[00:00] Hmm okay well i think i'll use kvm on my hpc server to isolate my boinc miner. And maybe virtualbox on my laptop for firefox. [00:01] htafdwes: if you're looking for desktop in VM, you might want to install from iso in one VM, make a snapshot, and then use that as the basis for your Ms [00:01] *VMs [00:01] Could stick my docker and maybe an lxc ontop of the lvm image since it'll get most of the cores. [00:02] Kvm* [00:03] htafdwes: yes, that's true, you can do tht [00:03] Nacc what version/distro would you recommend installing for the firefox vm? [00:05] htafdwes: dunno, it probably doesnt' matter to much, since firefox gets backported aiui [00:05] Like i want something with smallest possible footprint. Maybe just a firefox in an xinitrc? [00:05] htafdwes: at this point, i'd put it in an 18.04 VM [00:05] and you can pare that down as much or as little as you like [00:06] htafdwes: tbh, yes, you can do that. I think it's more work than it's worth. [00:06] htafdwes, How about docker containers? [00:07] jcdutton: for firefox? [00:07] htafdwes, yes. instead of a whole vm [00:08] Then have to do manual reaource isolation, at which point might as well just isolate the native firefox process, but that sounds like a lot of work. [00:08] i thougth docker had some support for this in the cli, too [00:08] but i might be wrong [00:09] htafdwes, that is all docker really is, just a way to isolate a process [00:10] https://github.com/jlesage/docker-firefox/blob/master/README.md [00:11] htafdwes: i mean, that goes back to my point, once you're running docker, you can use cgroups to isolate it however you want (e.g., cpu controller to restrict the scheduler, cpuset controller to restrict what cpus it runs, etc. Or docker might have APIs for it too [00:11] 'Browse to http://your-host-ip:5800 to access the Firefox GUI.' Lol [00:11] htafdwes: you can do that for *any* process on the system, docker is just a fancy wrapper around it [00:11] (well, not just, but you get the idea ;) [00:13] Hmmm k well i'll look into cgroups and cpuset [00:14] htafdwes: it's an interface that's worth understanding. There are also tools to wrap them so that you don't have to muck with echoing value manually, cgconfigparser, cgrules, cg{create,exec} [00:14] htafdwes: but it also helps to be sure you know what you want to achieve, which is usually more than half the battle [00:15] Well what i want to achieve is no crashing and better uptime [00:16] htafdwes: going back to my point earlier, afaict, even in a container, if firefox is crashing your host kernel, it doesn't really matter if it's resources are isolated (unless it's a memory leak somewhere and you are able to mitigate it by limiting it. You're still not fixing the issue you're just avoiding it. [00:16] Simplest choice (tbh), seems to be run firefox in a VM and see why it crashes, if it does [00:16] htafdwes: it's very strange that your system crashes due to firefox, imo [00:16] htafdwes: you have swap enabled, right? [00:17] htafdwes: you coudl also just limit firefox's memory using the memory cgroup [00:17] i have swap enabled and 8GB ram on my laptop [00:18] Hi anyone can help me with Chroot [00:19] htafdwes: hrm, i was going to guess a memory leak, but you'd be able to detect that with swap [00:19] powerninja: ask your question, not ask to ask [00:20] It usually happens when loading a website. How would i detect it with swap? [00:21] htafdwes: i meant you'd see swap getting used [00:21] Ah, well when it crashes can't really check anything. [00:21] htafdwes: right, i get it [00:22] htafdwes: the problem is, i'd expect your crashes will be not reproducible in the VM ) [00:22] you could try disabling some extensions, or anything not standard [00:23] Ubuntu 1804.1 I installed Bungie and the bootloader to sda..Ubuntu 18.04 ended up in the fourth position on the grub menu..Changed /etc/default/grub..default to 4 and ran update grub no change in grub menu [00:24] Whats a good cgroups tutorial for ubuntu? [00:24] Should I have made the change in Bungie [00:24] Nacc hmm well i guess will see. If it doesn't crash in vm then so much the better. [00:26] how do i install redis with apt-get? [00:27] Hmm i found this one: could try it. [00:27] https://www.cloudsigma.com/howto-cgroups/ [00:30] nacc: yeah i've tried disabling extensions, but then i end up adding them again. I just dislike that processes are allowed to crash the system like that. If there was some kind of 'process police' that would batton or jail a process that is taking more than it's fair share of resources for too long would probably be ideal. [00:32] htafdwes: right, the problem is it's not clear what's crashing or why [00:32] djapo: ' sudo apt update ; sudo apt upgrade ; sudp apt install redis ' redis is in the universe repo . [00:33] sudp/sudo* [00:43] nacc: yeah, if cgroups doesn't work, then I'll stick it in a VM. [00:59] Bashing-om: i can't install it .. im on a ubuntu aws instance how do i add the universe repo [01:00] 'universe' distribution component is already enabled for all sources.

