It gives me many more errors than what appears in the image
Someone suggested endeavouros to me since I needed a unix system to use sextractor for astronomical purposes and it didn’t have windows support
I have no experience with anything like this and I really need it to use sextractor and get the information from the fits files. any advice is greatly appreciated!!!
Looks like it was “ages” ago you updated your system.
For the issue depicted in your first screenshot:
Those packages were once part of the repositories. They are not anymore. Since they are not in AUR either, the package manager is solely informing you about them.
You could check with pactree -r X (replace X with the name of the package) to make sure nothing in your system is dependent on it. If that is the case, you could remove them.
