[11.0] Jellyfin doesn't start up

[sobosobo]

Hi all!

I have a Jellyfin setup on the MacOs AMD64, from .dmg file. I had long-running instance, that I updated to 10.10.7, made backup of jellyfin directory in Application Support, and installed 10.11.2. I received multiple errors in logs and there was no movement after a few hours, so I stopped jellyfin, restored a directory from the backup, installed 10.10.7 back and disabled/deleted all custom plugins that I had (it seems that they could resolve in issues).

My instance of 10.10.7 is running smoothly on this configuration, however, if I repeat the process (stop 10.10.7, install 10.11.2, run 10.11.2) I got absolutely no activity. Icon of Jellyfin is in tray, but no logs, no CPU activity and no webserser running. I tried to enable debug logging, but still nothing in the logs. Do you have any ideas how to troubleshoot the startup issue?

Figured it out! Default manual of backup restoration asks you to do sudo cp -a ... which in turn makes jellyfin folder ownership to root user. It seems like 10.10 version is tolerant to this ownership mismatch, and a new one is not. sudo chown -R myuser ~/Library/Application\ Support\jellyfin helped