[01:14] Bashing-om: it works, its basically the same [01:19] djapo: :) you do good work :) [01:21] okay, that's weird, it looks like ubuntu doesn't have support for cgroup configuration [01:22] at boot * [01:22] apparently it was taken out in 13.04, and nobody bothered adding it back. there are just some workaround hacks.

[03:34] Lvl4Sword: gnome-screensaver-command is in the package gnome-screensaver, which isn't installed by default in 18.04 [03:34] lotuspsychje, Well, it's not for me it's for someone else and it's related to Linux Mint. Supposedly /usr/bin lacks any *-screensaver-command [03:34] dax, Ah, what is installed by default? [03:34] and linux mint support goes in the linux mint channels [03:35] Well, seeing as latest Mint stems from 18.04, figured I'd go to the source. [03:35] the source's /topic is quite clear ;) [03:36] and besides, desktop environment stuff like screensaver packages tends to vary from distro to distro [03:36] as far as ubuntu 18.04 goes, i don't think there is a screensaver program installed by default any more, though i could be wrong [03:37] Hmm. I'll need to load it up on a vm it sounds like. [03:37] dax: correct, i have xscreensaver installed optional here, it does not interfere with gnome screensaver anymore [03:37] as gnome screensaver isnt by default anymore [03:38] Interesting. I'll certainly have to poke around [04:02] Hi friends, im trying to install older php version on my ubuntu but i cant when i do apt-get install php, in my repositories i get the 7, and i have problems with 7 version in my ubuntu, how can i install older version in my ubuntu? is there a way to add the older version in my repositories?

[07:20] @lotus|NUC, window theme: ambiance, gtk-theme: flatabulous [07:21] empedokles78: can you try setting another theme, then make your flat theme active again? [07:24] @lotus|NUC, do you only mean the gtk theme? [07:25] yes [07:27] @lotus|NUC, seems to work I see buttons again and the window close buttons are on the left hand side. [07:27] !yay | empedokles78 [07:27] empedokles78: Glad you made it! :-) [07:29] ubottu, is there a way to disable that animation for the dash-search?

[07:39] empedokles78: wich animation exactly? [07:40] lotus|NUC, if you click on show apps in the sidebar there is some animation of app icons. [07:43] empedokles78: can you find some settings in unity-tweak-tool? [07:44] empedokles78: general/windows animations off is that what you mean? [07:46] lotus|NUC, it's not that setting, the apps are popping up. I don't think it's a window anim. Also: Isn't unity history with 18.04 LTS? === mar77i_ is now known as mar77i [07:52] empedokles78: unity is now a community item, i did not test myself on 18.04 === imsurit_ofc1 is now known as imsurit_ofc [07:53] lotus|NUC, I thought 18.04 is using only gnome? [07:55] empedokles78: no, flavors and DE's and WM are choosable [07:56] empedokles78: by default 18.04 desktop uses gnome yes [07:56] empedokles78: but for example the 16.04 users that chosen to lts upgrade have also the unity choosable in 18.04 [07:59] lotus|NUC, I see, makes sense to stick with it then. [08:02] empedokles78: that depends what you want, you can choose gnome from the login screen aswell if you like, canonical did their best to make it unity-like too [08:07] lotus|NUC, I guess unity will not be developed anymore in future versions? [08:08] I have some software called yEd graph editor under apps and don't see a way to remove it, it seems not to be installed via apt.

