I'm using KStars 3.4.3 on R Pi 4 (installed with @rlancaste's AstroPi3 scripts).

Trying to switch to nightly builds, but get the error below.

Apparently nightly isn't available for Raspbian/buster?

Shall I try a different distro?Any advice would be appreciated.

You could install from the source and compile on your Rasbian OS, or you could install Ubuntu MATE 20.04 and use the regular update channels.
Ubuntu MATE 20.04 works great for me. Stable and no issues to speak of.

Thank you! Will experiment with a test machine.

Do you run 64 or 32 bit MATE 20.04? Which do you recommend?

Also, do you recommend installing a beta of MATE 20.04 from ubuntu-mate.org or installing the ubuntu 20.04 server and then separate.y adding the MATE desktop?

Or maybe it doesn't matter?

I installed as I described here: indilib.org/forum/general/6922-kstars-on...4.html?start=0#53293

I am running 64 bit, did not try 32 bit, but I ran that with Ubuntu 19.04 and that worked fine as well.
So, can't give a recommendation, really, only to say that the 64 bit version works just fine for me.

PS: Forgot to mention: I am running this on an RPi4 with 4GB RAM from the SD card with an SSD to save images to attached. Have not yet converted to booting from the SSD, as the system runs flawlessly and pretty fast from the SD card.
