tomreynoh /boot/efi on a supposedly bios booting system00:00
leftyfbit's because he installed grub when chrooted from an EFI system (/sys/firmware/efi existed)00:01
tomreynthat must have been a different time than when grub said "installing for i386-pc platform", though00:03
gmcastilyeah i'm confused - i think i just need two references in there - one to /dev/sda1 on /boot and one to /dev/sda2 on / and thats it00:06
gmcastilthere is an efi directory in /boot now00:07
gmcastili'm guessing ubuntu tried to create one in order to mount what it thought needed to be there?00:07
tomreynyour /boot seems to be a directory on /dev/sda200:07
gmcastilit is00:07
gmcastil /dev/sda1 is mounted at /boot which is a directory on /dev/sda200:08
tomreynhuh? this makes no sense00:08
tomreynfindmnt should provides some clarity00:09
tomreyn*provide00:09
gmcastili think /etc/fstab was wrng when i booted and systemd in some way modified the file00:10
gmcastilsomething is really wrong..../dev/sda1 isnt mounted anywhere00:11
tomreyni believe that /dev/sda1 is not in use.00:11
gmcastili concur00:11
tomreyngrub will be on the MBR of this (or a different) disk.00:12
gmcastilthere's only the one disk with two partitions00:12
tomreynsda1 is a vfat file system created for uefi booting, it is meant to be an efi system partition.00:12
tomreynboth the root ("/") and /boot file systems are on the single ext4 file system that is on sda200:13
gmcastilwell, the root filesystem contains the boot directory, yes00:13
tomreyni.e. you do not ahave (or need, in this setup) a separate /boot file system (or partition)00:13
tomreyn*have00:14
gmcastilso it looks like i had uefi and then blew it away and then restored it as an mbr00:14
gmcastilwell, gpt that is00:14
morgan-u2testing00:15
tomreynat some point you used to have something set up sda1 for uefi booting. whether this system ever uefi booted though, i do not know.00:15
tomreynmorgan-u2: please use #tests00:15
gmcastilmaybe i should just leave it as is then00:16
morgan-u2oh chrome has frozen again. I am used to it just quittin but this is the old freeze comeing back. SMH. I was just testing if IRC worked. the text editor didnt.00:16
gmcastiland just neglect the 500MB primary partition00:16
morgan-u2tomreyn, sorry if I said it wrong.00:16
morgan-u2you remember mecomplaining. just quitting is much superior to freexing.00:16
tomreynmorgan-u2: i'm kindly asking you to do your tests on a channel where spurious channel activity makes no difference to anyone.00:18
tomreyn(in he future)00:18
EriC^^gmcastil: what does 'ls /sys/firmware/efi' give?00:18
tomreyngmcastil: you could wipefs sda1 and remove it (and the note on it) off fstab00:18
tomreynthat's if the above directory does not exist00:19
morgan-u2sure tom, no problem00:19
tomreynmorgan-u2: thank you.00:19
webchat33Hello, how do I remove snap completely off my system?00:20
tomreynwhich ubuntu release are you running? are you aware of the consequences? do you also want to prevent it from being re-installed later?00:21
xanguaShort answer is you don't00:21
xanguaOr maybe I'm wrong00:22
tomreynwell i tend to agree with you00:22
webchat33tomreyn: I am using Ubuntu 23.04, yes and yes00:22
tomreynso you don't need a web browser?00:23
webchat33I have installed one via flatpak00:23
tomreynhttps://www.baeldung.com/linux/snap-remove-disable and https://haydenjames.io/remove-snap-ubuntu-22-04-lts/ are two guides which i assume should both work. keep in mind that a standard 23.04 and later ubuntu install will expect that snap is available / can be installed, so you'll be in unsupportable terrain sooner or later.00:25
webchat33ok thanks00:26
tomreynalso note that removing snap's can cause data in ~/snap/ - such as browser profiles, to be deleted without prompting.00:26
Your_Doggot it00:26
Your_Dogooops wrong channel00:27
gmcastilEriC^^, no efi entry in sys/firmware00:29
tomreyngmcastil: starting with a slash, though, /sys/firmware/00:30
gmcastilyeah00:30
tomreynso you booted in bios mode, not uefi00:30
gmcastilapparently so00:30
tomreynand if you will continue to do so, you won't need the file system on sda1, the partition that is sda1, nor the reference to either in /etc/fstab00:31
gmcastilyeah i dont have EFI enabled in the VM - i've never done that either00:31
gmcastilso i'm unsure as to why that was ever done that way in the first place00:32
tomreynwe will not (need to) determine this reliably.00:33
gmcastilyeah its not necessary i dont think00:33

