updates-main-amd64/libpython3.6-minimal_3.6.9-1~18.04ubuntu1_amd64.deb.html | 08:23 |
| oerheks | seriously, python3.6? | 08:24 |
| byroniac | although you need the i386 version and there is a link to it on that page | 08:26 |
| dodocrypto | yeah | 08:29 |
| dodocrypto | how to install dependancies of the package | 08:29 |
| dodocrypto | is there anyway | 08:30 |
| dodocrypto | to install manually i mean | 08:30 |
| dodocrypto | with out using apt install ./ | 08:30 |
| dodocrypto | it direct me to download again which going to be failed | 08:30 |
| dodocrypto | wuhu thank you guys | 08:32 |
| dodocrypto | finally i can upgrade all packages | 08:32 |
| dodocrypto | mannnn | 08:32 |
| dodocrypto | can't believed why apt can't download the packages | 08:33 |
| CameronBraid | Hi, I have a ubuntu server that is having a strange performance issue. The typical load for this server is around 7 (has 48 ht cores) yet when I do a `cp -r` for a folder that is 30 gig, the load spirals up to over 200 and sometimes I have to reboot since everything locks up | 08:38 |
| byroniac | @dodocrypto once you download a .deb you can install it with "sudo dpkg -i filename.deb" | 08:44 |
| byroniac | I don't know why you can't download... possible network issues | 08:44 |
| tomreyn | CameronBraid: so disk i/o issues. this can be for a couple reasons. anything related in dmesg / journalctl -k / journalctl -p3 -b #? | 08:50 |
| tomreyn | CameronBraid: which server hardware, storage controllers, storage media? | 08:50 |
| * dodocrypto brb restarting | 08:52 | |
| CameronBraid | tomreyn no io errors are happening and nothing in dmesg or journalctl that jump out at me. I noticed that I if I run `echo 1 > /proc/sys/vm/drop_caches` it relieves it for a bit. The server has 128g ram, and moire than 28Gig free | 09:00 |
| CameronBraid | tomreyn its 2 * ssd raid1 using a hardware raid controller | 09:01 |
| tomreyn | CameronBraid: does trim work (regular runs configured and successfully applied?) on its file systems? | 09:02 |
| tomreyn | which raid controller, which mainboard, which ssds, which cpu? | 09:03 |
| CameronBraid | tomreyn its a brand new system, Supermicro | 09:05 |
| tomreyn | would you like assistence with determining these details i asked about? | 09:06 |
| CameronBraid | tomreyn raid is megaraid MR9267-8i | 09:06 |
| CameronBraid | tomreyn sorry, just takes me a bit of time to remember all the commands : | 09:06 |
| CameronBraid | tomreyn Intel(R) Xeon(R) CPU E5-2690 v3 @ 2.60GHz * 2 | 09:07 |
| CameronBraid | tomreyn its a samsung disk, forgot the command to get it | 09:08 |
| tomreyn | CameronBraid: ls -l /dev/disk/by-id/ | 09:09 |
| CameronBraid | tomreyn motherboard Supermicro X10DRL-i | 09:10 |
| tomreyn | CameronBraid: which ubuntu release is it? nc termbin.com 9999 < <(lsb_release -ds;cat /proc/{version,cmdline};echo "Session: $XDG_CURRENT_DESKTOP ($XDG_SESSION_TYPE)";echo Shell: $SHELL) | 09:10 |
| tomreyn | actually just lsb_release -ds is enough | 09:10 |
| CameronBraid | tomreyn Samsung SSD 860 EVO 1TB | 09:11 |
| CameronBraid | Ubuntu 18.04.4 LTS | 09:11 |
| tomreyn | CameronBraid: journalctl --since 2020-06-01 | grep 'fstrim\[' | nc termbin.com 9999 | 09:12 |
| CameronBraid | tomreyn `journalctl --since 2020-06-01 | grep 'fstrim\[' ` is empty | 09:13 |
| tomreyn | CameronBraid: what's the output of: sudo sync && sudo fstrim -v / && sudo fstrim -v / | 09:13 |
| CameronBraid | tomreyn fstrim: /: the discard operation is not supported | 09:14 |
| tomreyn | hmm, which block layers do you have there? hardware raid-1, then the ssds, then partition tables, then ..? | 09:15 |
| tomreyn | *block device layers | 09:16 |
| CameronBraid | that's it.. hw raid1 of 2*ssd, partition table, ext4 fs | 09:16 |
| tomreyn | so the raid must block or just not expose trim | 09:17 |
| CameronBraid | lshw -short -C disk : /0/100/2/0/2.0.0 /dev/sda disk 999GB MR9267-8i | 09:17 |
| CameronBraid | fstab. :/dev/disk/by-uuid/e5475145-e868-4d44-ad90-9762400d93d7 / ext4 | 09:17 |
| CameronBraid | tomreyn I have to go for a bit, thanks for your help so far, will be back in 1/2 hour or so if you are still available to help | 09:19 |
| tomreyn | so it looks like the raid controller does not enable the operating system to trigger TRIM, maybe discards can work, but that's not ideal. | 09:20 |
| tomreyn | CameronBraid: if i was in your shoes, i'd try to get a better understanding of whether this rais controller (and the firmware you have on it now, as well as newer firmwares) support passing through TRIM commands from the OS. | 09:41 |
| tomreyn | in a RAID-1 configuration (no parity), this should be possible. | 09:42 |
| CameronBraid | tomreyn: how does not supporting trim cause the load issue I am having ? | 09:43 |
| tomreyn | if you can't find out or find out that it can't support it, look into whether you can choose to only assign part of the SSDs to the RAID, leaving 5% capacity unassigned. | 09:43 |
| tomreyn | CameronBraid: my theory is that sustained writes to the storage are slowed down because the ssd's can't carry out sustained writes after their cache runs full, and emptying the cache takes longer than it would if trim or unpartitioned space was available, easing the stress on the ssd's firmware. | 09:45 |
| tomreyn | there could be other reasons, of course. but we've already seen that fstrim doesn't work on your system. and i assume you have the full disks assigned to the raid-1, so i guess these consumer disks are under much stress. | 09:47 |
| tomreyn | https://serverfault.com/questions/776564/what-is-the-current-state-2016-of-ssds-in-raid touches some of this | 09:47 |
| tomreyn | also check for ssd firmware upgrades (though from what i remember there are none for 860 evos) | 09:49 |
| CameronBraid | the raid controller identifies the device as 999GB, and the /dev/sda is 931G so I presume there is already some space spaed | 09:51 |
| CameronBraid | fyi I also get this same issue with an iscsi device (nimble) connected over 10gb ethetnet | 09:52 |
| CameronBraid | the stress seems to come when the kernel has maxed by filling the free ram with page cache (if that's the correct term) | 09:53 |
| CameronBraid | which is why drop_caches makes it work again | 09:53 |
| tomreyn | are you using the HWE kernel or GA? | 09:57 |
| CameronBraid | Linux node01 4.15.0-106-generic #107-Ubuntu SMP Thu Jun 4 11:27:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux | 09:58 |
| CameronBraid | does that answer it ? I dont know what HWE or GA mean | 09:59 |
| tomreyn | so GA. my bets are still on the storage controller / disk configuration cuasing the problems, but switching to the HWE kernel should be easy if it can be out of production for a bit. | 09:59 |
| tomreyn | !HWE | 09:59 |
| ubottu | The Ubuntu LTS enablement stacks provide newer kernel and X support for existing LTS releases, see https://wiki.ubuntu.com/Kernel/LTSEnablementStack | 09:59 |
| lotus|NUC | tomreyn: i had a few 860 evo's that needed firmware and some not recently, think it depends how long it layed in the shops stock? | 09:59 |
| tomreyn | 'GA' would be 'general availability', the kernel version 18.04.0 came with | 09:59 |
| CameronBraid | so, it means that you get a newer kernel in 18.04 | 10:00 |
| tomreyn | lotus|NUC: probably, yes. so it depends on which version was installed originally. if the old one, an upgrade is available, if it already had the new one, then not. | 10:00 |
| lotus|NUC | yeah | 10:00 |
| tomreyn | CameronBraid: you can choose between two 'paths' at any time during the 18.04 support life cycle. the "keep me updated" one would be HWE (where the kernel version increases over time), the "always keep the same version (but with backported fixes)" would be GA. | 10:02 |
| CameronBraid | ok, so looks like its 5.3.0.61.114 kernel in HWE.. it might be worth a try | 10:03 |
| CameronBraid | and since its just a package it can easily be reverted right ? | 10:03 |
| tomreyn | you'd install linux-generic-hwe-18.04, which would cause both GA and HWE to be installed, selectable from grub menu | 10:03 |
| CameronBraid | cool | 10:04 |
| CameronBraid | alright, youve given me some hope, something to try after hours tonight :) | 10:04 |
| tomreyn | yes, you could pirge andthyin *hwe-18.04 and reboot to get back to where you'Re now | 10:04 |
| tomreyn | *pUrge | 10:04 |
| tomreyn | *anything ;) | 10:04 |
| CameronBraid | I wanted a newer kernel for the fixes to groups cpu scheduling in docker anyway.. so this might be the thing to do anyway | 10:05 |
| CameronBraid | sed /groups/cgroups | 10:05 |
| tomreyn | lotus|NUC: keep in mind that it may be more complex than this: samsung may also choose not to install newer firmware on older ssds based on e.g. drive serial number. | 10:06 |
| lotus|NUC | tomreyn: yeah thats possible | 10:06 |
