The issue with Golf build from AUR page (see https://golf-lang.blogspot.com/2025/02/golfs-package-page-on-aur-for-arch-linux.html) has been fixed.
File 'arch.install' was recently added, but wasn't a part of AUR git repo for Golf. This has now been fixed, and you should be able to install Golf from its AUR page (see above link).
Also, the Debian/Ubuntu package creation (see https://golf-lang.blogspot.com/2025/02/create-deb-installation-package-for-golf.html) has been re-tested and updated, since Golf has changed to a non-native package (most packages are).
