Depends on how your distro manages flatpaks. The command line "flatpak install ..." method is certainly available but at least on Fedora it also integrates with the Software app IF the flatpak is in a repo.

Currently I'm only providing a standalone file. Additionally I have the chirp version in the filename which is both a good and bad thing.

I'ts good because you know what version you're installed, it's bad because you could potentially install multiple versions since they have different names. I haven't tested this yet.

Short term you can remove the old version before installing the new version. Medium term I can look at getting it into a public Flatpak repo.

Long term the solution HAS to be to get chirp running on Python 3 / Gtk 3.

Thanks,