| tomreyn | CameronBraid: might be nice to have, 4.15 is getting a little old now. | 10:07 |
| CameronBraid | yeah, in the long term I would upgrade to 20.04, its just when I provisioned the server kubespray didn't support 20.04 | 10:07 |
| tomreyn | CameronBraid: latest GA kernel is linux-image-4.15.0-108-generic, you said it was running -106, so you may want to just try installing updates first of all. | 10:09 |
| CameronBraid | tomreyn: ok, thanks.. i really appreciate your help. | 10:10 |
| tomreyn | you're welcome | 10:10 |
| CameronBraid | i'm off for a bit, will come back online when I do the upgrade later.. chat then | 10:10 |
| tomreyn | if i'll be around, sure. :) see you, good luck | 10:10 |
| CameronBraid | ciao | 10:10 |
| apus | hi, is it possible to tell apt-get to install all (additional) packages i'd specify by for example "apt-get install r-cran-*" , AND ignore all packages that are in any way in conflict with previously (successfully) installed related packages, so disabling any removal, downgrade, etc. ? at the moment it tells me there are dependency conflicts and i don't want to debug this - there is no real reason for it, i'm happy to exclude any packages taht cause | 10:26 |
| apus | problems. | 10:26 |
| tomreyn | if there are dependency conflicts then your apt configuration is bad | 10:28 |
| oerheks | "To be able to use R 4.0, you will have to delete everything about the previous R version" https://rtask.thinkr.fr/installation-of-r-4-0-on-ubuntu-20-04-lts-and-tips-for-spatial-packages/ | 10:28 |
| apus | tomreyn: the problem is that not all R packages are "up-to-date", because this is ubuntu 18.04 (yes i know). so i make sure the basics i need work, by choosing those packages that work together. now i'd like to find an "easy" way to install any additional compatible packages. | 10:30 |
| amuro | IS there a way to install pdfjam in ubuntu 20.04??? | 10:33 |
| oerheks | apus, there are some 500 additional r-cran-* packages, which one is not up2date? | 10:34 |
| lotus|NUC | amuro: choose another alternate from the ubuntu repos/snaps? | 10:34 |
| tomreyn | apus: does oerheks' link not help there? | 10:34 |
| amuro | lotus|NUC: how? | 10:35 |
| oerheks | amuro, no, you asked before, pdfjam is obsolete, precise as last one? | 10:35 |
| cluelessperson | So I'm just downloading files from mega.nz on ubuntu chromium | 10:35 |
| cluelessperson | and my system is just slowed to a crawl in general | 10:35 |
| amuro | why obsolete? | 10:36 |
| tomreyn | cluelessperson: the way this download site works it has to store the entire download in ram before it can write it to disk. if you're short of ram, it'd have to start swapping ram to disk, which can be slow. | 10:37 |
| oerheks | amuro, dead, no longer maintained? | 10:37 |
| oerheks | https://launchpad.net/ubuntu/+source/pdfjam/2.05-2 | 10:37 |
| cluelessperson | tomreyn, Well, considering this download 60GB, I doubt it's fitting in ram or on swap | 10:37 |
| tomreyn | cluelessperson: dpends on how much of that you have, i guess. | 10:38 |
| amuro | oerheks: its not dead | 10:38 |
| cluelessperson | tomreyn, still, my system shouldn't slow to a crawl so easily | 10:38 |
| cluelessperson | I think linux/ubuntu has some fundamental issues | 10:39 |
| amuro | I found it in the texlive-extra-utils package, nevermind | 10:39 |
| lotus|NUC | cluelessperson: slow system; tweak it more? | 10:39 |
| cluelessperson | lotus|NUC, tweak what? | 10:39 |
| lotus|NUC | cluelessperson: whats going slow? | 10:40 |
| cluelessperson | lotus|NUC, the fact that ubuntu allows chrome to basically take up 100% cpu to the point nothing else responds? | 10:40 |
| * cluelessperson tries nicing gnome-shell | 10:40 | |
| tomreyn | amuro: install texlive-extra-utils https://packages.ubuntu.com/focal/all/texlive-extra-utils/filelist | 10:40 |
| tomreyn | oh i'm late | 10:40 |
| amuro | thx | 10:42 |
| apus | oerheks: i'll check the link again. r-base-core provides r-api, r-base-core is installed with version 3.6.3, the following packages show dependencies on r-api-3.4: r-cran-funitroots, -gmaps, -its, -mfilter, -nws, -pwt8, -rsprng, then r-cran-haplo.stats has version conflict with r-base-core, libproj13 >= 4.9.0 is not installable, and a few other things. | 10:42 |

| lotus|NUC | amuro: packages come and go in ubuntu | 10:50 |
| tomreyn | amuro: yes, in old ubuntu releases there was a pdfjam virtual package which depended on texlive-extra-utils. maybe in even earlier releases this was a real package, not just virtual | 10:51 |
| amuro | Why such a useful software be obsolete? | 10:51 |
| amuro | I am just wondering | 10:51 |
| lotus|NUC | amuro: wich feature interests you exactly on pdfjam? maybe the volunteers know a nice alternate? | 10:51 |
| oerheks | wait, you found the package, .. | 10:52 |
| amuro | lotus|NUC: for example merging pdfs, merging 4 pages into 1 page, etc | 10:53 |
| lotus|NUC | amuro: did you try out inkscape yet? | 10:53 |
| amuro | lotus|NUC: But sometimes I want to do it in like 100s of pdf in a folder. | 10:54 |
| amuro | its easier with pdfjam or pdftk | 10:54 |
| amuro | is inkscape for creating vector graphics | 10:55 |
| amuro | I dont know how to use inkscape | 10:55 |
| lotus|NUC | amuro: try a few from here: https://askubuntu.com/questions/2799/how-to-merge-several-pdf-files | 10:55 |
| tomreyn | ChrisWarrick: i assume you need to ubuntu-bug nvidia-graphics-drivers-390 | 10:56 |
| amuro | lotus|NUC: but pdftk doesn't do multiple input pages into one output page | 10:57 |
| ChrisWarrick | tomreyn: I would expect the bug to be in whatever does the install, not in the deriver itself | 10:57 |
| ChrisWarrick | tomreyn: is the instaler supposed/expected to install the right version though? or just sees nvidia and installs the latest? | 10:57 |
| tomreyn | ChrisWarrick: the driver binary package defines which hardware (PCI IDs) it is compatible with (see the "Modaliases:" in "apt show nvidia-driver-390") | 10:58 |
| tomreyn | ChrisWarrick: and then "ubuntu-drivers" installs the latest that's compatible by default, i think | 10:59 |
| oerheks | ubuntu-drivers autoinstall gives the right driver | 10:59 |
| tomreyn | ChrisWarrick seems to have pointed out that's nto the case for his hardware | 11:00 |
| ComputerChic | So who has a nuc? | 11:00 |
| tomreyn | !discuss | ComputerChic | 11:00 |
| ubottu | ComputerChic: Want to talk about Ubuntu, but don't have a support question? /join #ubuntu-discuss for non-support Ubuntu discussion, or try #ubuntu-offtopic for general chat. Thanks! | 11:00 |
| tomreyn | unless you have a support question regarding ubuntu on some nuc? | 11:01 |
| oerheks | tons of nucs out there, polling is useless. | 11:01 |
| tomreyn | amuro: why don't you just use the pdfjam that's in texlive-extra-utils? | 11:02 |
| amuro | tomreyn: I did | 11:03 |
| amuro | tomreyn: But then I have to install other stuff that I dont need. It's like 100 MB instead of like 10 MB | 11:03 |
| tomreyn | oh, tough. | 11:04 |
| tomreyn | so you had to juggle floppy disks? | 11:04 |
| amuro | tomreyn: sort of haha | 11:04 |
| tomreyn | maybe you need to rethink your storage concept | 11:04 |
| amuro | maybe | 11:05 |

| BluesKaj | 'Morning all | 11:23 |
| apus | i'm trying to parse the output of "apt-get install --dry-run 'r-cran-*'" which shows lines at the beginning: "Note, selecting 'r-cran-gnm' for glob ...". Where is this written to and why can't i pipe it through grep? redirecting stdout and stderr to files doesn't show those lines either. | 11:32 |
| tomreyn | you need to read up on stdout and stderr | 11:34 |
| tomreyn | or, if you don't want to understand what you're doing, just add 2>&1 before the pipe | 11:35 |
| apus | tomreyn: ubuntu 18.04, apt-get install --dry-run 'r-cran-*' &> file; grep selecting file no output. | 11:35 |
| apus | i also tried 2>&1, nothing works. is something wrong with my tty? this is bash 4.4.18. | 11:36 |
| EriC^^ | apus: does 'cat file' show anything? | 11:37 |
| apus | yes, starts with Reading package lists... Building dependency tree... Reading state information... and then continues with r-cran-gregmisc is already the newest version ... but the stuff in between is missing | 11:38 |
| apus | is apt-get writing this directly to my terminal instead of to stdout? | 11:39 |
| tomreyn | i think it writes it to stderr | 11:39 |
| apus | would show up with &> , which is just short for 2>&1 > | 11:39 |
| tomreyn | hmm right it goes to stdout | 11:41 |
| EriC^^ | odd | 11:41 |
| tomreyn | apt-get install --dry-run ubiquity-casper 1> /tmp/file 2>/dev/null ; cat /tmp/file | nc termbin.com 9999 | 11:42 |
| tomreyn | -> https://termbin.com/l8l1 | 11:43 |
| tomreyn | this contains lines such as "Reading package lists..." | 11:43 |
