[00:00] j0h: none at all unless you've got an IPv4 address hard-code in the kernel command-line or someplace else [00:01] nope, nothing like that [00:02] it says on that article "The default kernel’s behavior is getting the IP address via dhcp (ip=dhcp). " [00:02] j0h: well this'll be your problem; if you manually do "dhclient&" to run it in the background it'll by default try IPv4, then run your script and it'll likely all work, which will prove the problem is the missing dhclient call [00:02] hey guys. Im having trouble logging in. I set the machine not to ask for password on login and now it does. And the proper password doesnt work. I can ssh in from another machine onthe local network though. [00:02] j0h: what *is* on the kernel command-line? [00:03] Ubuntu Server 18.04, DNS resolution fails after uninstalling PiHole. Manually editing /etc/resolv.conf fixes it, but it doesn't persist after reboot. Manually editing /etc/netplan/foo.yaml seems to work, in that netplan doesn't give any errors when applying, but it doesn't fix my DNS resolution problem. What is the correct way to commit changes to /etc/resolv.conf ? [00:03] I didn't put anything on the kernel command-line because it said that was default [00:03] .xsession-errors doesnt show anything and I removed .Xauthority and rebooted just for good measure. still no joy [00:03] so I skipped that step TJ- as I didn't need to assign a static ip [00:04] TJ-, this is a read only right? I'm not able to disable this script from running through the initramfs shell? [00:05] just to revert all the reverse ssh stuff and see if it does get ip without it [00:06] j0h: I'm searching the kernel source to check on the autoconfig/DHCP internal stuff [00:07] ahh ok [00:07] also, I just noticed that the ping would always fail because my external server doesn't respond to pings [00:07] -.- great >.> [00:07] I should have checked that, silly me [00:09] TJ-, that is likely what the delay is [00:09] good old azure blocking ICMP [00:09] j0h: hmmm, but is that affecting the DHCP too? [00:10] hum, I don't think that would [00:10] like, the script will reboot after 60s if it doesn't get a ping right? [00:12] j0h: kernel-wise, it has the config flag CONFIG_IP_PNP_DHCP but that isn't set in the Ubuntu builds; check with "grep -n CONFIG_IP_PNP_DHCP /boot/config*" [00:13] sorry TJ, got disconnected, I'm still trying to get into the normal boot somehow [00:13] so I can disable this script and start again -.- [00:13] what regex do i use if i want to grep for subdomains from a text file [00:14] any ideas for a login loop on 19.04 ? [00:15] j0h: so, I'd try adding "ip=dhcp" to the kernel command line [00:16] is this through grub e again? [00:17] j0h: you need to be aware that all this internal kernel network support is *only* to allow it to mount its root file-system from an NFS Server, and so when those NFS facilities aren't built in, this IP autoconfigure behaviour won't work. I'm not seeing signs of its config options in the Ubuntu kernel configs but I was pretty sure they are there somewhere! [00:18] j0h: yes, always, only way to add it at boot-time [00:18] j0h: once the system has fully booted you can always edit /etc/default/grub to add it to GRUB_CMDLINE_LINUX= and then do "update-grub" so it happens automatically [00:19] ahh ok, the only issue I see TJ- is that this script will fail because of the sleep /sbin [00:19] as that doesn't persist when I do ln -s [00:20] there must be some magic that caused it to get an IP without setting GRUB_CMDLINE_LINUX, but I'll be sure to do that when I manage to boot [00:20] how do i grep only the subdomains in this text file https://ibb.co/YLHRC70 [00:20] j0h: the full details of that network functionality is here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/filesystems/nfs/nfsroot.txt [00:22] gotcha, will read through that [00:23] What could be the reason, why I, being _root_, can not edit files in /snap/wekan ? [00:23] I seem to have insufficient permissions [00:23] the files seem to be owned by "root" [00:23] TJ- is there a way to persist the ln -s for /bin/sleep here? [00:24] so that I can try adding ip=dhcp to kernel [00:24] and see if it boots [00:24] Rojola2: snaps are stored in squashfs filesystems, which cannot be written to [00:25] thank you sarnold [00:25] sarnold, is there any workaround? [00:25] I must really edit a file [00:25] Rojola2: I don't know what problem you're trying to solve [00:25] sarnold, I try to edit a template file [00:26] /snap/wekan/550/programs/web.browser/head.html [00:26] ^ this is the file I must edit [00:26] Rojola2: the filesystem is read-only [00:27] Rojola2: if whoever packaged it has given you the sources, you can change the file and then rebuild the snap [00:27] TJ-, on /scripts/dropbear, there is configure_networking [00:27] I think this might be what brings the connection ip [00:27] can I unmount the snap, mount it in write-mode, edit it, and remount it? [00:27] I am not used to not being allowed to edit a file on linux [00:28] in the past, I also installed it via snap and I could edit this file [00:28] nah maybe that was a *.deb back then [00:28] Rojola2: probably not. you can certainly use unsquashfs to unpack the thing, edit it, then mksquashfs to repack it, but that will change the filesystem, and probably snapd will refuse to work with a corrupted filesystem image [00:29] Rojola2: it'd be significantly easier to get the source code and change it then rebuild the image [00:29] installing this without snap is difficult [00:29] snap made it so easy [00:30] ask whoever packaged it if the sources are available; it might be as easy as git clone ... ; cd ... ; vim foo/head.html ; snapcraft [00:30] j0h: that is likely; I just found the 'knob' that controls kernel networking, it's CONFIG_IP_PNP and it isn't set in the Ubuntu kernels [00:31] TJ- /debian/initramfs/dropbear-hook [00:31] that's where the dropbear hook is on the git [00:32] sarnold, thank you! [00:32] Rojola2: all sorted? :) [00:33] TJ- is there something that I can do to disable this script from running? [00:33] I actually can't see myself booting into normal [00:34] can I simply do rm link-with.server.sh? [00:34] j0h: configure_networking() is provided by initramfs-tools /usr/share/initramfs-tools/scripts/functions [00:34] the dropbear prehook calls that function [00:36] I [00:36] sarnold, no [00:37] I just want to disable this reverse ssh script now form initramfs, is there anything I can do to boot locally TJ-? [00:37] sarnold, I will probably reinstall wekan via "sandstorm" so I can edit it [00:37] still login looping. lightdm.conf reports that I should still be on auto-login. AM I going to have to reinstall here? [00:38] mwm_ did you try startx? [00:39] tonyt: startx wont work. the machine is my NAS (and other stuff ) rig so I run itheadless over the network. Only access I have right now is ssh (normally use teamviewer) [00:40] Rojola1: dang. I hoped you'd gotten it going; snap sounds really easy to use, but two minutes did seem too good to be true, haha [00:41] it just started wanting a password after the last reboot. when I put the proper password in it just loops back to the login prompt [00:42] j0h: from the host remove its executable bit: "chmod -x /etc/initramfs-tools/scripts/init-premount/link-with-server.sh" [00:43] j0h: that way when the initrd is rebuilt it won't be executed on boot [00:43] j0h: whilst you're testing that script you ought to add a flag that stops it acting [00:44] where do you add the flag TJ-? [00:44] I should just tested this in a VM first [00:45] oh and thanks TJ-, I just managed to boot into the main os [00:45] pheww! [00:46] j0h: I'd add a line before the ". /scripts/functions" with "if grep -q dbclient=no /proc/cmdline; then exit 0; fi" [00:46] j0h: with that line, to disable the script, you'd just need to add "dbclient=no" on the kernel command-line at boot-time [00:46] j0h: of course, don't forget to make the script executable again if you adopt that! [00:46] awesome, thanks TJ- [00:47] I won't keep you up any longer! [00:47] j0h: I was about tosay I have to go; got to be up in 3 hours! [00:47] gosh! [00:47] hope you managed to some sleep, sorry for keeping you up so late [00:47] you've helped me loads! appreciate it! [00:48] night night [00:48] yeah.. got a large summerhouse construction delivery to supervise and the construction crew are due to arrive around 7am [00:48] early doors :o [00:49] j0h: hope you get it sorted; might help to let the writer of that script know about the things they missed that broke it too [00:49] yea, I'll create a PR when I figure it all out === DetectiveTaco is now known as DetectiveBoobies === DetectiveBoobies is now known as DetectiveTaco [01:06] Looking for some help diagnosing/fixing: I upgraded to 19.04, now my computer wont detect my keyboard/mouse through my KVM. the boot log said something about a usb error or bad cable, however I've tried changing the cable and it also works with the other machine connected to the kvm switch.

