Hi Marcel,

This post may contain the info you need although I think that Astroberry is more of a problem to update.

My system is KStars on Ubuntu Mate 20.10.
I am unfamiliar with Astroberry so can't help there. A quick look through the above post suggests it should be helpful.

Jerry Black (thanks Jerry!) has developed a script that automates setting up KStars and would be worth a look. Here is the link.

Cheers,