| EriC^^ | tomreyn: i think you need to give it a wildcard to do the "note selecting" thing | 11:43 |
| tomreyn | right, those are lost | 11:44 |
| EriC^^ | apus: no idea on why, but a workaround you can do is "script -c "apt-get install -s 'r-cran-*'" file; grep selecting file | 11:45 |
| apus | or is there another way to get the list of packages that would be installed with r-cran-* ? | 11:45 |
| tomreyn | apt(-cache) depends | 11:45 |
| tomreyn | optionally with --recursive | 11:46 |
| EriC^^ | apus: apt list 'r-cran-*' shows them | 11:46 |
| tomreyn | things can get so easy when you start by asking the actual question | 11:46 |
| EriC^^ | tomreyn: he means the wildcard, not the deps of a particular package | 11:47 |
| apus | tomreyn: i need the dependency problems too, which i'm also parsing and the already installed packages. | 11:47 |
| tomreyn | i see | 11:47 |
| apus | i was just confused by these lines that kept disappearing | 11:47 |
| EriC^^ | apus: so you want to install all 'r-cran-*' packages, why bother with deps? apt should pull them in anyways | 11:48 |
| EriC^^ | or what's your actual objective here? | 11:48 |
| tomreyn | ^ | 11:48 |
| apus | there are dependency conflicts, i just want to install all additional packages, that don't cause problems with already installed R packages. | 11:49 |
| EriC^^ | why are you trying to script this? | 11:49 |
| EriC^^ | you hope to iterate them one by and see if they cause 'conflicts' ? | 11:51 |
| apus | because i want to put it in a Dockerfile and have no interest in manually removing the packages that cause problems. | 11:51 |
| apus | EriC^^: yes, i will remove those that appear with Breaks: or Depends: and see if it resolves within x iterations. as there is no option dedicated to what i want to do in apt-get, i don't see another option. | 11:52 |
| EriC^^ | maybe deal with why they are breaking? use a repo version program of that? | 11:53 |
| EriC^^ | say program A with ppa version is breaking these, replace it with repo version if you can? | 11:53 |
| apus | EriC^^: some are - from what i understand - not compatible with installed version of r-base-core, so the easiest choice is to exclude it for the time being. or am i understanding this wrong? | 11:54 |
| tomreyn | your goal should be to use only apt sources which are known to be compatible to one another | 11:56 |
| EriC^^ | apus: well i dont know what r-* is, but if you want you could just bruteforce it on a test vm or so, install the packages in a loop, then see which ones got installed from dpkg log and use those as your template, but yeah it seems a mess | 11:56 |
| tomreyn | cherry picking packages and package versions from different apt repositories which are not compatible (in that they packages installed from them introduce dependency conflicts) is a no, no. | 11:57 |
| EriC^^ | apus: i'd guess ideally if you wanted a newer version of program A, you'd either switch to a newer ubuntu version that has it, or maybe use another ppa for the r-base-core that doesnt conflict (and hopefully doesnt conflict your other repo programs, just a guess here) | 11:57 |
| apus | tomreyn: EriC^^: thank you both for your help. sadly i need multiple 3rd-party repos to get all packages, so i might not always be able to prevent conflicts. so it's not that easy. for the moment i'm staying at 18.04, as it is working otherwise. | 12:12 |
| CoDeAmRo | hey guys i need someone to help me with these two question | 12:22 |
| CoDeAmRo | 1. do i need to put antivirus on my ubuntu ? | 12:23 |
| BluesKaj | !virus | CoDeAmRo | 12:23 |
| ubottu | CoDeAmRo: Antivirus is something you don't need on !Linux, except where files are then passed to Windows computers (perhaps using Samba). See https://help.ubuntu.com/community/Antivirus | 12:23 |
| CoDeAmRo | 2. can anyone give me any good iptv servers to watch channels on my ubuntu | 12:25 |
| BluesKaj | CoDeAmRo, look for Fluxus and CCloud websites, they have m3u playlist stream urls you can run in vlc | 12:28 |
| CoDeAmRo | thanks for the replies and support | 12:32 |
| cluelessperson | I don't know what to do | 12:34 |
| cluelessperson | I'm at my wits end | 12:34 |
| cluelessperson | Firefox, Chrome, whatever | 12:34 |
| cluelessperson | if I so much as download a large file, my system slows to an unusable crawl | 12:34 |
| BluesKaj | cluelessperson, downloading what kind of file ? | 12:36 |
| cluelessperson | BluesKaj, in this case, it's a file from mega.nz, 1GB | 12:36 |
| cluelessperson | BluesKaj, sometimes, it's just a large react application in browser, like GCP | 12:36 |
| cluelessperson | which all should be able to function flawlessly | 12:36 |
| MrElendig | does it happen if you fire up iperf3/speedtest/similar too? | 12:37 |
| MrElendig | and what hardware is this? | 12:37 |
| cluelessperson | MrElendig, doesn't seem to be an issue with speedtest.net | 12:38 |
| cluelessperson | MrElendig, nor running perf3 in the background. | 12:38 |
| MrElendig | does it also happen with local file copy? | 12:38 |
| cluelessperson | MrElendig, Yes it does, when copying to sd cards and such | 12:38 |
| cluelessperson | not as bad, but yes. | 12:39 |
| BluesKaj | cluelessperson, is the ubuntu file indexer active? "Tracker" | 12:41 |

| ikarus987 | Hi guys i really messed up. I disabled root login :( by accident is there any fix i can do} | 12:53 |
| DarkTrick | Am I doing something wrong? | 12:53 |
| cluelessperson | ikarus987, disabled it how? | 12:53 |
| DarkTrick | can you disable root? | 12:54 |
| cluelessperson | DarkTrick, you can disable the ability to access root by various means. | 12:54 |
| ikarus987 | i did it by command | 12:55 |
| aiena | ikarus987, disabled how | 12:55 |
| aiena | as in disabled over SSH | 12:56 |
| aiena | what command did you use | 12:56 |
| ikarus987 | sudo passwd -l root | 12:57 |
| ikarus987 | this | 12:57 |
| ikarus987 | can i fix it.. other than reinstall ubuntu on that server? | 12:58 |
| cluelessperson | ikarus987, yes. passwd --unlock root | 12:59 |
| cluelessperson | ikarus987, do you have access to the system as another user? | 12:59 |
| ikarus987 | well i dont think so :\ | 13:00 |
| ikarus987 | since the sudo command | 13:00 |
| ikarus987 | sudo commands are not working now | 13:00 |
| ikarus987 | for other users | 13:00 |
| ikarus987 | but i do have access to the files and such in winSCP | 13:01 |
| ikarus987 | maybe i can edit text documents } | 13:01 |
| ikarus987 | ? | 13:01 |
| cluelessperson | ikarus987, is winSCP using an ssh key? | 13:02 |
| ikarus987 | i logged in as root | 13:02 |
| ikarus987 | in winSCP | 13:02 |
| ikarus987 | no ssh was setup | 13:02 |
| cluelessperson | what? | 13:03 |
| ikarus987 | just vanilla login with user and password | 13:03 |
| cluelessperson | okay | 13:03 |
| ikarus987 | yes i mean i am logged in using ssh | 13:03 |
| cluelessperson | I don't know what passwd -l does exactly | 13:03 |
| * cluelessperson test | 13:03 | |
| * cluelessperson tests | 13:03 | |
| ikarus987 | well according to some documents on a web it says it disabled root login | 13:03 |
| ikarus987 | u cant login as root anymore | 13:04 |
| ikarus987 | so since i haven't closed winscp since i did that command | 13:04 |
| ikarus987 | wondering if i could edit documents from there | 13:04 |
| ikarus987 | ? | 13:04 |
| cluelessperson | ikarus987, I just checked. passwd --lock user seems to remove the password for a use in /etc/shadow | 13:05 |
| ikarus987 | so the root user is still there? | 13:05 |
| ikarus987 | yes | 13:05 |
| cluelessperson | ikarus987, You can use winSCP root access to modify /etc/shadow and set a new password. | 13:06 |
| ikarus987 | how come i cant use sudo commands | 13:06 |
| cluelessperson | wait | 13:06 |
| ikarus987 | k | 13:06 |
| cluelessperson | ikarus987, check out /etc/groups and see if the sudo: group containers your user | 13:06 |
| cluelessperson | contains | 13:06 |
| ikarus987 | just so we're clear | 13:06 |
| ikarus987 | i could use the sudo command for my user before | 13:07 |
| ikarus987 | i did that passwd -l root | 13:07 |
| cluelessperson | ikarus987, I don't know how the heck you're still accessing files with winSCP | 13:07 |
| cluelessperson | unless you already logged in and haven't logged out yet | 13:08 |
| ikarus987 | yes | 13:08 |
| ikarus987 | i did not logout | 13:08 |
| ikarus987 | that's why | 13:08 |
| cluelessperson | well if you do logout, we can edit it another way | 13:08 |
| cluelessperson | but for now, stay logged in | 13:08 |
| cluelessperson | and modify the password of /etc/shadow for root | 13:08 |
| ikarus987 | hmm what do i edit in there | 13:09 |
| ikarus987 | my user is there | 13:09 |
| ikarus987 | ? | 13:09 |
| ikarus987 | :99999:7::: | 13:10 |
| ikarus987 | the ending... of my user line | 13:10 |
| ikarus987 | i think its what permission i have | 13:11 |
