Server operating system version

Debian 10.13

Plesk version and microupdate number

v18.0.60_build1800240329.08

Hi guys,

this is my first post here and I hope i'm at the right place. I recently found out, that my update manager in Plesk Obsidian v18.0.60 on Debian 10.13 throws an error and does not show any updates.
Error-message:
Paketliste konnte nicht abgerufen werden: Traceback (most recent call last): File "/opt/psa/admin/sbin/pum_worker/.bootstrap/_pex/pex.py", line 332, in execute File "/opt/psa/admin/sbin/pum_worker/.bootstrap/_pex/pex.py", line 262, in _wrap_coverage File "/opt/psa/admin/sbin/pum_worker/.bootstrap/_pex/pex.py", line 294, in _wrap_profiling File "/opt/psa/admin/sbin/pum_worker/.bootstrap/_pex/pex.py", line 375, in _execute File "/opt/psa/admin/sbin/pum_worker/.bootstrap/_pex/pex.py", line 433, in execute_entry File "/opt/psa/admin/sbin/pum_worker/.bootstrap/_pex/pex.py", line 438, in execute_module File "", line 229, in run_module File "", line 88, in _run_code File "/opt/psa/admin/sbin/pum_worker/papt.py", line 6, in File "/opt/psa/admin/sbin/pum_worker/apt_wrapper.py", line 11, in ModuleNotFoundError: No module named 'apt_pkg'

The system update list below is empty and can't be refreshed.

I don't know how or when this happened. In addition my knowledge is basic in this whole plesk thing, I know enough to manage my domains..

Appreciating any help or recommendations what to do.
If you need any further informations, just tell me.

Thank you very much in advance

This post on askubuntu.com discribes an similar issue. The suggestion there is to reinstall apt_pkg using:

sudo apt-get install --reinstall python3-apt

EDIT: for anyone else reading this, don't use this command. It will probably break your Plesk installation. See post below.

Hi @Kaspar

I already tried this one and destroyed my whole plesk installation because it uninstalled all the other packages regarding plesk too and didnt install it afterwards. I had to activate the backup from my plesk server.

Sorry to read that it broke your Plesk installation. You could try to run a Plesk repair with the command plesk repair installation. But I am not completely sure if that will fix the issue you are having. It will at least not break your system again.

If that does not work either, the best suggestion I have left is to create a ticket with Plesk support.

Thank you for your fast reply. I tried this one, but it didnt help. Log-file does not say anything wrong and there is no repair_problem.log.

On monday I will create a support Ticket.
Thank you for your time and help!
