Kubuntu Quick Setup

Follow these simple steps to start using Flatpak

  1. Install Flatpak

    To install Flatpak on Kubuntu 18.10 (Cosmic Cuttlefish) or later, 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

  2. 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 20.04 or later, run:

    sudo apt install plasma-discover-backend-flatpak

    On Kubuntu 18.04, you should run this instead:

    sudo apt install plasma-discover-flatpak-backend

  3. Add the Flathub repository

    Flathub is the best place to get Flatpak apps. To enable it, download and install the Flathub repository file or run the following in a terminal:

    flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

  4. Restart

    To complete setup, restart your system. Now all you have to do is install some apps!
