E: The list of sources could not be read.
This thing pops up when i try to install, update or do anything with apt. I tried removing the key and reinstaling it. Like in this post https://jellyfin.org/posts/jellyfin-apt-key/. But with no success. Any ideas?
I deleted every source-list and jellyfin keys using
sudo rm /etc/apt/sources.list.d/extrepo_jellyfin.sources
