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?
Flatpaks saved my bacon when I borked my Linux work computer and didn’t have time to fix it. Spent 2 months with half my apps on Flatpak because the native ones weren’t working.
It’s also great as a developer. While I do provide x86 and arm binaries, I don’t bother distributing them in 20 different formats. The website links to Flathub, and the number of distro/Mesa specific issues has dropped to 0.
