Jellyfin not starting after update

[edelvall]

Thanks for that conor, but it didn't seem to help

Check the logs. In my case I noticed that the /var/lib/jellyfin directory requiered more space.
Then check the amount of free space using something like : df -sh
and increase the size of the partition. check your OS documentation for that.

This worked for me. I have a LXC container inside Proxmox running Jellyfin. It worked like a charm.