| ikarus987 | :7::: | 13:11 |
| ikarus987 | cluelessperson u there? | 13:13 |
| cluelessperson | ikarus987, `openssl passwd -6 -salt $(date +"%Y%M%d%H%M%S") "<new_password>"` | 13:13 |
| cluelessperson | ikarus987, that command will output a salted hash for a password | 13:14 |
| cluelessperson | ikarus987, you can replace the ! for the root line in /etc/shadow to set the new password for that hash | 13:14 |

| glachas | I am not able to ping another ubuntu device(this one is connected via hotspot of mobile). The 1st one is through wifi. | 14:28 |
| Turboginger | are they on seperate networks? are you trying to ping a local IP from a seperate network? | 14:29 |
| glachas | Yeah both are on different network | 14:29 |
| Turboginger | then you wouldn't be able to ping each machine directly, unless you have like port forwarding -- only your WAN addresses.. | 14:30 |
| glachas | What is required in order to ping other machine | 14:31 |
| leftyfb | glachas: them being on the same network | 14:31 |
| leftyfb | glachas: why do you need them to ping? | 14:31 |
| Turboginger | kind of depends on what you are trying to do, if you are trying to ping the one that is on your local network (non hotspot) you need to set up port forwarding | 14:31 |
| Turboginger | like are you trying to set up an FTP or webserver? | 14:32 |
| glachas | I order to access files of another machine. Or controlling through putty | 14:32 |
| glachas | in* leftyfb | 14:32 |
| Turboginger | yeah, I would recommend watching a quick video on port forwarding for ssh | 14:32 |
| leftyfb | glachas: setup port forwarding for the one on the non-mobile connection to forward ssh listening on a different port other than 22 | 14:32 |
| Turboginger | it has to do with router configuration more than the machines itself | 14:32 |
| Turboginger | pretty simple stuff. probably <30 mins from n00b to knowing how | 14:33 |
| glachas | If both the machines are connected to different networks we cant ping each other? | 14:33 |
| glachas | is it? | 14:33 |
| leftyfb | glachas: forget about ping | 14:34 |
| leftyfb | glachas: https://www.omgubuntu.co.uk/2017/06/wormhole-fast-secure-way-send-files-users-cli maybe use something like that | 14:34 |
| leftyfb | glachas: or dropbox or box.com or google drive | 14:34 |
| glachas | I will try. But I have one question, how we are able to ping other websites? | 14:36 |
| Turboginger | That's a big question, but basically domain name servers (DNS) assign an IP or IPs to a domain name (like google.com) | 14:37 |
| Turboginger | so like on your machine that is not on the hotspot go to ipchicken.com | 14:37 |
| Turboginger | that is your public facing IP | 14:38 |
| Turboginger | to an external user, all of your computers have that IP | 14:38 |
| Turboginger | depending on the service you want to use, you need to set up port forwarding to a specific internal ip | 14:38 |
| glachas | leftyfb: I am using FileZIla in order to connect to the other machine (that is running via hotspot). So I think here also the same reason that I am not to connect. | 14:40 |
| glachas | Turboginger: So I need to setup port forwarding in machine that is running via hotspot | 14:40 |
| glachas | Then I will be able to connect through other machine | 14:41 |
| glachas | is it? | 14:41 |
| Turboginger | @glachas it depends on which machine is hosing the ftp | 14:42 |
| Turboginger | and you set up port forwarding on yoru router, not either machine. | 14:42 |
| glachas | But I dont have control over routers. So how will I be able to do it | 14:43 |
| tomreyn | if both endpoints of the connection are behind NAT, then FTP is the worst choice of protocol you could make. | 14:49 |
| tomreyn | especially so if you can't do port forwarding on either end | 14:50 |
| tomreyn | glachas: what are you trying to achieve there? transfer a file from one computer behind NAT to another computer behind NAT in a different network? | 14:51 |
| glachas | For port forwarding we need to have admin access to routers. Is it? | 14:52 |
| tomreyn | glachas: i'll answer your question as soon as you answered mine. | 14:53 |
| glachas | tomreyn: I need to access machine(ubuntu installed) remotely. and control it via putty and will be able to transfer files to-n-fro | 14:55 |
| tomreyn | glachas: this is an easy way to do so: https://pagekite.net/ - it's a commercial service with a free tier, i think. but, from what i rmeember, all of the software is open source. so don't consider this a recommendation or endorsement, but i think it can work well for your use case. | 14:57 |
| cren | sorry, this is not quite an ubuntu question, but: does anyone know how to make `ufw` allow traffic from a specific IP address for a specific app? I'm trying things like `ufw allow from $ADDRESS to any ssh` but I'm getting syntax errors from ufw | 14:58 |
| tomreyn | glachas: and the answer to your earlier question: yes, to configure and manage port forwarding on a router you will usually need administrative access or an access level that grants you access to this functionality. (how exactly it is done could depend on the specific router.) | 15:00 |
| tomreyn | glachas: for network questions, you may be better served in ##networking | 15:00 |
| glachas | tomreyn: Thank you for your valuable suggestions. | 15:01 |
| tomreyn | cren: i don't think ufw has the capability to do application level traffic filtering. it only does so by port numbers / service ports, as far as i know. | 15:01 |
| tomreyn | glachas: you're welcome | 15:02 |
| cren | tomreyn: you can do e.g. `ufw allow ssh` | 15:02 |
| tomreyn | cren: yes, and then iptables looks up "ssh" in /etc/services and finds that it is port 22 | 15:03 |
| tomreyn | 22/tcp rather | 15:03 |
| tomreyn | so "ssh" is just a placeholder for that really, "TCP port 22" | 15:03 |
| cren | tomreyn: okay I'll just use the ports then. I just thought that one would be able to use ssh like I was trying to and I was making a silly syntax error | 15:04 |
| === quadrathoch24 is now known as quadrathoch2 | ||

| CameronBraid | help. .. | 15:06 |
| cren | I managed to use `ufw allow from $ADDRESS to any port 22` | 15:06 |
| tomreyn | cren: sorry, i explained this incorrectly. ufw actually has "profiles" where it internally defines that "ssh" is 'the service at port 22'. it doesn't pass "ssh" to iptables. | 15:07 |
| tatertots | any port 22? | 15:07 |

| tomreyn | CameronBraid: yes that seems to be what you said - sorry. ;-) so i'd say file a bug against the kernel where it didn't work then. and look for existing bug reports on this problem. | 15:10 |
| pymagic | how do i run my own program when the user logs into gnome | 15:12 |
| pymagic | on ubuntu 20.04lts | 15:13 |
| CameronBraid | tomreyn: yep the -ga kernel has an issue that the -hwe-edge fixes.. i'm very relieved ! | 15:13 |
| tomreyn | CameronBraid: i'm glad you found a workaround then. | 15:14 |
| tomreyn | pymagic: this is not a software development support channel (try #python), but you probably want to create a .Desktop file in ~/.local/share/applications/ | 15:17 |
| tomreyn | https://specifications.freedesktop.org/desktop-entry-spec/latest/ | 15:18 |
| pymagic | tomreyn, thanks. | 15:18 |
| cluelessperson | man, I think I've screwed myself | 15:21 |
| cluelessperson | I think my issues may just be my 8GB of ram simply isn't enough in this day and age. | 15:21 |
| cluelessperson | but I can't upgrade to 16GB | 15:21 |
| cluelessperson | soldered on ram. :/ | 15:21 |
| cluelessperson | I wonder if I can configure ubuntu to use swap more aggressively | 15:22 |
| tomreyn | <tomreyn> cluelessperson: the linux-*-lowlatency* kernel images may help there, as well as tweaking the /sys/vm kernel parameters | 15:27 |
| cluelessperson | tomreyn, what do those do? :P | 15:28 |
| tomreyn | cluelessperson: change how linux handles virtual memory (which swap is a form of), amongst other | 15:28 |
| tomreyn | and there's documentation and many articles about it, of course. | 15:29 |
| cluelessperson | tomreyn, I've just modified my "swappiness" | 15:29 |
| tomreyn | swappiness is the easiest setting to start with | 15:29 |
| cluelessperson | sitting at ~500Mi | 15:30 |
| tomreyn | is this still about downloading from a specific website? | 15:30 |
| tomreyn | where downloads must be stored in ram, then decrypted, then stored to disk? | 15:30 |
| cluelessperson | tomreyn, eh, downloading from that certain website appears to aggravate it a lot, but no, it's not just one website | 15:31 |
| cluelessperson | I seem to be constantly fighting ram issues | 15:31 |
| cluelessperson | tomreyn, I'm about to try the low latency kernel, just looking up how to switch to it. :) | 15:31 |
| tomreyn | cluelessperson: which ubuntu version are you on, which kernel version? | 15:32 |
