I tried to install isobar on Ubuntu 20.04, but got this:

If jack is the JACK Audio Connection Kit, is jack so necessary today for audio?

I've just reproduced this on Ubuntu 20 and see exactly what you mean. I guess this is now a requirement for the RtMidi library, although I don't know exactly what's changed here - I know that jack does also provide MIDI I/O so it must be something connected to that.

Fix is to install libjack-dev:

apt install libjack-dev

I'll add this to the Linux requirements documentation. Thanks! Let me know if you have any further issues.
