Flatpak

Flatpak is a modern method of distributing Linux applications. The applications run inside a sandbox environment and don't rely on packages or environment provided by your Linux distributions. Read more about Flatpak.

Stable Release

You can install Flatpak with the latest stable release of Kontact from Flathub.

To install it, run

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

Run Kontact:

flatpak run org.kde.kontact

Nightly Builds

Nightly Flatpak builds of Kontact are available in the KDE Flatpak repository. You can use them to test if your bug has been fixed, to checkout some latest features before they are available in the next stable release or to simply just help us with testing the development branch and making sure we did not break anything.

Add the Flathub and KDE Flatpak repositories:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak remote-add --if-not-exists kdeapps-testing --from https://distribute.kde.org/flatpak-apps-testing/kdeapps.flatpakrepo

And install the Kontact Flatpak:

flatpak install kdeapps-testing org.kde.kontact

Run Kontact:

flatpak run org.kde.kontact//master

You can omit the //master part if you only have the nightly Flatpak installed. But if you also have stable Kontact Flatpak from Flathub you need to specify the branch, otherwise Flatpak will run the stable one.