| tomreyn | nc termbin.com 9999 < <(lsb_release -ds;cat /proc/{version,cmdline};echo "Session: $XDG_CURRENT_DESKTOP ($XDG_SESSION_TYPE)";echo Shell: $SHELL) | 15:32 |
| cluelessperson | tomreyn, https://termbin.com/s1p0 | 15:33 |
| tomreyn | intel pstate issues? | 15:33 |
| cluelessperson | tomreyn, I was messing with it, I should probably re-enable | 15:34 |
| tomreyn | to install the lowlatency kernel, you run: sudo apt update && sudo apt install linux-image-lowlatecy | 15:34 |
| tomreyn | that's wrong, let me correct it | 15:34 |
| tomreyn | to install the lowlatency kernel, you run: sudo apt update && sudo apt install linux-lowlatency | 15:35 |
| * cluelessperson apt searches lowlatency | 15:35 | |
| cluelessperson | tomreyn, so my understanding of this so far is that it's a kernel configured towards less overall bandwidth, and less/better latency? | 15:36 |
| cluelessperson | so faster context switching, maybe? | 15:36 |
| tomreyn | cluelessperson: since you'Re on eoan (19.10), which will hit EOL in 20 days, maqybe you should just upgrade instead? | 15:37 |
| cluelessperson | wut | 15:38 |
| cluelessperson | ah | 15:38 |
| cluelessperson | tomreyn, ah, I should probably shift to 20.04 then. :P | 15:39 |
| cluelessperson | brb, rebooting | 15:39 |
| tomreyn | cluelessperson: lowlatency is merely about faster context switching, yes. it could improve your chances of regaining vcontrol over the system when it starts becoming unresponsive. | 15:40 |
| tomreyn | *control | 15:40 |
| === halvors1 is now known as halvors | ||
| cluelessperson | tomreyn, alright, uname -a shows that the lowlatency kernel is being used. :D | 15:48 |
| kyle__ | is sysrq enabled by default on ubuntu desktops (18.04 in particular)? | 15:48 |
| tonyt | ubuntu now includes adds? didnt see that one comming | 15:57 |
| cluelessperson | tonyt, I don't think so? | 15:58 |
| tonyt | https://news.softpedia.com/news/canonical-under-fire-for-putting-ads-in-the-ubuntu-motd-530372.shtml | 15:58 |
| tonyt | article from yesterday | 15:58 |
| tonyt | abouts adds in ubuntu now | 15:58 |
| cluelessperson | tonyt, I'm extremely angry when it comes to advertising | 15:58 |
| tonyt | me too cluelessperson. | 15:58 |
| cluelessperson | tonyt, if ubuntu starts implementing ads, I'm leaving | 15:58 |
| tonyt | no doubt. same | 15:58 |
| corrupt | i'm using a laptop with two external monitors. the external monitors are detected, but for whatever reason I can only extend the display to one of the external monitors. how do I fix this? | 16:02 |
| cluelessperson | tomreyn, I'm about to dist-upgrade. :P so far things seem far more responsive. | 16:02 |
| cluelessperson | brb | 16:02 |
| * cluelessperson fires! | 16:03 | |
| === newdimension_ is now known as newdimension | ||

| chick1 | Hey everyone! | 16:19 |
| chick1 | I have some troubles installing a game on Ubuntu and was wondering if anyone is here having experience with the "battle.net" installer on Ubuntu 20.04 for playing world of warcraft | 16:19 |
| chick1 | Im already in the gaming for linux IRC too but there is noone there atm who can help me really | 16:20 |
| SonicPotato | what would I do to find the process causing high disk i/o? | 16:25 |
| SonicPotato | iotop seems to be the answer but i get an error running it in a container | 16:28 |
| yuta | SonicPotato:sudo iotop | 16:36 |
| yuta | or error messages? | 16:36 |
| SonicPotato | i found the answer here https://github.com/lxc/lxd/issues/3797 | 16:37 |
| yuta | ok | 16:37 |
| SonicPotato | had to run iotop on host with some flags | 16:38 |
| yuta | ok | 16:38 |
| SonicPotato | turns out mono was running with --debug so it was logging everything, ~30mb/sec | 16:40 |
| cluelessperson | tomreyn, I just performed a dist-upgrade | 16:41 |
| cluelessperson | Right off low-latency seems to really be helping | 16:42 |
| cluelessperson | tomreyn, you've really helped make my month better. :) | 16:51 |
| cluelessperson | probably my life for next couple months, actually | 16:51 |
| birdman007 | what is a good gba emulator? | 16:57 |
| scatterp | hi how can I diff 2 folders and copy the differences line by line with confirmation without modifying ownership or chmod settings? | 17:03 |
| leftyfb | scatterp: mirror the files/subdirectories in each? | 17:04 |
| scatterp | yeah | 17:05 |
| leftyfb | scatterp: rsync, though it doesn't have confirmation. You can run it in dry run mode and look over what it's going to do first | 17:06 |
| leftyfb | scatterp: or write your own script | 17:07 |
| scatterp | hrm ok | 17:07 |
| scatterp | yeah writing a script i guess is the way | 17:07 |
| scatterp | ok thanks | 17:07 |
| pymagic | does anyone know where logs are stored for applications in ~/.local/share/application? | 17:11 |
| pymagic | Mine dont seem to be executed | 17:11 |
| EriC^^ | which one pymagic | 17:12 |
| pymagic | EriC^^, Let me test again. It seems it was missing executable permission. Perhaps that was it | 17:12 |
| pyraindrop | EriC^^, I wrote a small application - the desktop file launches my program. It's not running it | 17:14 |
| EriC^^ | pyraindrop: what's in the desktop file? | 17:15 |
| EriC^^ | the Exec= part | 17:15 |
| pyraindrop | EriC^^, Exec=~/wallpapers/code.py --change | 17:15 |
| pyraindrop | EriC^^, is there a log for these errors? | 17:17 |
| EriC^^ | pyraindrop: try to give it the complete path, not ~ (it's not bash) also you expect it to run in the background right, no terminal popping up | 17:17 |
| pyraindrop | yes | 17:17 |
| pyraindrop | trying | 17:17 |
| Ketzer | so i just purged uninstalled packages that left config files behind, and one of them was an old kernel... it gave the message "dpkg: warning: while removing linux-modules-5.4.0-26-generic, directory '/lib/modules/5.4.0-26-generic' not empty so not removed" | 17:26 |
| Ketzer | can i remove that directory manually? | 17:27 |
| pyraindrop | EriC^^, doesnt seem to work, no matter what i do | 17:28 |
| pyraindrop | complete paths dont work | 17:28 |
| pyraindrop | if i run the same Exec command in bash - works - no output on stdout | 17:28 |
| pyraindrop | I tried to add the executable in StartupApplications for gnome - that does not work either | 17:29 |
| EriC^^ | pyraindrop: try this 'Exec=gnome-terminal -e "/path/to/bla.py"' see what happens | 17:29 |
| EriC^^ | pyraindrop: try first to just double click the desktop file (with it +x) and see what happens | 17:29 |
| pyraindrop | EriC^^, if i double click the file, it opens it up in an editor! | 17:31 |
| pyraindrop | if i right click on it, there is no "Run" option | 17:31 |
| EriC^^ | pyraindrop: is the file +x ? | 17:31 |
| pyraindrop | yes | 17:31 |
| EriC^^ | try to right click properties | 17:32 |
| EriC^^ | 1 sec | 17:32 |
| pyraindrop | gnome-terminal -e "/path/to/bla.py" -- this works flawlessly | 17:32 |
| pyraindrop | Execute is true in properties | 17:32 |
| pyraindrop | In Properties "Open with " is set to text editor | 17:32 |
| ioria | pyraindrop, might be a ' sleep ' problem :þ give it one, 4 , maybe 5 secs | 17:33 |
| pyraindrop | ioria, I've given it all the time since I logged back in | 17:33 |
| pyraindrop | been minutes | 17:33 |
| EriC^^ | pyraindrop: is there a "run" program you can assign it to? | 17:34 |
| pyraindrop | it takes <0.1 seconds if i run it | 17:34 |
| ioria | pyraindrop, nope, you don't get me | 17:34 |
| pyraindrop | ioria, you are suggesting, I add a sleep to it? | 17:34 |
| ioria | pyraindrop, yes | 17:34 |
| pyraindrop | goodpoint | 17:34 |
| EriC^^ | that really depends on what it does | 17:34 |
| pyraindrop | let me try | 17:34 |
| ioria | pyraindrop, in the Exec line | 17:34 |
| EriC^^ | pyraindrop: try to simplify it, make the .py a bash script that just does "echo something > /tmp/myscript" | 17:35 |
| Phruis | does anyone have a NAS built based on Ubuntu? | 17:37 |
| IaMnEwHeRe | Phruis, does glusterfs count? | 17:37 |
| Phruis | i dont know never heard of it | 17:37 |
| Phruis | IaMnEwHeRe is it easy to use? | 17:38 |
| IaMnEwHeRe | yes. | 17:38 |
| ikarus987 | wondering /etc/init.d/sshd restart hmm boy and girls why that file does exist in my directory? | 17:38 |
| ikarus987 | doesn't########## | 17:39 |
| ikarus987 | how do i restart this :\ | 17:39 |
| IaMnEwHeRe | ikarus897, systemd | 17:39 |
| Phruis | i really want something easy to manage | 17:39 |
| IaMnEwHeRe | what is your use-cae? | 17:39 |
| Phruis | im trying to figure out how to have a setup where I can have my plex setup and then something like NextCloud | 17:40 |
| Phruis | wanted to have a central location for file storage for that | 17:40 |
| IaMnEwHeRe | plex setup? | 17:40 |
| Phruis | i have an intel xeon system sitting | 17:40 |
| Phruis | basically media center | 17:41 |
| IaMnEwHeRe | you do not need gluster then | 17:41 |
| Phruis | it would make a good NAS i think | 17:41 |
