SOLVED: Jellyfin service not starting

[umunas]

UPDATE:

Created fresh LXC in Proxmox and installed Jellyfin, configured CIFS and GPU passthrough and everything works for the time being even after several LXC reboots. I backed up LXC with working Jellyfin and will not touch it unless completely necessary. So, fingers crossed I won't have this problem. I have no clue what was the reason for it previously.

The strange thing about previous LXC was its size which was close to 14GiB with almost the same config as the new one, but the new one is only 1.83 GiB.

Go to /etc/jellyfin in the LXC and if migrations.xml is zero bytes, delete the file and restart Jellyfin.

o.k. that fixed the not starting issue for me after upgrading to 10.10.
It now starts, but soon dies - goes from      
Active: active (running) since Tue 2024-11-05 22:08:05 CET; 10s ago 
to 
Active: inactive (dead) since Tue 2024-11-05 22:09:23 CET; 34s ago

Why is this happening - how can it be fixed to get it up, keep it up and become reachable again?

Code:

root@jellyfin:/var/log/jellyfin# systemctl status jellyfin

could the kept back upgrade be the cause?

I'd need to see more of the log than just the tail end.

Did you install Jellyfin manually? Not sure how else the source would be "unknown". What is the output of this command?

Code:

sudo apt list --installed | grep jellyfin
