Public bug reported:
Hi, my Dell XPS 7390 worked just fine with Ubuntu 19.10, but after
clean-install upgrading to 20.04 I don't have working bluetooth any
more. The machine has an Intel AX200 installed. I'm not sure what
details are helpful to provide, so here are some random things, happy to
provide more if people can provide hints...