| IaMnEwHeRe | nextcloud runs without cluster, have been using it without gluster so far on my server all fine | 17:41 |
| Phruis | thats cool | 17:41 |
| Phruis | i was looking at synology because it seems so easy | 17:42 |
| Phruis | but i do have a xeon system just sitting basically doing nothing | 17:42 |
| Phruis | so maybe i should try and use that? | 17:42 |
| IaMnEwHeRe | gluster that is not cluster, if you want to attach a media-center then you would need something like webdave or sambe, I think gluster can do samba of nfs in general | 17:42 |
| IaMnEwHeRe | Phruis, do you want it to be reachable from outside your lan? | 17:43 |
| pyraindrop | EriC^^, no luck. | 17:43 |
| ioria | pyraindrop, mate, this location is wrong '~/.local/share/application' ; you need the .desktop file in .config/autostart/ | 17:43 |
| Phruis | Phruis not a requirement at the moment, but it might be handy | 17:43 |
| pyraindrop | ioria, its not a sleep problem | 17:43 |
| Phruis | I have a pfsense box that has dynamic dns setup | 17:43 |
| Phruis | so i think that would be easy | 17:43 |
| Phruis | but i could be wrong | 17:43 |
| Phruis | would require a lot of port forwards probably | 17:43 |
| pyraindrop | ioria, on ubuntu 20.04LTS - is the location .config/autostart? | 17:43 |
| ioria | pyraindrop, as always, amte | 17:44 |
| ioria | pyraindrop, just run gnome-session-properties | 17:44 |
| pyraindrop | k trying | 17:44 |
| pyraindrop | ioria, I tried that - that does not work | 17:44 |
| ioria | pyraindrop, that does not work not helping | 17:44 |
| pyraindrop | ioria, I added /usr/bin/bash -c "/home/uname/project/wallpaper.py --change" in gnome-session-properties | 17:45 |
| pyraindrop | ioria, no effect | 17:45 |
| IaMnEwHeRe | Phruis, there is also freenas, which is a distro specializing in that kind of stuff, but I do not have experience with that, but it looks like more what you would want | 17:45 |
| Phruis | cool thanks will check it out | 17:45 |
| pyraindrop | ioria, gnome-session-properties is creating .desktop files in ~/.config/autostart | 17:47 |
| ioria | pyraindrop, yes, i know | 17:47 |
| pyraindrop | but it looks like its being ignored for my .desktop file | 17:47 |
| pyraindrop | what is suprising it - these files dont have executable permissions! | 17:48 |
| ioria | that's not the problem, i guess | 17:48 |
| pyraindrop | does it make a difference if i do bash -c "xxx" or gnome-terminal -e "xxx" or "xxx"? | 17:49 |
| ioria | pyraindrop, so, make an executable bash script with : shebang; sleep 5 and /home/uname/project/wallpaper.py ; then open gnome-session-properties and make a new auto launcher with the script full path | 17:50 |
| pyraindrop | k - logging off and trying | 17:52 |
| pyraindrop | ioria, .config/autostart is not running my .desktop command for sure | 18:06 |
| pyraindrop | no idea why | 18:06 |
| pyraindrop | EriC^^, ioria, https://paste.ubuntu.com/p/hbDTtnWbBM/ | 18:08 |
| ioria | pyraindrop, i'am pretty sure that's not how gnome-session-properties set the .desktop file | 18:10 |
| ioria | pyraindrop, that's your hand made file | 18:10 |
| ioria | pyraindrop, and that's not how i told you to test | 18:11 |
| EriC^^ | pyraindrop: do this please, Exec="bash -c 'touch /tmp/blabla'" | 18:19 |
| EriC^^ | add it to the startup apps, then logout and back in | 18:19 |
| EriC^^ | see if /tmp/blabla now exists | 18:19 |
| pyraindrop | ioria, that file I pasted was generated by gnome-session-properties | 18:20 |
| pyraindrop | EriC^^, trying that now | 18:20 |
| ioria | pyraindrop, nope, if that would be true, the Exec line would point the bash script and not the .py script | 18:21 |
| pymagic | EriC^^, Exec="bash -c 'touch /tmp/blabla'" --> No blabla :( | 18:22 |
| ioria | pyraindrop, nope, if that would be true, the Exec line would point the bash script and not the .py script | 18:22 |
| IaMnEwHeRe | pyraindrop, does it have to be a .desktop-file? couldn't it also be $HOME/.profile $HOME/.bashrc or a systemd-configuration like here https://unix.stackexchange.com/questions/590635/systemd-service-that-runs-only-for-one-user-and-as-root | 18:23 |
| EriC^^ | pymagic: ah same here, let me see whats wrong 1 sec | 18:24 |
| EriC^^ | pymagic: try without the quotes after Exec | 18:24 |
| EriC^^ | only Exec=bash -c 'touch /tmp/blabla' | 18:24 |
| EriC^^ | that did it for me | 18:24 |
| EriC^^ | pymagic: actually just Exec=touch /tmp/blabla should do it | 18:26 |
| EriC^^ | pymagic: if that works, try Exec=bash -c '/path/to/script.py > /tmp/blabla 2>&1' | 18:29 |
| ScottHDev | Hello, I'm packaging a library and a binary. I've added a line in debian/install to explicitly install the binary. In the output of debuild I see Installing <executable> to <dest dir>. But when I reinstall the package I don't see this executable in /us/bin?r | 18:29 |
| ScottHDev | Wha could I do? | 18:29 |
| ScottHDev | I that debian only allows to install library stuff in a library package | 18:30 |
| pymagic | EriC^^, trying without quotes - did that work at your end? | 18:36 |
| pymagic | Exec=touch /tmp/blabla | 18:36 |
| pymagic | does that work? | 18:36 |
| ScottHDev | Found | 18:37 |
| ScottHDev | I just had to use debian/<packagename>.install | 18:37 |
| MMZF | hello, will ubuntu work well with dde? | 18:40 |
| alschaapman | MMZF: It's not even in the official repos, is it? | 18:41 |
| MMZF | just a suggestion needed | 18:42 |
| MMZF | if someone have tried or have any idea | 18:42 |
| alschaapman | I don't think you should use it. openSUSE stopped carrying their packages because of inaction on security-related bug reports by the developers. Currently it looks like just Arch and Fedora are packaging it, if pkgs.org is to be believed | 18:43 |
| MMZF | the deepin desktop environment? | 18:43 |
| alschaapman | Yes | 18:43 |
| MMZF | hmm | 18:44 |
| BeavisOnFire | There's UbuntuDDE Remix | 18:44 |
| MMZF | any other suggestion for a better look? | 18:44 |
| MMZF | BeavisOnFire: ikr it works great without updating i mean on a fresh install | 18:44 |
| alschaapman | If you're shopping for a desktop environment (and presumably you don't like GNOME, which is understandable), Xfce and KDE Plasma are both excellent. | 18:45 |
| alschaapman | In terms of overall polish and features Plasma is probably the best alternative to DDE | 18:45 |
| MMZF | but after updating softwares it's eww | 18:45 |
| MMZF | so alschaapman plasma will work great on my ubuntu 20.4? | 18:46 |
| BeavisOnFire | Installing several DEs is tricky | 18:46 |
| alschaapman | BeavisOnFire: Meh. I used to have that experience way back in the day but as of the last several years I don't think that's a big issue any more | 18:47 |
| MMZF | im going to try plasma on a fresh install of ubuntu 20 | 18:47 |
| BeavisOnFire | Good luck uninstalling the ones you don't like without messing your install | 18:47 |
| BeavisOnFire | Just use a VM or a liveCD | 18:48 |
| alschaapman | MMZF: Just install the kubuntu-desktop package | 18:48 |
| BeavisOnFire | and play with DEs | 18:48 |
| IaMnEwHeRe | MMZF nothing beats a shell from the looks of it | 18:48 |
| * IaMnEwHeRe smiles | 18:48 | |
| IaMnEwHeRe | Try awsome or i3 | 18:48 |
| MMZF | hmm | 18:48 |
| IaMnEwHeRe | steep learningcurve but I never missed it | 18:49 |
| alschaapman | I think you may get asked by a package script if you want to switch your display manager to SDDM. If you're just trying out, I would recommend that you not do that just yet | 18:49 |
| pymagic | EriC^^, Exec=touch /tmp/blabla - this works! | 18:49 |
| alschaapman | SDDM is the display manager that KDE recommends, but it lacks some pretty important features that GDM has, such as rootless X. It's one of the best DM options for theming and customization options, though. | 18:49 |
| MMZF | deepin looks good like mac osx | 18:49 |
| MMZF | but it got issues | 18:50 |
| MMZF | so plasma will be ok? | 18:50 |
| BeavisOnFire | lol | 18:50 |
| BeavisOnFire | Try DEs | 18:50 |
| BeavisOnFire | Asking online won't help you much | 18:50 |
| alschaapman | Plasma is fantastic. Pretty much all the KDE apps are great | 18:50 |
| BeavisOnFire | To each his own | 18:50 |
| alschaapman | That's no guarantee that it will be your favorite, or even that you will like it, though. | 18:50 |
| MMZF | BeavisOnFire: bruh i'm just saying my time | 18:51 |
| MMZF | saving* | 18:51 |
| BeavisOnFire | You can't save your time by asking people online "will I like fries with mayonnaise ?" | 18:51 |
| alschaapman | I think Plasma is generally the best recommendation for people who are used to commercial OSes like Windows or macOS, though. | 18:51 |
| BeavisOnFire | Download the iso | 18:51 |
| BeavisOnFire | Use a VM | 18:51 |
| BeavisOnFire | or a live CD | 18:51 |
| BeavisOnFire | Test the DE yourself | 18:52 |
