I don't like flatpak: if there is a shared library bug, it can be fixed once on a normal Linux distro. With flatpaks, each one that uses the library must be update. But will they? Furthermore, there is a lot less sharing of disk space and RAM. $ flatpak list --columns=name [1mName[22m Element Bluefish Fedora KDE 6 Platform Fedora Platform default fedoraproject platform translations Freedesktop Platform Freedesktop Platform Mesa Mesa (Extra) Mesa Mesa Mesa (Extra) Mesa (Extra) FFmpeg extension with extra codecs openh264 openh264 openh264 GNU Image Manipulation Program Déjà Dup Backups GNOME Application Platform version 46 KolourPaint Paint Telegram Telegram Desktop Webview Add-on I don't know why there are so many versions of a particular package installed. For example, here's more info about Mesa (ignoring Mesa (Extra)): Mesa …esktop.Platform.GL.default 25.0.3 23.08 flathub system Mesa …esktop.Platform.GL.default 25.0.3 24.08 flathub system Mesa …esktop.Platform.GL.default 25.0.3 24.08 flathub user There are two "branches"s: 23.08 and 24.08 and yet the versions are all 25.0.3. And why would one have "installation" "user" and the other two "system"?