bobdobbsI'm trying to install a package using apt-get. When I do 'apt-get -y install cuda', I get "some packages could not be installed..." This is the full error:  https://hastebin.com/share/kefurukoki.ruby07:38
bobdobbsReading this error output, I guess that I have to install something called 'libnvidia-compute-535'. But when I do 'apt-get install libnvidia-compute-535', the prompt returns nearly immediately with a message saying that I already have the latest version installed07:39

paul424toddc, oki thanks07:40

ubottubobdobbs: Packages in Ubuntu may not be the latest. Ubuntu aims for stability, so "latest" may not be a good idea. Post-release updates are only considered if they are fixes for security vulnerabilities, high impact bug fixes, or unintrusive bug fixes with substantial benefit. See also !backports, !sru, and !ppa.07:41
bobdobbstoddc: I'm not sure what to do with that information07:44
toddccuda is from nvidia and may need files not avaible yet to ubuntu so you may need to locate then elseware or build them07:44
toddcbobdobbs: I am reading https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#ubuntu07:45
bobdobbstoddc: yeah, I'm still trying to figure out the cuda/nvida/ubuntu landscape as well07:46
bobdobbstoddc: I think I *might* have found a workaround: that package that is already installed? I purged it.07:47
bobdobbstoddc: then I ran 'apt install cuda' again, and it's running now07:47
toddcbobdobbs: good luck07:47
bobdobbstoddc: it's all a bit nerve-wracking, cos if something goes wrong then I might not get video after a reboot07:47
bobdobbstoddc: thanks07:48
bobdobbstoddc: k, cross your fingers for me. I'm gonna reboot...07:49
toddcI am lucky I do need latest and can stick to test stable (old)07:49
bobdobbstoddc: it worked! I have nvidia drivers working again!08:11
bobdobbstoddc: And I think I have the cuda toolkit installed property, cos I have stable diffusion running again. I think that that needs the cuda toolkit08:11

iomari891greetings, Is there any downside to adding a gui to my server?09:57
ComputerTechFrom what i heard, it's usually best to use the ubuntu desktop iso09:58
StucKmaniomari891: more attack surface, but it depends what exactly you want to do with it09:58
StucKmanmy home server has a desktop because it's also a media center, but it's behind 2 NATs09:59
akikiomari891: i use xpra to open a terminal from my server, then open other programs from that terminal09:59
StucKmanalso what akik mentions, you can install GUI tools w/o installing a whole desktop10:00
iomari891Some of my clients ae using suse server and some are using centos. Both have GUIs. FOr me it'snt an issue but some of my clients want a gui frontend to work with.10:00
StucKmanbut it's more 'unstable' because you need 100% connectivity, otherwise the program just finishes and I think it even crashes (in the sense that it doesn't try to do a graceful quit)10:01
iomari891These clients have physical access to their servers or local connections.10:02

BluesKajHi all11:47
jadesoturihi all. we have a ubuntu 20.04 vm running on vmware. it has to kernels installed: linux-5.4.0-65-lowlatency and linux-5.4.0-164-lowlatency.  at the moment i do not have access to the vmware console, and cannot use the grub meny to select which kernel we fish to boot, so it boots the older  -65 version.  ive tried changing the /etc/default/grub to GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 5.4.0-164-lowlatency" and running update-12:32
jadesoturigrub, but after reboot uname -r stil shows the older kernel.12:32
jadesoturii also tried purging the -164 version with apt, rebooting, installing it again and rebooting, with no success. it seems its stuck on the -65 version for some reason. why what how? about to go mad here :P12:33
ElliriaHey there. Can this command be changed to work on just the Firefox Snap or can it only be used for all Snaps? sudo snap set system refresh.retain=312:38
coconutAny reason for why snap is considered better than flatpak?12:41
tomreynElliria: it seems to be a system-wide setting. as you noticed, there is #snappy for snap specific questions, too.12:42
NickHNIH12:42
NickHSandboxing is more robust12:43
ElliriaYeah, they didn't answer last night and haven't answered today, so I thought I'd ask in here. Thanks.12:43
tomreyncoconut: there are many comparisons online, discussing pro's and con's. a relevant advantage of snap would be how it isolates snaps from the rest of the system. flatpaks do this to a much lesser degree.12:43
coconutoh ok, thanks tomreyn12:44

