Tutorials/Flatpak

Flatpak is a solution for creating sandboxed software builds for GNU/Linux systems. You can find more information here. To learn about creating flatpaks, see our flatpak tutorial.

KDE Apps on Flathub

We are building release versions of most KDE applications and distributing them on Flathub.

The "app store" or software center in many distributions (usually Discover on KDE Plasma) is able to install Flatpaks. You can follow the Flathub guide to setup Flatpak and Flathub on your system.

You can then search for a KDE application and it should offer to install the Flatpak version.

You may also directly open the flatpakrepo file with Discover or your otherwise favorite software center.

Here's how to install a Flatpak application from the terminal:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.kde.okular

Using Flatpak Applications

Once a flatpak package is installed, it can be run with

flatpak run org.kde.okular

and be updated to the latest version with

flatpak update org.kde.okular

Nightly KDE Apps

We are also building "nightly" versions of most KDE applications and distributing them from the kdeapps remote at https://distribute.kde.org. The latter builds the latest source code of the application, so expect some unstable development quirks; on the bright side, if you find one, you get to tell the developers so they can fix it!

You can install it with the following flatpakrepo file: https://distribute.kde.org/kdeapps.flatpakrepo

Here's how to install a Flatpak application from the terminal:

flatpak remote-add --if-not-exists kdeapps https://distribute.kde.org/kdeapps.flatpakrepo
flatpak install kdeapps org.kde.okular

If you added both the Flathub and kdeapps repos and do not specify from which repo you want to application to be pulled, the flatpak command-line tool will prompt you which one you want, something like:

flatpak install okular
