[ubuntu-studio-users] ubuntustudio-controls does not run

[Mac]

Interesting.  I have a UBS 19.04 install that,  after a recent apt update,
started giving huge numbers of "BUG: scheduling while atomic" errors at
boot and at shutdown. Runs fine though. And no errors with generic kernel,
or liquorix low latency. 🤔
