I’m sorry, I found your response confusing. Arch is a Linux distro, I know flatpak is available for it. If there’s a bug with flatpak, I would expect it to be pretty much the same across most GNU based Linux systems. My question, however, was why use flatpak on Arch Linux at all, as the AUR has pretty much everything including the kitchen sink… unless you are developing flatpaks, I guess, in which then it would make sense to me.
You don’t owe me an explanation, it just sounded odd to me to be needing flatpak when there was AUR, was all.
