Can this be fixed,
Thank you in advance.

When pasting terminal output, highlight it and use the Preformatted text </> button.

Alternatively, add three backticks ` above and below the text:

Please edit your post accordingly.

The problem is with the libgnomecups Gentoo patches that no longer exist:

I would notify the AUR package maintainer by leaving a comment letting him know there are new patches to follow the Gentoo package.

Thank you very much, I already had a suspicion that it would be something like that.
I am new here and only 2 weeks in Manjaro, before I did not know what “AUR” was.
But I’ll find out who to contact. Thank you for the assistance.
