There is a lot of conflicting information in this thread. Installation of Steam from package manager VS deb from Valve VS official Flatpak VS official Snap. I know that the official Snap is terrible so I’m ignoring it. The Flatpak has some permission issue but I heard it solves some compatibility issues for some games.
Someone should make a comprehensive guide for each type.
