Failed to update on Pop_OS 22.04 LTS

[nalakawula]

I tried apt update this morning and encounter following error:

Setting up incus-base (0.7-202403261636-ubuntu22.04) ...
Failed to restart incus.service: Unit incus.service not found.
dpkg: error processing package incus-base (--configure):

E: Sub-process /usr/bin/dpkg returned an error code (1)

It was solved by removing incus and incus-base then reinstall them.

I am using stable repo

/etc/apt/sources.list.d/zabbly-incus-stable.sources
Enabled: yes
Types: deb
URIs: https://pkgs.zabbly.com/incus/stable
Suites: jammy
Components: main
Architectures: amd64
Signed-By: /etc/apt/keyrings/zabbly.asc

Thank you

Would have been interesting to get some of the systemd state before removing and reinstalling the packages as there's now no way to figure out what caused the issue :(

[stgraber]

Closing as there's no further action we can take once the packages have been removed and reinstalled.

It's almost certainly an issue with a local override (manual or automatic) of one of the units in /etc which didn't get automatically cleaned on upgrade, but we'll need someone else to hit the same situation to be able to figure it out.

@stgraber I just hit the same issue on Debian 12 using the stable repo. I have not reinstalled yet in case you want me to help troubleshoot.

3 packages can be upgraded. Run 'apt list --upgradable' to see them.

Now when I run systemctl status incus I get this output.

[stgraber]

Can you show ls -lh /etc/systemd/system/incus* ?

[broizter]

❯ ls -lh /etc/systemd/system/incus*
lrwxrwxrwx 1 root root 43 Dec  3 10:11 /etc/systemd/system/incus.service -> /opt/incus/lib/systemd/system/incus.service

[stgraber]

Okay, thanks. Can you delete that file and then try the update again?

[broizter]

Just to make sure, the one in /etc or the one in /opt?

[stgraber]

/etc/systemd/system/incus.service

[broizter]

Success!

Pushed the fix for it, I'll release the package to stable once it's built.

It's odd because incus.service and incus-user.service are socket-activated so they should never have had their units symlinked into /etc/systemd/system to begin with, it's also not a thing that I've noticed on any of my test systems. Anyway, the updated logic will take care of it.

[broizter]

Great!

If I remember correctly I have not done any overrides of the Incus systemd services and I've used this repository from the very beginning.

Anyways, I've been a long time user of LXD and now Incus so I'm happy I could be of any help, however small it was. Keep up the great work!
