On PI4 I have installed Astroberry last year and I have upgraded/updated the environment systematically, but the ASTAP version is always the old one( Version ß0.9.300 dated 2019-11-17). How can I update this software safely?
one can see that it‘s not in any repository. So you‘ll have to download the package yourself and upgrade manually. I created an issue for Astroberry so one‘s able to fing this info.
