No I don't run StellarMate, i have my own configured Rasbian with all needed software, including compiling sources.
Apart from the missing data in analyze-file (and som chrashes) it works OK.
I think I will test an Ubuntu also instead of wasting time on my homecocked solution!
I guess you run everything on the Raspberry PI, Kstars, Ekos and indilib? Do you access using a VNC-viewer or similar?
