Description
So, the website says that arch has smuxi in repo, but that is no longer true, if ever (I don't know). Assuming it was true, it was pushed out of community and into AUR, which is community maintained. Unfortunately, those builds haven't been updated in 2 years, and the build no longer works due to signing issues with log4net. If possible it might be good to adopt those AUR PKGBUILDs update them, and maintain them. I've looked at updating log4net, but I have no idea how to deal with either the binary, or the source archive. It seems to have changed its structure quite a bit in 2 years.
Alternatively, perhaps it's possible for smuxi to be packaged in snapd or flatpak. I'm not entirely certain how well gnome integration works if you do that, though. I think it should.
