what command line options are you needing for audio? i use kubuntu, and the only reason i hit the CLI is to provide a special output so i can implement multiroom audio, with Snapcast.
Otherwise, i think i could install most stuff without it. OO, maybe spotify needed to add an apt repo, however i think there maybe a seperate installer (snap?) which would negate that.
i feel like you were not going for a vanilla instance if the latest kubuntu/ubuntu needed work.
Perfect timing! My instance is shutting down, so I need to sync up my subscriptions!
Cheers
