Hello, good afternoon,
On Saturday the hypervisor was updated and since then a container based on Debian does not start. It is rare that there is another machine with Debian on the same host that boots. The error is as follows:

TASK ERROR: command 'systemctl start pve-container@100' failed: exit code 1

Can somebody help me? The hypervisor is up to date and I use the PVE repositories pve-no-subscription repository.

Thanks!

if you get that superblock error the image (and maybe the underlaying hw disk) is corrupted, have to ask coworkers what to do then.
