In returning from the swamp and the alligator wrestling I set out to try the new 2.10d. I am running it right now on a Raspi4 with 4 receivers 40,30,20 and 17 meters. The installation was straight forward on a new sd with the latest Buster. Just the basic system with the desktop. I did not have any problem ( I know the drill now) during set up and installation.
