| copec | I'm working with dnsdist on Ubuntu 22.04.2, and looking at this for eBPF https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/BHI | 00:01 |
|---|---|---|
| copec | It seems though that when kernel.unprivileged_bpf_disabled=2 that even giving bpf capability with apparmor and in the systemd unit will allow eBPF to work, but when kernel.unprivileged_bpf_disabled=0, then anything unpriviledged whether restricted by apparmor or not can use eBPF. Is this normal behaviour? How can I still just restrict it to the dnsdist unit? | 00:01 |
| copec | Sorry, I meant when kernel.unprivileged_bpf_disabled=2 then nothing allows ebpf to work, but when kernel.unprivileged_bpf_disabled=0 then it works for everything no matter whether it has the capability or not | 00:03 |
| Liowenex | mitigations=off | 00:04 |
| sarnold | I wonder if mitigations=off works for that. I'd be surprised. | 00:06 |
| Liowenex | At the very least they'll notice an increase in CPU performance | 00:07 |

| dabbler | I can't figure out why I have significant space remaining unusable on my /boot btrfs. There's only one subvolume (other than id 5) and there's nothing outside it. I just booted so there shouldn't be any unlinked files open. Yet 2/5ths of the filesystem isn't available. Any ideas? | 05:39 |
| webchat24 | 23.04 proposed... after an update of the shell i dont get the normal login screen but only terminal... how do i get into the desktop and how to get the login screen back at boot? | 05:44 |
| dabbler | webchat24: sudo systemctl start [*].service | 05:47 |
| dabbler | Where [*] depends on your flavor of Ubuntu | 05:48 |
| webchat24 | ubuntu 23.04 proposed | 05:48 |
| dabbler | Ok, for "plain" Ubuntu, it's gdm or gdm3. I forget which but it should autocomplete with tab | 05:49 |
| webchat24 | unit service.service not found | 05:50 |
| webchat24 | gdm3 without service dosnt start desktop | 05:52 |
| dabbler | What about just gdm? | 05:52 |
| webchat24 | unit gdm.service not found | 05:53 |
| dabbler | Hmm press tab after the space after "start" to see all services | 05:53 |
| dabbler | Usually there are a lot | 05:54 |
| webchat24 | no gdm | 05:55 |
| dabbler | Does it list a lot? | 05:55 |
| webchat24 | 247 items | 05:55 |
| dabbler | Ok. Let me check what package provides it | 05:56 |
| webchat24 | dabbler thx a lot :) | 05:57 |
| dabbler | It's gdm3 haha | 05:57 |
| dabbler | What happens if you do "sudo apt install gdm3"? | 05:57 |
| dabbler | I'm guessing something went wrong with its installation during the upgrade to lunar | 05:58 |
| webchat24 | it installs gnome shell and so on | 05:58 |
| dabbler | It didn't say they're already installed? | 05:59 |
| webchat24 | and im back in the dektop... hurray :D | 05:59 |
| dabbler | Nice! | 05:59 |
| webchat24 | no... seems the latest update something was missing... some mutter updates were hold back | 06:00 |
| dabbler | How did you do the upgrade to 23.04? Through the "software something" UI in the desktop? | 06:01 |
| dabbler | Or with apt dist-upgrade? | 06:01 |
| webchat24 | with sudo apt full-upgrade | 06:01 |
| dabbler | Oh ok. I'm not familiar with that one. Were you following a guide? | 06:02 |
| webchat24 | i did in past with dist-upgrade | 06:02 |
| webchat24 | saw with help its full-upgrade | 06:02 |
| webchat24 | they should be the same | 06:03 |
| dabbler | Ok. I wonder if there's a log file you can check to see whether anything else failed to install properly | 06:03 |
| dabbler | webchat24: Is there a /var/log/full-upgrade on your system? | 06:06 |
| dabbler | Or a /var/log/dist-upgrade? | 06:06 |
| dabbler | Actually, it's probably simpler to just make sure every dependency of ubuntu-desktop got installed | 06:08 |
| dabbler | Do 'sudo apt install ubuntu-desktop' | 06:08 |
| webchat24 | no but dist-upgrade | 06:08 |
| dabbler | Ok, the contents of that directory are what should be studied if you end up needing to know what went wrong | 06:09 |
| dabbler | But you may not need to worry about that as long as you can get the ubuntu-desktop package (and all its dependencies) installed at this point | 06:11 |
| webchat24 | 12 things get installed with install ubuntu-desktop | 06:11 |
| dabbler | Ok, assuming they install successfully, I think you're good to go | 06:12 |
| webchat24 | thx a lot :) | 06:12 |
| dabbler | You're welcome | 06:13 |
| hid3 | Greetings everyone. I've got a small farm of Ubuntu 22.04 LTS servers which all run as VMs in one physical machine. They have some cron jobs in cron.daily, weekly and monthly schedules. The problem is that by default all the crons start at the same time, causing load/slowness on the main physical machine. Is there any tool which would somehow randomise the start times of cron.daily, cron.weekly and cron.monthly jobs? | 06:25 |
| dabbler | hid3: it would probably be cleaner to insert a wait into the "cronned" scripts themselves | 06:27 |
| dabbler | A wait period that's either hard-coded but different or random within a certain interval | 06:28 |
| hid3 | yeah, but that would mess everything up. E.g. if I insert into a script "sleep 6h" line on one server, and during that window the server reboots, the job wouldn't be executed. Starting it in time would prevent that | 06:28 |
| hid3 | It's hard to imagine that I'm the only one facing such problem | 06:29 |
| dabbler | Ah, I didn't realize the wait would be so long. Good point. You could get around that, but you're right that there might be an existing tool | 06:30 |
| ducasse | hid3: have you looked a systemd timer units? pretty sure they have a facility for that | 07:55 |

