I’ve been involved with Linux for a long time, and Flatpak almost seems too good to be true:
Just install any app on any distro, isolated from the base system and with granular rights management. I’ve just set up my first flatpak-centric system and didn’t notice any issues with it at all, apart from a 1-second waiting time before an app is launched.
What’s your long-term experience?
Notice any annoying bugs or instabilities? Do apps crash a lot? Disappear from Flathub or are unmaintained? Do you often have issues with apps that don’t integrate well with your native system? Are important apps missing?
It’s been great. I can get updated stuff on top of stable point release distro without mixing repos. Offers nice features like sandbox and forcing everything under .var for easy transfer to another machine.
There’s some small issues. For some apps fonts look weird but it’s fixable. Firefox is so sandboxed that KeepAssXC and KDE Connect/plasme browser integration has harder time with it. Managed to fix XC. Sometimes there’s issues with permissions. Well most those things were issues with permissions as in with the sandbox. But I think those issues will be settled at some point.
