maybe the comments in this post help? https://lemmy.ml/post/40864672 and/or consider posting in one of the jellyfin communities like /c/jellyfin@lemmy.ml or /c/jellyfin@lemmy.world ?
My guess is you probably need to go into terminal and probably fix the folder/file permissions for your media library folders (using chmod), then remove/re-add that media library in jellyfin itself so it can scan the folder properly. But that’s just a guess without really knowing your actual set up.
PS - Don’t worry about Ubuntu, once you get your initial setup figured out everything will run stable.