Do you have PPAs? [02:20] 18.04. tried updating some dependencies a newer version of a package required [02:20] no PPAs, just downloaded the .deb files [02:20] Oh, yeah manually installing .debs that conflict with existing ones is a bad idea [02:21] Joah, can you try 'apt install --reinstall ' [02:21] good idea [02:23] https://paste.ubuntu.com/p/JSrMf35Jw7/ [02:23] that's what i get D: [02:23] i don't even know where to start [02:23] Joah, did you try to install a newer libc6? [02:23] yeah [02:23] bad idea, i guess [02:24] lol [02:26] very [02:26] You might be able to find the previous .deb in the cache and install it? But honestly I'd reinstall [02:26] i have the .deb files [02:27] i'll paste what it does when i do `dpkg -i` [02:27] https://paste.ubuntu.com/p/5bMzwN999T/ [02:28] Yeah, this is beyond me, sorry. [02:29] no problem, thanks for the help! [02:29] anyone else have any ideas? [02:35] Joah: *maybe* a do-release-upgrade. Maybe you can drag the whole thing forward. maybe it won't even touch it.. [02:35] Joah: if you want to try the downgrade instead, for this most recent pastebin.. [02:36] Joah: dpkg -S /usr/share/doc/libc6/NEWS.gz to find all the packages that package that file, and make sure to change all of those packages to a version with the identical version of that file [02:37] so i would change /usr/share/doc/libc6/NEWS.gz to the older version manually? [02:39] no, you'd find all the packages that dpkg says own that file, and you'd downgrade them all at once [02:39] ah! [02:39] so sorry for the noob question, but what command would i run to downgrade them all at once? [02:39] libc6:i386, libc6:amd64: /usr/share/doc/libc6/NEWS.gz [02:39] that's what it gave me [02:40] I think apt-get install ./path/to/old/libc6... ./path/to/old/libc6.i386.deb.. [02:42] sarnold, that gives me this: https://paste.ubuntu.com/p/gNz6fWHS2x/ [02:42] it looks like libc6 is the issue. is there any way to force that specific package to reinstall, i guess? [02:43] Joah: try adding in paths for the older versions of libc-bin, libc-bin-dev, libc6-dev, libc6-dbg etc [02:45] depending upon how well your system is working, maybe just apt-get install libc6=2.27-3ubuntu1 libc-bin=2.27-3ubuntu1 libc-dev-bin=2.27-3ubuntu1 locales=2.27-3ubuntu1 libc6:i386=2.27-3ubuntu1 libc6-dbg=2.27-3ubuntu1 libc6-dev=2.27-3ubuntu1 [02:52] sarnold, that almost worked [02:52] it gave me the NEWS.gz error [02:53] Joah: where it says "which is different from other instances of package" what packages are listed there? [02:53] trying to overwrite shared '/usr/share/doc/libc6/NEWS.gz', which is different from other instances of package libc6:amd64 [02:54] try adding libc6:amd64=2.27-3ubuntu1 to the long command line [02:54] same error [02:55] should i try manually replacing NEWS.gz? [02:55] dang. no, I don't think that would move you forward [02:56] it did [02:56] trying to overwrite shared '/usr/share/doc/libc6/changelog.Debian.gz', which is different from other instances of package libc6:amd64 [02:56] woah really [02:56] yeah [02:56] alright, keep going then :D [02:56] weirdly enough [02:56] not at all what I expected [03:00] is it possible to run private internet access on a ubuntu server 18.04? [03:02] sarnold, well [03:02] i got a lot further [03:03] now i gave me this: https://paste.ubuntu.com/p/sjqjJqtk5z/ [03:03] Joah: I've *never* seen that one. wow. [03:03] however [03:03] when re-running the command you gave me [03:03] Joah: run the command again? see if it says the same thing>? [03:03] https://paste.ubuntu.com/p/srPN7fc2gF/ [03:04] YESYESYESY [03:04] Joah: awesome :D [03:04] thank you so much, man [03:04] you're a lifesaver [03:04] you're probably not quite done [03:04] try an apt-get install -f [03:04] yup [03:04] no issues [03:04] dude [03:04] well done [03:04] i'm worried that something else is broken, though [03:05] maybe debsums -sa ? [03:05] lordcirth_: find anything? [03:06] sarnold, only one issue with chrome [03:06] so i should be good, right? [03:06] Delphin, wasn't really looking, no. [03:06] Joah: yeah, sounds good to me :) [03:07] thanks again, sarnold [03:07] i'm gonna reboot [03:07] good luck, hope we're right :D [03:07] if i'm not back in a few... r.i.p. this install [03:12] :D [03:13] Fix one thing and another issue pops up...