| MMZF | my system do not have a hardware acceleration :/ | 18:52 |
| BeavisOnFire | Personally, I tried Plasma a year ago, didn't like it at the time. It was buggy/crashy and GTK apps looked like crap. | 18:53 |
| BeavisOnFire | But it looked really nice on Unixp | 18:53 |
| MMZF | BeavisOnFire: live CD option hmm | 18:53 |
| BeavisOnFire | Unixp*rn pictures | 18:53 |
| BeavisOnFire | I like MATE, it's highly tweakable | 18:53 |
| alschaapman | Well, you're going to be hard pressed to run a desktop environment with fancy graphical effects like you can get used to on macOS if you have serious hardware limitations | 18:53 |
| BeavisOnFire | Still, it lacks features | 18:53 |
| alschaapman | But Xfce should run well on less powerful hardware | 18:54 |
| alschaapman | xubuntu-desktop would be the package if you want to try that | 18:54 |
| MMZF | i said UbuntuDDE was also great on fresh install but after updating software packages it become messy | 18:54 |
| MMZF | so live CD option fail | 18:54 |
| alschaapman | I think there is enough consensus on the matter of issues with Deepin that you should stay away from it for now. | 18:55 |
| MMZF | yup | 18:55 |
| MMZF | found so many errors within a day :/ omg | 18:55 |
| alschaapman | In the past I have tended to find concerns about Chinese influence on Deepin to be FUD -- it is fully open source, after all -- but again, there's the matter of security bug reports not getting any attention from the developers | 18:56 |
| alschaapman | I don't know if that's the only reason more distributions don't package it, but again, openSUSE stopped including it in their repos for exactly that reason, and I would take my cues from the openSUSE guys there, because they're pretty good | 18:57 |
| EriC^^ | pymagic: ok, great | 18:57 |
| EriC^^ | pymagic: try Exec=bash -c '/path/to/script.py > /tmp/blabla 2>&1' | 18:58 |
| EriC^^ | check /tmp/blabla as it's the log | 18:58 |
| IaMnEwHeRe | I think he wants to run s.th. as a service in the background | 18:58 |
| MMZF | alschaapman: any idea will ubuntu work well on old systems? i mean dual core almost 10 years old | 18:58 |
| MMZF | nvm im not messing with de | 18:58 |
| MMZF | default is ok | 18:58 |
| coconut | MMZF, two distro's which come to mind when you want the look and feel of macos: 1) xfce 2) elementaryos | 18:59 |
| coconut | or you just theme around in the desktop env options | 19:00 |
| alschaapman | MMZF: Ubuntu's default desktop is probably going to be a little demanding on something that old, but it should still run mostly without bugs. If it's not fast enough for you, try Xfce. | 19:00 |
| MMZF | im just on a spin to test all os | 19:03 |
| MMZF | and find out which works well on this old machine | 19:03 |
| MMZF | and there was also many challenging things | 19:04 |
| MMZF | ubuntu based os like linux mint | 19:04 |
| IaMnEwHeRe | MMZF, no need to go all out, Linux is a kernel, so pretty much all setups work on one installation, configuration and aquisition of packages is the only problem | 19:04 |
| MMZF | i need speed only :/ | 19:04 |
| IaMnEwHeRe | Plus, when it comes to an OS look and feel should not be paramout | 19:04 |
| IaMnEwHeRe | MMZF go for a shell then | 19:05 |
| alschaapman | Well definitely don't go with Mint. | 19:05 |
| IaMnEwHeRe | nothing beats a CLI, UI is always a higher abstraction | 19:05 |
| alschaapman | If it's the Cinnamon desktop you want, it's in Ubuntu's official repos. | 19:05 |
| IaMnEwHeRe | consider how often you have to move from keyboard to mouse and you will end up with a tiling WM controlable via keyboard :) | 19:05 |
| MMZF | shell i already tried | 19:06 |
| MMZF | it's also slow | 19:06 |
| IaMnEwHeRe | alschaapman yes, but seeing that ubuntu wants to role out snaps or flatpacks only I wonder how long they stick to ubuntu before going to debian(?) | 19:06 |
| alschaapman | Flatpaks in Ubuntu? I don't think so. | 19:07 |
| alschaapman | Canonical is all in on snapd | 19:07 |
| alschaapman | Which is a shame, frankly | 19:07 |
| alschaapman | flatpak is probably in the Ubuntu repos -- I haven't checked -- but it would be a major reversal for them to start pushing that as a strategy when they've already invested so much in snapd, which does basically the same thing | 19:09 |
| IaMnEwHeRe | well, made me already ditch ubuntu for debian on my new server | 19:09 |
| alschaapman | I'm not sure why snapd is even a matter of concern for you in a server setting, but okay | 19:10 |
| IaMnEwHeRe | actually snaps are for desktop only | 19:10 |
| IaMnEwHeRe | atm | 19:10 |
| alschaapman | I mean I don't know about *only* | 19:10 |
| IaMnEwHeRe | It is more about controle, snaps are updated automatically and they are bigger in installation | 19:10 |
| alschaapman | I've very much gotten the impression that desktop is the focus for snapd though | 19:10 |
| alschaapman | Again my puzzlement about how this factors into your server admin decision making | 19:11 |
| IaMnEwHeRe | well you can if you want to, they are pushing for a default for desktop though | 19:11 |
| IaMnEwHeRe | always wanted to use debian, had a new server sitting around and they gave me an excuse | 19:11 |
| IaMnEwHeRe | :) | 19:11 |
| alschaapman | I definitely respect Debian but their packages are ANCIENT. | 19:12 |
| IaMnEwHeRe | not just that, but also the fact that their loginpage is actually telling them how often you log into your server | 19:12 |
| ProgrammAbel | join #lfs | 19:12 |
| IaMnEwHeRe | NEVER | 19:12 |
| IaMnEwHeRe | :) | 19:12 |
| ProgrammAbel | lol that was an accident | 19:13 |
| ProgrammAbel | :) | 19:13 |
| alschaapman | I'm in the process of deploying a new server as well and I chose Ubuntu because of Live Patch | 19:13 |
| IaMnEwHeRe | alschaampman, yes but what do you need? resourceabstraction, and for the rest, spin up docker | 19:13 |
| IaMnEwHeRe | with snaps thing though, it will be harder to use their packages, in s.th. like aur | 19:14 |
| IaMnEwHeRe | and the snapd-move and the loggin of when you log into your server makes me nervous | 19:14 |
| IaMnEwHeRe | ahh I found an article dealing with that, read it on some message board though https://ma.ttias.be/what-exactly-being-sent-ubuntu-motd/ | 19:18 |
| IaMnEwHeRe | and IMHO that is a no go, and with snapd .... not so attractive anymore, although I like the community, that is why I am hanging around | 19:18 |
| Sliss | after upgrading to 20.04 my virtualenv do not work any more, did anyone else had problems with theirs? Example error: No module named pip, while there is a pip in the bin folder | 19:41 |
| ioria | Sliss, try with pip3 | 19:42 |
| pymagic | ioria, EriC^^ It worked at last | 19:44 |
| worrelsik | Last week jeremy31 provided me with this Makefile in order to create a patched version of btusb.ko. Unfortunately I'm still out of luck. I'm now on 5.4.0-39-generic, and noticed that using make with an unpatched version btusb.c in ~/build/linux-5.4.0/drivers/bluetooth results in a btusb.ko that is 85048 bytes, whereas the original /lib/modules/5.4.0-39-generic/kernel/drivers/bluetooth/btusb.ko is 85865 bytes. | 19:44 |
| pymagic | Thanks for the help. | 19:44 |
| Sliss | Tried that but does not change anything the while environment doesn't work. Well I can activate it, but that's about it | 19:44 |
| Sliss | /while/whole/ | 19:45 |
| worrelsik | jeremy31, Isn't that strange? I'd expect them to be the same size | 19:45 |
| b1ack0p | hi | 19:45 |
| b1ack0p | how can i install xfce on ubuntu 20.04? | 19:45 |
| b1ack0p | and goodies too | 19:45 |
| worrelsik | That Makefile was https://github.com/jeremyb31/newbtfix-4.15/blob/master/Makefile | 19:46 |
| Sliss | b1ack0p: search for tha package via apt? | 19:46 |
| jeremy31 | worrelsik: I have never compared the sizes from kernel to patched versions | 19:46 |
| worrelsik | jeremy31, No, I meant the non-patched version | 19:47 |
| Sliss | b1ack0p: of install xubuntu I think it is called? | 19:47 |
| b1ack0p | isnt it same installing xfce on ubuntu = xubuntu? | 19:47 |
| b1ack0p | what could be different anyway | 19:48 |
| pymagic | Does anyone know how to write an application so that I can get a menu in the titlebar? | 19:48 |
| jeremy31 | worrelsik: oh, the btusb.c versus btusb.ko will definitely be different size | 19:50 |
| worrelsik | jeremy31: Also, when I run the make command with the patched btusb.c (the patch adds a few conditions) I'm again getting a btusb.ko with the size 85048 bytes. That should not be the same? | 19:51 |
| jeremy31 | worrelsik: That would depend on how many changes in the patch | 19:52 |
| pymagic | how do i get a menu of my application on the titlebar once the user logs in? I'm using .config/autostart/app.desktop to start my application at login | 20:02 |
| B0g4r7 | When did PIDs > 65535 become a thing? | 20:07 |
