Kubuntu Quick Setup

Install Flatpak

To install Flatpak on Kubuntu 18.10 (Cosmic Cuttlefish), simply run:

      $ sudo apt install flatpak
    

With older Kubuntu versions, the official Flatpak PPA is the recommended way to install Flatpak. To install it, run the following in a terminal:

      $ sudo add-apt-repository ppa:alexlarsson/flatpak
      $ sudo apt update
      $ sudo apt install flatpak
    

Install the Discover Flatpak backend

The Flatpak plugin for the Software app makes it possible to install apps without needing the command line (available on Kubuntu 18.04 and newer). To install on 18.04, run:

      $ sudo apt install plasma-discover-flatpak-backend
    

On Kubuntu 20.04 or later, you should run this instead:

      $ sudo apt install plasma-discover-backend-flatpak
    

Add the Ramatak Inc. repository

      $ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
      $ flatpak remote-add --if-not-exists ramatak https://download.ramatak.com/ramatak.flatpakrepo
    

Restart
