Errors when updating

Problem Description

When I run sudo apt update through ssh, I get several warnings that updates could not be retrieved because the links could not be resolved (in German below). I discovered the issue after re-runnig the setup for Matrix (in Plinth) and getting an error message about the apt command failing. So I checked to see what happens when manually running apt update.

I re-ran the setup for Matrix because I appear to be having federation problems, despite Matrix Federation Tester saying everything is working. The error message I receive in Plinth for Matrix is:

Error updating app: Apt command failed with return code: 100 Details

My sources list via $ less /etc/apt/sources.list:

deb http://deb.debian.org/debian trixie main
deb-src http://deb.debian.org/debian trixie main

deb http://deb.debian.org/debian trixie-updates main
deb-src http://deb.debian.org/debian trixie-updates main

deb http://security.debian.org/debian-security/ trixie-security main
deb-src http://security.debian.org/debian-security/ trixie-security main

Do I need to change my sources list? Or something else to resolve these update issues?

I don’t use matrix and I don’t have much clue about it.

My general advice would be to:

  1. remember that the Pioneer is very slow (possibly hours) for upgrades
  2. wait for automatic ugprades (like, a few days)
  3. if that does not work, try manual upgrade from plinth (the web interface)
  4. only if that does not work and something is broken, use ssh and apt
  5. try aptitude instead of apt (same syntax usually works), sometimes it is better able to sort things out

On this case, what does apt-mark showhold say?
If python3-rpds-py is marked, you can try sudo apt-mark unhold python3-rpds-py and then sudo apt --fix-broken install. Then, you can try update and upgrade again.

For Matrix Synapse, we are waiting for this issue to be fixed:

Perhaps you can try installing python3-typing-extensions >=4.14.1 from unstable. Although, from reading the error logs, I’m not sure if this is the same issue.

Thank you for the tips @Avron and @jvalleroy.

I noticed that I have two sources lists in /etc/apt/:

  • sources.list
  • sources.list.fbx-dist-upgrade

(There are also the lists /etc/apt/sources.list.d/freedombox2.list and /etc/apt/sources.list.d/freedombox-unstable.list, but I have not touched those.)

The two lists were identical, so I commented out all repositories in sources.list.fbx-dist-upgrade. The same warnings persisted, so I also changed to a different mirror in sources.list (leaving http://security.debian.org/debian-security/ as it was). Again, the same warnings came up when running apt update via ssh.

However, after running an update in Plinth and rebooting, I again ssh’d into the FreedomBox and checked sudo apt update. The warning messages are now gone. So, commenting out the redundant repositories and/or changing mirrors and/or rebooting seemed to fix the problem.

Is it safe to delete sources.list.fbx-dist-upgrade?

The Matrix issue appears to be fixed after running sudo apt install -t unstable python3-rpds-py python3-typing-extensions via an SSH connection. Updating both packages from unstable was necessary. Thank you for the help, @jvalleroy!

I would appreciate feedback if deleting /etc/apt/sources.list.fbx-dist-upgrade is safe. I am hesitant to change or remove configuration files created by the FreedomBox scripts.

Thank you - that worked for me too.