[09:01] gpunk: It [09:01] Sorry, a few years old [09:01] It [09:01] It's a new computer [09:02] But the keyboard has been working since yesterday?? [09:02] esomir: tried anotehr usb port? [09:02] blackflow: Yeah, I've tried every USB port [09:02] Also the one my mouse it attached (and working) to [09:03] I have two versions of inkscape, one from ubuntu 18.04 and one installed over a snap. How can I remove only the snap one? [09:04] With the ubdate to 18.04 they have the same version number .92 3 [09:05] esomir: try it thru a usb hub if it doesnt wotk still, it might have died [09:05] empedokles78: 'sudo snap remove inkscape' === amosbird_ is now known as amosbird [09:07] gpunk: Just tried attaching it to my Mac. that worked fine [09:07] So the keyboard works [09:07] good [09:09] But I just don't know why it suddenly stopped working [09:10] Is the driver corrupt or something? [09:10] esomir: probably not, there would be entries in dmesg if the kernel found an error. [09:10] i'd reboot again ... [09:10] esomir: I'd suspect electrical failure on the kbd. am I understanding you correctly that it stopped working mid-operation? did it work again after re-plugging? [09:11] blackflow: It worked before I rebooted, then I rebooted and it didn't work there [09:11] It works in the bios, btw [09:11] And works on my Mac as well [09:11] So I don [09:12] dont think it's a failure on the keyboard [09:12] But what does the "no configuration chosen from 0 choices" mean? that it cannot find a proper driver for it? [09:12] esomir: hm, wait, there _is_ something in the dmesg, line #3 [09:13] blackflow: Hmm [09:14] I'll just try rebooting, blackflow / gpunk . BRB [09:21] working? [09:21] Nope, not at all [09:21] It works in the bios [09:21] I even tried booting with an older kernel [09:21] I'm running 16.04 btw [09:22] esomir: usb keyboard? [09:22] esomir: I wonder if it's a DE (mis)config. Does it work under another TTY?

[09:32] esomir: I'd reboot into text console (so no DE loading up) and see if it works there. Do you know how to _temporarily_ edit kernel command line in grub? So you add "3" at the end of it (without quotes) and boot into non-graphical env [09:32] lotus|NUC: thx, I will try it tonight. so it's not supported? [09:32] lotus|NUC: it's not out of the box, you have to do some "hacking" to get it to work [09:33] Hmm I'mm try booting into a console [09:33] brb [09:34] lotus|NUC: ok thx, i'll check it out tonight, too bad, it worked so well with fakeraid 0 for about 2 years [09:37] Okay, so even if I start into recovery mode with a console, it fails with the same error "unable to read config index 0" [09:38] It just doesn't make sense for me, as it has been working previously === esomir_ is now known as esomir [09:40] I was just wondering why fake raid stopped working after +- 1 years.

