Ok, here goes.
I installed clamav, verified it worked, then set up a cron job. When I did an update to nextcloud it failed; and I ended up re-installing and copying the files back into the new installation. Then I noticed that other apps were behaving weirdly! I had gone through most of my apps this morning and they were all working; now I had various problems. Dropping into the shell and doing a look-see I immediately spotted something strange. Most of my app related directories had ownerships that do not seem correct. The group owner appeared especially suspicious with an owner of systemd-timesync. And I don’t remember an owner of _apt being correct. For example the newly installed nextcloud had ROOT as owner and group.
Looking at the directory where I have most of my app data:
admin@tatooine[/mnt/Main/app_storage]$ ls -l

And the pgvecto container of immich (which is cycling between deploying and stopped) has permissions issues:

I know some of my apps had admin as owner and group but I don’t know for sure which ones. My IDrive does not seem to show the ownership information.
Before doing something (more) stupid I wanted to run this by the experts ;-).
Thanks,
jengle
I hear you chuckling…
