SOLVED: Unbuntu Software updater crashing

[TheDreadPirate]

Ok. What is the output of "sudo apt list --installed | grep jellyfin"? I'm assuming Jellyfin is there.

What version of Ubuntu are you on? 24.04? 22.04? I'm guessing 24.04 based on what you said in the opening post. If so, you can try upgrading jellyfin-ffmpeg since jellyfin-ffmpeg5 has not, and will not, be rebuilt for Noble.

Code:

sudo apt install jellyfin-ffmpeg6

That should replace jellyfin-ffmpeg5 with 6, which has been rebuilt for 24.04 Noble and should satisfy apt.
