I have also installed and found that flrig and FLDigi did not install. I built from source and installed fine. guessing the BAP script is not installing the correct dependencies. I failed to write down the ones I installed, Sorry. I might try again soon. Also Pat does not install. And since you can't install from source guessing its because there is no arm64 version deb file.
everything else seem to work from what I have seen. will continue to play
