Gpredict is very easy to install on a Raspberry Pi. I did so on the "Buster" version of Raspbian. There is a .deb file to download and it just installs and runs. Disclaimer: I have not tried to use it more than just to see that it started up ok and displayed satellites. 73, Burns WB1FJ

When I first set up my groundstation, I was exclusively using Gpredict on a Pi 3B+ to run my G5400b rotator (along with hamlib rotctld). No problems whatsoever.