| chilversc | In launchpad, is there anywhere that details how a package was built? In particular what options were passed to ./configure? The package I'm mainly interested in is nfs-utils https://launchpad.net/ubuntu/+source/nfs-utils | 10:58 |

| BluesKaj | Hi all | 13:56 |
| oac_ | Hey there, I have a bit of a package reinstallation problem I'm hoping someone here might be able to help with. | 14:01 |
| BluesKaj | oac_,which package? | 14:02 |
| oac_ | So I installed a PPA which provided specialized versions of apparmor and the kernel. I want to remove those PPAs and reinstall the versions from lunar/main | 14:02 |
| oac_ | The packages are apparmor, dh-apparmor, libapparmor-dev, and libapparmor1 | 14:02 |
| oac_ | I removed apparmor, dh-apparmor, and libapparmor-dev, great. | 14:03 |
| oac_ | But I can't remove libapparmor1 because it is required by systemd-sysv | 14:03 |
| oac_ | and I can't reinstall the others because the version doesn't match | 14:03 |
| BluesKaj | remove the ppa and purge the related packages then do a normal package install, | 14:04 |
| oac_ | I've tried uninstalling with the --allow-remove-essential --allow-change-held-packages and it won't let me uninstall libapparmor1 | 14:04 |
| lotuspsychje | oac_: yeah, the volunteers cant advice on external ppa's | 14:04 |
| oac_ | Technically, it's an internap ppa ;) | 14:05 |
| lotuspsychje | !ppapurge | oac_ | 14:05 |
| ubottu | oac_: To disable a PPA from your sources and revert your packages back to default Ubuntu packages, install ppa-purge and use the command: « sudo ppa-purge ppa:<repository-name>/<subdirectory> » – For more information, see http://www.webupd8.org/2009/12/remove-ppa-repositories-via-command.html | 14:05 |
| leftyfb | oac_: sudo apt install --reinstall apparmor=3.0.8-1ubuntu2 libapparmor-dev=3.0.8-1ubuntu2 libapparmor1=3.0.8-1ubuntu2 && sudo apt remove --purge dh-apparmor | 14:08 |
| oac_ | leftyfb: that worked, thanks so much! | 14:12 |
| oac | lotuspsychje: thanks for the ppa-purge suggestion too, TIL, I assume it will help me out of some other mess I make sometime in the future | 14:24 |
| lotuspsychje | cookie here goes to leftyfb :p | 14:24 |
| lotuspsychje | oac: just of curiosity, what was your purpose to go replace default apparmor and kernel with ppa versions? | 14:25 |
| oac | I'm on the snapd team, working on a new apparmor feature that (used to) require particular kernel and apparmor patches. With the new kernel 6.2.0-23.23, those features are included, and snapd vendors apparmor now, so I just wanted to get all the non-standard things off my machine | 14:28 |

| ubottu | maya329: There are many ways to back your system up.

| maya329 | ok thanks! | 16:03 |
| tomreyn | i'd say borg backup, restic, rsync, bacula are the best tools, but which one to pick will depend on what you needs are. | 16:03 |
| tomreyn | rsync is not a backup tool by default, but can be one in the right setup | 16:04 |

| sarnold | apt-cdrom was written ages ago, when internet access wasn't as common | 23:38 |
| sarnold | and no one has updated it to support read-write media like usb sticks; apt-offline can do that, but that isn't integrated into the update guis, etc | 23:38 |

| sarnold | you're the third person I've seen ask for it in the last ten years; I suspect it's just not common enough to implement | 23:40 |
| wfburton | Can I go 22.04.2 LTS to 23.04 as an upgrade and not a reinstall | 23:41 |
| sarnold | yes, that should work fine | 23:42 |
| mybalzitch | be aware you can't go back to the LTS release though | 23:43 |
| wfburton | k I'll give it .. yeah I know | 23:43 |
| mybalzitch | you'd have to wait for the next LTS release and upgrade to that | 23:43 |
| mybalzitch | kk cool | 23:43 |
| wfburton | so I have to wait for LTS to come out | 23:43 |
| mybalzitch | if you want to go back to a LTS release | 23:44 |
| mybalzitch | like 22.04 (LTS) -> 23.04 -> 24.04 (LTS) | 23:45 |
| wfburton | k I'm having so issues with 22.04.2 LTS. GCC won't update and also I have unmet dependencies but doesn't said which ones.. | 23:46 |
| wfburton | ok thanks for the info... have a good night | 23:47 |
