SOLVED: Jellyfin attempting to access /jellyfin after server reboot

[TheDreadPirate]

Did you do anything that may have affected the jellyfin service? There are a lot of things missing in "show jellyfin". No environment file is set, which would include all the data paths and working directories for Jellyfin, the execstart doesn't include any options.

Let's backup your install data and reset Jellyfin.

Code:

sudo mkdir /jellyBackup
cd /jellyBackup
sudo rsync -a -p --progress /var/lib/jellyfin libJellyfin/
sudo rsync -a -p --progress /etc/jellyfin etcJellyfin/
sudo rsync -a -p --progress /var/cache/jellyfin cacheJellyfin/
sudo apt purge jellyfin*
curl https://repo.jellyfin.org/install-debuntu.sh | sudo bash
sudo systemctl stop jellyfin
sudo rsync -a -p --progress libJellyfin/jellyfin /var/lib/ --delete
sudo rsync -a -p --progress etcJellyfin/jellyfin /etc/ --delete
sudo rsync -a -p --progress cacheJellyfin/jellyfin /var/cache/ --delete
sudo chown -R jellyfin: /etc/jellyfin /var/lib/jellyfin /var/cache/jellyfin
sudo systemctl start jellyfin
