With the Steam Frame and Steam Machine launching with SteamOS Linux this year, we’re going to again see a nice boost for Flatpaks and desktop Linux overall.
Linux has, historically, been quite messy when it comes to software distribution. We have various distribution-specific packaging formats like .deb (Debian / Ubuntu), .rpm (Fedora) and the list just goes on and on. Canonical also went their own way with Ubuntu for the likes of Snap, but the real winner is going to end up being Flatpak and the main Flathub store.
I agree. I wish Flatpak used a proper package manager. You install one Flatpak and you need the entire freedesktop sdk even if you use a fifth of it. Install a second Flatpak and maybe do it again.
