Completely reinstalling jellyfin

[martyc1981]

so, I have completely screwed up my jellyfin install trying to alter system files with a wordprocessing app. Which saved a bunch of non-unicode date into the file. Causing the server to not start up. So I tried to reinstall all the files, but that just left me with a load of other issues. Then I tried to delete the /usr/share/Jellyfin directory and reinstall the whole thing. But that just caused more problems.

What I need is a complete deletion of Jellyfin from my system so I can just get it running and start again. I've tried sudo apt purge jellyfin, sudo apt remove jellyfin but nothing works, when I try to reinstall through the command line, I keep getting the error message saying "Jellyfin is already installed". How can I completely purge jellyfin from my system?

Code:

sudo apt purge jellyfin*
sudo rm -rf /var/lib/jellyfin /var/log/jellyfin /var/cache/jellyfin /etc/jellyfin /usr/share/jellyfin
curl https://repo.jellyfin.org/install-debuntu.sh | sudo bash

The asterisk in the apt command is important. It makes sure that it installs jellyfin-server jellyfin-web jellyfin-ffmpeg and the meta package "jellyfin".