[04:20] Gallomimia: hmm strange laptop is heating up and still fan not working, there must be fan issue or something [04:20] it's a desktop [04:20] the fan is running again. the temperature readings look normal [04:21] Gallomimia: Doesnt matter I think latest systems comes with automatic fan on smps and cpu [04:28] this board is i think 4 years old [04:28] the fan control is part of the bios/efi [04:30] Gallomimia: if the fan is not working at all you can check with alternate power supply I am no hardware expert but I had similar issue with an old board [04:30] Lucky for me that was a faulty fan [04:30] it's working now. i'm not even sure if it was simply a faulty readout on the sensors [04:31] the cpu temp was reading at 15 and 18C which is pretty much impossible too [04:31] ambient is warmer than that. there's no way it could be colder [04:32] reboot was a wise thing to do. i'm just left wondering what was up after waking from suspend/sleep [04:32] Try burn the cpu with some bench tools and see temp variations [04:33] it's not the same kind of suspend i think. it has to be some kind of hardware thing. and this motherboard is just not a friend for linux based OS [04:34] grief at every step. and to make matters worse i have a pair of EVO840's for some speediness. complete with firmware bugs. they don't have any non-windows updaters big thanks samsung. and even so i have read that the firmware updates make the issue worse, not better [04:35] i'm never giving that company another dime. i have used their full range of products and... just, puke.

Can i safely assumed that all IP's starting with 192.168.x are localhost ? [05:34] johnc--: yes and no. Yes, 192.168.0.0/16 range is so called "non-routable", RFC 1918 range, so public routers _probably_ won't ever know how to route that. no, ICANN has nothing to do with "localhost" name, and public DNS services will often add a record for "localhost" if you query them directly. I doubt it'd ever go through root DNS servers. [05:38] johnc--: also "localhost" is traditionally 127.0.0.1, not 192.168.0.0/16, and some would say teh entire /24, /16 or even /8 range of that subnet, and by default set via /etc/hosts of pretty much every distro.

