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 attempts to copy binaries onto a system on a manner that avoids the single source of truth used for regular installables. So it invites dependency hell.
Is this the one that seems to need a binary running constantly in the vast in-between times when no installation is taking place? That would be a risk.
Never used it. I worked in OS security and don’t need that stress either at work or home.