[11:47] hi [11:47] anyone know if there's a way to make wget write the data to disk only on completion? [11:47] that is, to avoid writing partial data to disk [11:52] pokmo Well you can try with resume option to complete the incomplete transfers [11:53] kundancool sure, but i don't think i'll resume them. i just want them not stored on disk [11:53] hello, what's the goal of docker.io in multiverse compared to docker-ce from docker.com? [11:53] I don't understand why it's here and what it's for [11:55] pokmo I assume you have a list of files you are downloading you can script it to a function which downloads file with .tmp extension and then renames when download is complete else after things [11:55] after list ends it cleans up .tmp files [11:55] kundancool yeah, i guess i'll have to do it manually [11:55] which the best you can do for that [11:57] pokmo, or a C routine + curl to store the data in a buffer; if the buffer matches the file 's size (or other condition) ; write to disk [11:58] ioria sure. i just thought wget got a way to keep intermediate download in its own buffer === kundancool is now known as anonymousK [12:00] pokmo, https://unix.stackexchange.com/questions/149521/wget-internal-buffer-size ; for Curl solution https://curl.haxx.se/libcurl/c/getinmemory.html [12:01] thanks [12:02] gl === anonymousK is now known as kundancool [12:14] Hi [12:22] Howdy folks [12:44] Hello. I've never used LVM before. If I want to start fresh with an unused drive (not for the OS itself), I just create an LVM partition on it and take care of subdiving later, right? And GPT is out of the picture if I use LVM? [12:52] adrian_1908: LVM and GPT are not mutually exclusive. I suppose what oyu need here is a GPT partition you would use as a LVM "pv" (physical volume) atop of which you create volume groups and logical volumes [12:55] blackflow: ah ok, so GPT is still needed to make the drive "visible" as ready to be used for LVM? [12:58] I think I got confused in that one can also create a physical LVM volume on an unformatted drive. But this is said to have potential drawbacks, so I'll go with the GPT -> LVM route then. === Richard is now known as Guest70690 [13:02] adrian_1908: LVM has 3 levels: physical volume, volume group and logical volume. PVs are made of physical devices, disks. VGs are made of one or more PVs. LVs are subdivisions of VGs. as a PV you can use whole disk or a partition, or any _block_ device. [13:03] adrian_1908: if you don't boot from that disk, you can use the entire drive as PV. otherwise you might need at least bios_boot and a /boot partition [13:03] (though lately I hear grub can work out LVM so it doesn't need a separate /boot -- no personal experience with that. I'd still use separate /boot tho'. it's cleaner) [13:04] s/bios_boot/bios_grub/ [13:05] Got it, thanks. [13:12] Hey, bit if a noob question... but how do I back up my lubuntu in it's current form? I've spent so much time configuring it to work correctly with my laptop and jenky hardware, that I'd hate to figure out how to do it all again if something happened [13:13] Is there a way to back it up as an image with all the scripts and software I already have installed? [13:16] Galactor: you can create an image of it with Clonezilla [13:17] or dd [13:18] BluesKaj: not a good idea to use dd to do that on a live system though, hence my suggestion [13:18] I'll give it a peak. Thanks Shabbysheik and BluesKaj ! [13:18] memory lane [13:19] Shabbysheik, I copied my / and /home partitions to an outboard drive without incident with dd === Class7_ is now known as Class7 [13:23] BluesKaj: yes it will copy them, but anything that is modified during the copy process will be corrupted as dd works at the bit level. That is a good way to have a corrupted backup. Best practice is to boot to a proper cloning tool like Clonezilla [13:24] Shabbysheik, one just has to make sure the targets are unmounted to make the system bootable [13:24] before coipying [13:26] I know dd's risky, and clonezilla is definitely a good option as well [13:34] Hello guys, I have installed windows 10 on another partition and now the grub boot loader seems to be gone [13:35] how can I install it [13:36] morphyeys: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows [13:37] morphyeys: first result on google for "ubuntu restore grub" [13:37] hehe nice [13:37] thank you very much === kundancool is now known as anonymousK [13:56] Why did my 18.04 LTS upgrade install remmima remote desktop? [13:56] empedokles78: because it's part of the install/release? Just remove it if you don't want it. [13:57] leftyfb, okay, I guess it's a security risk. [13:57] empedokles78: why is a remote desktop client a security risk? [13:58] empedokles78: no it won't just use that, I think I seen that be installed before myself too or something