[09:01] sombody* [09:01] somebody* [09:01] typing is hard [09:01] !wsl [09:01] Windows 10 has a feature called Windows Subsystem for Linux, which allows it to run Ubuntu (and other Linux distro) userspace programs without porting/recompliation. For discussion and support, see #ubuntu-on-windows or ##windows. For installation instructions, see https://msdn.microsoft.com/en-us/commandline/wsl/install_guide [09:03] I do not need installation instruction, just have other question, but I will go to correct channel [09:04] nonamme: "For discussion and support, see ...." [09:05] hello. is the usb-creator-gtk thing legacy now? It doesn't let you select ISOs, so maybe there's a different way [09:05] blackflow: ? [09:06] nonamme: what bot posted is not just about installation instructions. re-read teh part that starts with "For discussion and support, ..." [09:06] blackflow: what did I write at 10:03:53 ? re-read it [09:07] what timezone? [09:07] GMT 00:00 [09:08] nonamme: great. then you know what to do ;) [09:08] blackflow: :* [09:10] LACampbell: what are you trying to create, there might be an easier way [09:11] hi EriC^^ . just a bootable usb stick. also tried downloading unetbootin but the PPA is bad. not my day today [09:11] anyway just want to know if usb-creator is still the preferred way before I spend an hour googling [09:13] Hi all how to set up permissions for ntfs file system so it will mount [09:13] LACampbell: have you considered using dd to make the bootable usb? [09:20] Hey, a quick question. When I want to uninstall mate-dictionary from the mate-utils bundle, do I have to remove the whole bundle and reinstall the packages I want? === Soni|AntiMatrix is now known as Soni [09:28] Hi folks [09:29] How can I pass an environment variable to a program that is running with sudo? [09:30] acebrianjuan: sudo program ENV_VARIABLE_NAME [09:30] I'd like to keep the nominal value of the OMP_NUM_THREADS env variable [09:30] Hello - just did an install of Lubuntu 18.04 LTS on an eeePC with LUKS. When I boot the LUKS password prompt and the Lubuntu logo behind are very dim. I can use the adjust dimness key to change this, ut I don't get why this is even then. If I do nothing and enter the password, it autmatically continues the boot process and the dimness is resolved. How can I make the default LUKS prompt brightness correct permanently? Thanks. [09:30] nonamme: that simple? [09:31] acebrianjuan: yes [09:32] acebrianjuan: but you need to add $VAR_NAME [09:32] I missed $ [09:36] nonamme: so if I do: sudo program $OMP_NUM_THREADS=1 this should do? [09:37] Would it be better to ask in #Lubuntu? [09:38] acebrianjuan: `sudo --preserve-env=OMP_NUM_THREADS {command}` or `sudo OMP_NUM_THREADS=$OMP_NUM_THREADS {command}` (the second one is rather ugly IMHO) [09:38] acebrianjuan: so if you want to pass '1' to your program just pass 1 [09:39] acebrianjuan: but if you want pass $VARIABLE just sudo program $VARIABLE [09:39] acebrianjuan: sudo program 1 [09:39] nonamme: I think they want to pass an environment variable, not a command line argument [09:40] nonamme: no, I need to preserve the env variable as ayekat said [09:40] ayekat: thank you [09:40] ayekat: thanks, missunderstand [09:41] no problem [09:44] hi all you good people.. [09:44] how can i get a snap to acces usb webcam ? [09:45] ( snapcraft - scratux for school ) [09:48] ayekat: I am getting the error '--preserve-env' doesn't allow an argument [09:49] acebrianjuan: hmm... lemme check if that was a recent addition [09:51] acebrianjuan: ah yes, it appears that --preserve-env=[…] was only added recently (according to https://manpages.debian.org/testing/sudo/sudo.8.en.html, 1.8.19 doesn't have it, but 1.8.27 does) [09:51] acebrianjuan: what version does `sudo --version` show? [09:52] ayekat: 1.8.10p3 [09:52] ayekat: I am reading the man page for sudo [09:53] well, then I guess you'll have to go with the `sudo ENV={value} {command}` syntax for now [09:53] the --preserve-env option does not require an argument indeed [09:53] it keeps all the env-variables [09:53] acebrianjuan: but... 1.8.10p3 - what version of ubuntu is that? ^^ according to https://packages.ubuntu.com/search?keywords=sudo, even 16.04 already has 1.8.16 [09:54] acebrianjuan: yes, but on more recent versions, it takes an optional parameter, where you list the envvars you want to keep [09:54] acebrianjuan: see the man page I linked above [09:54] ayekat: Ubuntu 16.04 [09:55] maybe I need to run an upgrade soon [09:55] ayekat: thanks for the help mate [09:56] you're welcome [10:24] How to resolve brightness issue at boot?

[10:49] b1ack0p: Yes I did that on 16.04 i forgot but Its was fixed for me but never tried after upgrade [10:49] hello. with certain mkv vids the gpu temp rockets up [10:49] until the system shuts down [10:49] ok let me try [10:50]
