SOLVED: Jellyfin upgrade issue

[guunter]

Hi folks,
I keep running into this issue every time jellyfin does a new release.
My jellyfin is setup as a lxc using proxmox helper scripts.

Code:

root@jellyfin:~# sudo apt upgrade jellyfin

E: Sub-process /usr/bin/dpkg returned an error code (1)

I've been solving it so far by backing up my config directory, deleting it and then restoring the files after the upgrade.
Is there a better way to do the upgrades ?

When you use the helper-script you're supposed to just type update in console. You don't need to do sudo apt-get upgrade