| filifunky | so after I upgraded to 20.04 I no longer have access to my backup harddrive. I taught myself chmod and chown and changed the permissions. I am able to get in on an xterm but nothing inside. When I try to see what's inside looking through "files" it still says I don't have access. "This location could not be displayed. You do not have the permissions necessary to view the contents" | 20:12 |
| filifunky | I'm hopeful that everything on that backup device didn't just disintegrate. anyone able to help to see if I can still access what's in there? | 20:13 |
| tomreyn | B0g4r7: didn'T you ask the same question her elike a week ago? and didn't we discuss it? | 20:13 |
| tomreyn | B0g4r7: i'll repeat the answer i think i provided last time we talked: i believe that the default setting of /proc/sys/kernel/pid_max changed sometime between 18.04 LTS and 20.04 LTS. i suggest checking the release notes of and between those releases, or to just test them if you need to know exactly. why are you asking anyways? | 20:19 |
| tomreyn | filifunky: can you work on a temrinal, yet? | 20:20 |
| tomreyn | * terminal | 20:20 |
| B0g4r7 | I didn't ask that before, no. Thanks. I'm not asking for any reason in particular, I just noticed it and was curious. | 20:21 |
| tomreyn | weird, my memory must be disintegrating. sorry. | 20:22 |
| filifunky | tomreyn if you're referring to a past issue I had, yep that's all fixed, I just needed to be on python3.8 for everything to work, so someone helped me learn the update alternatives stuff | 20:22 |
| filifunky | maybe If I switch back to python 2x I can see what's on my backup hard drive hmmm | 20:22 |
| leftyfb | filifunky: python has nothing to do with accessing your drive | 20:23 |
| filifunky | leftyfb yeah, didn't change anything | 20:24 |
| leftyfb | filifunky: login as root with: sudo su # then see if you can get in. If you can, then you just have permission/mount issues | 20:24 |
| filifunky | leftyfb: yeah I can get in either root or my normal username but once in and I ls, nothing shows up. Which obviously implies that everything in there disappeared. But when I try to click in there through the files app it says I don't have access...so it kind of gives me hope that I just don't know how to get in and really see what's in there...or there's something wrong that I'm missing | 20:25 |
| pymagic | has anyone coded an python-appindicator project in QT here on ubuntu? | 20:32 |
| pymagic | I could use some help | 20:32 |
| coconut | b1ack0p, sudo apt install xubuntu-desktop #would do that, but that would also make your desktop entries "not pretty" i would say. So you probably want to reinstall or dualboot. | 20:34 |
| filifunky | when I use df, there's clearly stuff in there | 20:39 |
| b1ack0p | coconut: i installed xfce successfully | 20:40 |
| b1ack0p | it has sweet old school look :p | 20:40 |
| b1ack0p | it is pretty for me lol | 20:40 |
| coconut | hope you like it! | 20:41 |
| filifunky | just had to unmount and re-mount whhooooohoooo | 20:41 |
| b1ack0p | yep | 20:42 |
| b1ack0p | now i better remove gnome :p | 20:56 |
| thawes | Can someone explain to me why, desktop files have to executable, even when they are in the XDG_DATA_DIRS path? I am trying to use desktop files generated by nix in ~/.nix-profile/share/applications. And (k)ubuntu refuses to run them because they are not "writable" | 20:56 |
| b1ack0p | i would like to keep gnome classic but if i remove gnome it will also go | 20:56 |
| b1ack0p | lets keep both for a while.. i can decide later | 20:56 |
| mra90 | how to connect to /dev/ttyUSB) with minicom? | 20:58 |
| mra90 | I try to do it by minicom -s | 20:59 |
| mra90 | and then in the config select that tty device | 20:59 |
| mra90 | but I cannot save the config | 20:59 |
| mra90 | "save setup as dfl" -> I get error message "cannot write to /etc/micom/minirc/dfl" | 21:00 |
| mra90 | what si wrong? | 21:00 |
| tomreyn | supposedly only root can write there (and you're not root), or the directory doesn't exist | 21:02 |
| mra90 | I am root | 21:02 |
| byroniac | I am groot :) | 21:03 |
| byroniac | sorry don't know but maybe someone else can answer | 21:04 |
| byroniac | Oh! /etc/micom or /etc/minicom ? Maybe you are trying /etc/micom and it doesn' | 21:05 |
| byroniac | maybe /etc/micom does not exist and that's what you are trying to write to? not sure | 21:05 |
| tomreyn | i believe this was a typo. on my 18.04 LTS system, minicom --help prints "The configuration directory for the access file and the configurations is compiled to /etc/minicom." | 21:07 |
| mra90 | in general how to initiate a connection to minicom? | 21:10 |
| mra90 | I mean from minicom to some tty device | 21:10 |
| Cknight70 | Does anyone know how to restart the Ubuntu server installer without rebooting the computer? I had to get my wifi drivers working first | 21:16 |
| tomreyn | Cknight70: i think if you just kill the subiquity process it should auto respawn. but there may also be a menu option for it if you hit escape (or some F key? F10?) | 21:18 |
| tomreyn | mra90: you need to create a customized configuration file or edit the default configuration, setting the serial port to the device you want to use. | 21:19 |
| tomreyn | if you created a custom configuration file you can just specify its 'file extension' (the part after the ., or what you chose to save it as) as an argument to "minicom" | 21:20 |
| tomreyn | !man | mra90 | 21:20 |
| ubottu | mra90: The "man" command brings up the Linux manual pages for the command you're interested in. Try "man intro" at the command line, or see https://help.ubuntu.com/community/UsingTheTerminal | Manpages online: http://manpages.ubuntu.com/ | 21:20 |
| cluelessperson | tomreyn, I want to thank you again. :) | 21:30 |
| cluelessperson | lowlatency kernel seemed to immediately help me | 21:30 |
| cluelessperson | and I dist-upgraded as well, together I've had no issues with slowdown at all. | 21:30 |
| cluelessperson | tomreyn, zero issues so far for hours. :D | 21:30 |
| ubuntuuser | how does one stop a command in progress? | 21:51 |

| wr | installed snap on a Debian, wanna fully remove it, how would remove core? | 23:29 |
| quadrathoch2 | wr it should be removable as long as you got no other snaps | 23:30 |
| wr | quadrathoch2, on my list only have, core 16-2.45.1 9436 latest canonical✓ core | 23:31 |
| quadrathoch2 | do you want to remove snapd completly? or just remove core? | 23:32 |
| wr | quadrathoch2, everything | 23:32 |
| quadrathoch2 | wr just remove snapd then | 23:34 |
| wr | quadrathoch2, when i do it i still have a directory /snap/ | 23:35 |
| wr | quadrathoch2, done this once, but now can't remember how removed it last time, i think i just issued snap remove core, but now fails | 23:36 |
| quadrathoch2 | wr if there is still a snap folder afterwars, just remove it after taht | 23:37 |
| wr | quadrathoch2, i had to issue same command snap remove core 3 times, and i had a broken status | 23:43 |
| quadrathoch2 | wr what error did it gave you ? | 23:44 |
| oerheks | wr, a good guide to remove snap and cruft, https://www.kevin-custer.com/blog/disabling-snaps-in-ubuntu-20-04/ | 23:44 |
| oerheks | if you were on ubuntu, i'd say change distro :-P | 23:44 |
| wr | oerheks, i read that link online already | 23:45 |
| quadrathoch2 | I'm not sure why somebody wants to install snapd on debian ^^ | 23:45 |
| wr | oerheks, like said Debian | 23:45 |
| oerheks | because snaps are fun | 23:45 |
| quadrathoch2 | oerheks i don't have anything against snaps, but there is probably a reason why he wants to remove it again | 23:46 |
| oerheks | quadrathoch2, yes, a valid question | 23:46 |
| Sven_vB | where can I read about the InputSource0 section of an AccountService user config in focal? | 23:47 |
| wr | oerheks, quadrathoch2 in my experience this fails a lot, but this is not Ubuntu | 23:47 |
| oerheks | i would like to see a software center, expandable with flatpack/appimage too... but there seems work in progress | 23:48 |
| quadrathoch2 | oerheks i mean isn't gnome-software just missing appimage? | 23:48 |
| quadrathoch2 | wr well what does fail mean in that regard | 23:49 |
| wr | quadrathoch2, i think i remove it now, sorry but i did a ctrl+l, when you install it on ubuntu you issue sudo apt install snapd? | 23:49 |
| wr | quadrathoch2, or you install it on su - | 23:50 |
| quadrathoch2 | wr on ubuntu it's preinstalled | 23:51 |
| wr | quadrathoch2, ah off course | 23:52 |
| oerheks | su - is the debian way, sudo -i for ubuntu, something with environment stuff | 23:52 |
| quadrathoch2 | oerheks debian moved also to sudo -i (or at least they changed the behavior) | 23:53 |
| wr | quadrathoch2, https://snapcraft.io/install/viber-unofficial/debian after i install it, how is it launched? i use xfce | 23:58 |
