I'm on a Raspberry Pi 4 Cannakit build. I have had some troubles with a lot of various packages. I'm not sure if there's a way around this. I thought I read somewhere you have to use curl for everything, but I had trouble with that too. I'll keep playing around with it and see what I can find.

Ubuntu Studio packages aren't supported for Raspberry Pi. You're trying to do an impossible situation.
