Wouldn't the moral of the story be "don't use Fedora Flatpack"? Tbh, the moral I drew from the story was "Don't use Fedora".

It works if you use OBSs own flatpak. It's just Fedora which modified it, broke it, and shipped it broken.

initially used redhat then fedora till 2006

switched to ubuntu for desktop and debian for server in 2006 for my company, by 2020 most developers chose mac for desktop and debian/ubuntu for server
