Upgrade fails with 'Failed to find executable apt-get'


I am trying to update a Ubuntu 22 VM but it fails with the following message in the event history:

In the shell I can update single packages with apt-get install --only-upgrade without a problem. A refresh of the software sources works also from suse manager. I also restarted venv-salt-minion but it does not help.

I would be glad for any suggestions.

With kind regards,
