Flatpaks mostly don't use your shared libraries, they ship their own. Flatpak also brings better security with a sandbox that doesn't let the app access all your system when it doesn't need to, and a permissions system. Flatpak also uses repositories, called remotes, the biggest one is of course Flathub. So, most distros out there should have flatpak preinstalled, but if you run Ubuntu or an official Ubuntu flavor, Debian, or Arch, you might want to install it yourself. On Ubuntu or Debian: sudo apt install flatpak For any distro: https://flathub.org/setup But this only gives you command line access to flatpak. If you're a more graphical sort of person, you might want to add support for your app store: FOr GNOME software, the package is often called gnome-software-plugin-flatpak, and for Discover on KDE, it's generally plasma-discover-flatpak. Next, you'll need to add a repo to be able to install flatpaks easily, without downloading a file manually each time. The biggest one everyone should use is FLathub, it has virtually every flatpak ever made. sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo THEMING: There are a bunch of themes available on Flathub, that you can find typing flatpak search theme If the theme you use is in there, you can just install it from here, then, you select it in GNOME Tweaks, and you run: flatpak update If your theme isn't available from Flathub, though, you'll need to tell flatpak it needs to use your specific theme. To do this, you can either run a command, or use a graphical application. sudo flatpak override --env=GTK_THEME=NAME OF YOUR THEME. But that's not enough, we also need to give flatpak access to the directory where your themes are located, namely the .themes directory: sudo flatpak override --filesystem=$HOME/.themes For GTK4/Libadwaita apps, open your .bash-profile file in your home directory. At the end, add this line: export GTK_THEME=NAMEOFYOURTHEME Save the file, and then log out and log back in for all the changes we made to be applied. All your GTK apps should now use the right theme, whether they're using libadwaita, flatpak, or both. PERMISSIONS Now let's see how you can change permissions. To manage them, you can use Flatseal on GNOME and KDE, but KDE also has a permissions page in the settings. Generally, permissions are correctly set, but if you feel an app shouldn't have access to something, you can toggle that thing off, and if you feel an app SHOULD have access to something, you can toggle it ON. BROWSER INSTALL Installing flatpaks is just a one click operation from your graphical app store, but if you like to browse for apps in your web browser, you can also start an install straight from there. There's an extension for Firefox and CHromium based browsers called Flatline. https://addons.mozilla.org/en-US/firefox/addon/flatline-flatpak/?ref=itsfoss.com https://chrome.google.com/webstore/detail/flatline/cpbniogoilfagmcoipghkgnpmdglfmjm COMMAND LINE BASICS: install: flatpak install APPNAME Uninstall: flatpak remove APPNAME Update: flatpak update Cleanup: flatpak uninstall --unused List installed flatpaks: flatpak list Search for flatpaks: flatpak search Run an app: flatpak run COMPLETE_APPNAME Kill an app: flatpak kill COMPLETE_APPNAME Repair: flatpak repair
