I have installed net-firewall/ferm on my Raspberry Pi 5 with aarch64 (arm64) and it works like a charm. Please add the ~arm64 keyword to version 2.7 (the tested version). It's a Perl script, so there is little risk for future breakage, as long as Perl remains operational ;-)
Unable to check for sanity: > no match for package: foo/bar
Please populate the package list properly.
Apologies, I used the new template but forgot to set the right package. Can you still process this request or do I have to create a new one?
All sanity-check issues have been resolved
arm64 done all arches done
