This tutorial provides all the required steps to install Flatpak as well as downloading, installing, and running LibreOffice on Clear Linux.

Please visit the Flatpak website for more information about Flatpak and how to use it.

Before you begin

This tutorial assumes you have installed Clear Linux on your host system. For detailed instructions on installing Clear Linux on a bare metal system, visit our bare metal installation tutorial.

Install Flatpak on your host system

Flatpak is included as part of the bundle desktop. To install the application, log in to your user account and enter the following command:

$ sudo swupd bundle-add desktop

Install and run the LibreOffice Flatpak image

Application developers have the option to bundle their applications using Flatpak to allow the installation of a single distribution of their application on different distributions of Linux, including Clear Linux. Flatpak provides a list of applications available through Flatpak.

Download and install the Latest LibreOffice Flatpak

To get the latest version of the LibreOffice Flatpak repository, either download it here or you can enter the following command:

$ curl –O -L

The command downloads the latest LibreOffice.flatpak and saves it in your current directory.

Once the download is complete, the next step is to install LibreOffice along with the runtime environment LibreOffice needs to execute. As mentioned on the Flatpak website, with the release of Flatpak 0.8.0 and LibreOffice.flatpak 4.2.4, you no longer have to specifically install the runtime required to execute LibreOffice since it will automatically install the runtime referenced in the LibreOffice.flatpak file.

To install LibreOffice run the following command:

$ sudo flatpak install --bundle LibreOffice.flatpak

The output from this command will look similar to the following.


You will be prompted to install the runtime environment if it is not already installed. Type y to allow this task to execute.
