Task result "Unknown" for daily task "Update package database"

[alietz]

Hi,

my newly installed PBS 8.3.3 shows the result "Unknown" for the daily Update package database task. There is not output in the task output window, and the status is:



When I update the package database in the GUI, everything works just fine. The syslog for the daily update looks good, too:

It's not a big issue, but I have set up a Nagios check for task errors, and so that came up.

Cheers, Andreas

Hi,
thanks for the report. This is a known issue, a patch has already been send to the mailing list to fix this, but still lacks some dependencies before being able to roll out, see also https://forum.proxmox.com/threads/task-daily-apt-update-status-unknown.162414/

Hi Chris, thanks for the fast reply. I'm looking forward to the patch and will exclude "unknown" from my Nagios tests in the meantime.

Keep up the good work on PBS!

Hey @alietz, I’ve run into something similar before—when a scheduled task shows “unknown,” it’s usually because something blocked it from starting or finishing properly. It could be as simple as the system not having internet access, or DNS settings being off. I'd suggest checking your /etc/resolv.conf to make sure DNS is set correctly, and maybe try running apt update manually in the terminal to see if anything pops up. That often gives a clearer idea of what’s going wrong. If everything looks fine there, have a look at the logs with journalctl—they can be super helpful. Hope it’s something simple and easy to fix! Let us know how it goes.
