I have confirmed that citydb.sqlite is in the usr/share/kstars directory. I haven't done a lot of research on this yet, but I wanted to know if anyone else has run into this problem and has an idea what is going sideways. My initial thought is that it could be a missing environment variable or something like that. Please let me know if you have any ideas.
That is interesting. It was a fresh install of kstars in Armbian and it did not have that package installed. It didn't give me any warnings that there were missing or broken dependencies when I installed it.