tomreynjadesoturi: check your /boot/grub.cfg -which files are referenced? check the /linux symbolic link, which kernel image does it point to? make sure you run update-grub after editing /etc/default/grub13:11
jadesoturitomreyn: boot.cfg looks correct. its referencing the correct images for all menu choices. but the /linux symlink - where is it located?13:14
jadesoturiand i have ran update-grub after making changes. also tried the grub-set-default. I see the default and grubenv files are updated with my changes, but after reboot, still returns -65 kernel in uname -r13:15
tomreynsorry, i meant /vmlinuz13:16
tomreyni guess your virtualization uses pvgrub/pygrub or similar to select the kernel to boot externally13:17
tomreyn(overriding any configurations you make on the system)13:17
jadesoturiyeah except for i have 10 other vms where i changed from -generic to -lowlatency with no problem.. one would think pvgrub would have the same effect there?13:17
tomreyni won't make assumptions on how reliable / reproducible your virtualization is13:18
jadesoturiits a pretty standard vmware esxi setup from what i know, but im in devops not on the infrastructure team so cant say for sure my self:P13:19
tomreynso it might be a good time to talk to the infrastructure team13:19
jadesoturivmlinuz is pointing to the correct image(boot/vmlinuz-5.4.0-164-lowlatency) and the vmlinuz.old is pointing to the -65 version13:20
jadesoturiyeah. already tried but the one guy there that knows anything about linux is unreacheable at the moment:P so trying other ways :)13:20
tomreyncat /proc/cmdline    says what?13:21
jadesoturi-65 .. but WTH?13:21
jadesoturiwhat sets the cmdline ?13:21
tomreynit certainly says more than that13:21
jadesoturi-65 as in its pointing to the old image :)13:22
jadesoturiBOOT_IMAGE=/vmlinuz-5.4.0-65-lowlatency root=/dev/mapper...13:22
jadesoturibut should that not be updated with update-grub or something?13:23
tomreynwell, you'll need to reconfigure esxi most likely. i'm not too familiar with how it boots.13:23
jadesoturiok. thank you, ill follow up with the infrastructure team in the morning i guess...13:25
tomreyni suspect you're using the VMware ESXi - Guest Bootloader - Direct Kernel Boot option there.13:25
jadesoturihmm that would be weird... especially since all these VMs are setup at the same time IIRC and no other VMs have this issue. but thank you for the pointer. ill see what they figure out tomorrow i guess13:26

ravageyou can install from one USB drive to another with the normal installer16:54
eelstrebori had to edit /etc/gdm3/custom.conf instead of /etc/gdm/custom.conf - got rid of the autologin but when i click on a user i get a black screen and it looks like it flashes every few seconds - i'll try nomodeset and edit /etc/gdm3/custom.conf to disable wayland and see if thinks work on a reboot16:55

Yakovhow to run pyton script with shortcut?20:46
VishI am currently running 22.04 on my machine. If I upgrade to 23.04 will I be able to upgrade to 24.04 next year?20:51
xanguaTo upgrade to 23.04 you first will have to 22.10. And to upgrade from 23.04 to 24.04 you'll have to upgrade to 23.10 first.20:53
Vishxangua so upgrading 24.04 will not be an issue right? I am new to Ubuntu and the versions and the things like interim and LTS is bot confusing when coming from Windows20:54
Eickmeyerxangua: That's false as 22.10 cannot be upgraded to, it's EOL.20:56
EickmeyerAnd you can upgrade LTS-to-LTS without using the regular releases.20:56
xanguaThat's up to you, you can upgrade thru all the releases if you want or just patiently wait for 24.04 and you will be able to upgrade from 22.04 to 24.04 directly20:56

tomreyn^ i'm responding in #ubuntu-de22:55
tomreynYakov: you should not change the device nodes' permission, but temporarily run code with elevated permissions (ideally much restricted / functtionally limited code, which maybe passes what it learnt to code running with less permissions)22:57
tomreynkind of what sudo or suid could do22:58
tomreynbut this is more of a #programming question really22:58

SlartibartI'm running Ubuntu 22.04 in virtualbox. But for some reason I can no longer log in. I get to the login screen, enter my password, it works for a long time(30 seconds-ish?), but then it returns to the login screen. Can I somehow run it in failsafe mode or something?22:59
grySlartibart, hello,23:24
grySlartibart, you could change to tty1 (ctrl+alt+f1;  note it is ctrl+alt+f5 or f6 or f7 to get back to your normal login screen). tty1 is a command line only. Once logged in, install some other login screen software different from what you currently have, and set it as default, then reboot. (I think "sudo apt install xdm" could do the job.)23:25
grySlartibart, if that works, at least you'll have a working login where to troubleshoot further.23:25