similar [13:58] empedokles78: anything that s put there by default is generally fine [13:59] okay, I'll remove it. [13:59] empedokles78: what makes you believe an RDP/VPN client being installed as part of the release is a security risk? Do you believe Firefox being installed is a security risk as well? [14:01] Maybe if someone uses firefox to do evil things. But I have to live with that. [14:02] empedokles78: With that mentality, you shouldn't be installing anything on your computer if you want it that secure. Just leave it off and unplugged. [14:05] I have no need for it, so the less software the better I guess. [14:06] empedokles78: That doesn't make it a security risk === semeion is now known as mnemonic [14:10] If someone is using my machine as a zombie anything can become an issue. [14:11] empedokles78: not as likely with Linux as Windows [14:11] by far [14:12] sebsebseb: lets not [14:13] leftyfb: no that's not Windows hate or dislike, that's the truth, most botnet zombie pc's are run by WIndows ! [14:13] empedokles78: If someone is "using your machine as a zombie" any application you have installed is 100% irrelevant to what that person is capable of doing with youe machine. [14:13] sebsebseb, yes hopefully. [14:14] why irrelevant? [14:19] empedokles78: because if you've been compromised, all bets are off. You have zero control over anything and the exploiter has 100% control and can install and do anything they want. Regardless of the state of your machine. [14:19] leftyfb: empedokles78 even Intel had some hardware security issues with the cpu recently :d he h h eh [14:19] and things like that [14:20] ok, feel free to take this verymuch pointless discussion to #security or #ubuntu-offtopic [14:37] sebsebseb, I'm on intel. :) [14:40] did I ? ;) === Richard is now known as Guest24765 [15:32] once again trying to install bionic amd64. mkfs fails: "partman: /dev/sda5 is apparently in use by the system; will not make a filesystem here!" but "mount | grep sda" finds nothing. any ideas? [15:34] Sven_vB: can you pastebin `parted /dev/sda unit mib print` ? [15:35] for copying artifact over rsync, is it mandatory to have the -a flag? [15:35] blackflow, I could. do you need all of it or just " 5 2.00MiB 15362MiB 15360MiB logical ext3"? [15:36] dwg_: artifact? [15:36] Sven_vB: I was interested in type and fs of sda5 [15:36] leftyfb: yeah.. something like a .tgz file or a .rar file? [15:37] blackflow, "mke2fs 1.44.1 (24-Mar-2018)¶/dev/sda5 contains a ext3 file system¶ last mounted on /target on Tue Sep 25 04:30:42 2018" [15:37] Sven_vB: are you installing multi boot or will use the entire disk for hte new installation? [15:37] blackflow, custom partitioning ("something else") [15:38] dwg_: ok, you mean archive. As in a compressed file. -a is a whole bunch of parameters in one. You should look at the man page [15:38] leftyfb: sry my bad [15:38] yes [15:38] Sven_vB: is sda5 the last partition on the disk (by byte offset)? [15:38] blackflow, nope, there are at least 10 partitions [15:38] Sven_vB: also stupid question, did you try to umount it? [15:39] Sven_vB: why do you need so many partitions? [15:39] maybe some overzealous gnome automounter process saw it and mounted it [15:39] blackflow, not by its own name. I umounted /target recursively, but I'll try explicitly umounting sda5. [15:40] leftyfb, it helps me keep track of how much of which kinds of litter I accumulate. :) [15:41] blackflow, umount: /dev/sda5: not mounted. [15:41] Sven_vB: sounds like you're only making more work for yourself [15:41] for little, to no benefit [15:41] Sven_vB: pastebin the output of `mount` pls (as root) [15:44] blackflow, actually I'll debug that myself first. there's lots of unrelated disks mounted that shouldn't be. === Apachez- is now known as Apachez [15:47] leftyfb, might be just nostalgia. main benefit probably is that I can postpone learning about better quota methods. :D [15:48] Sven_vB: I was thinking it got picked up via some uuid, label, gvfs, something and not directly grepable as "sda" [15:48] blackflow, good call, I'll check that. [15:49] Sven_vB: this day and age, people typically have storage that it well beyond what is necessary and won't come close to running out of space. Unless you do something silly like make a separate /boot with inadequate space. Or at all. [15:51] leftyfb, the huge availability of storage is one of the reasons I impose limits on myself, otherwise I tend to collect stuff way beyond my ability to manage it. [15:57] blackflow, there's indeed a gvfs that lsof cannot access. maybe something broke when ubiquity crashed earlier. I'll just reboot and hope that fixes it. === SimonNL is now known as SimonNL_Afk === BenderRo- is now known as BenderRodriguez [16:02] j #security [16:05] is there a way to install spotify without snap?
