Installing on Linux using Flatpak

Flatpak is a distribution agnostic software utility for building and distributing desktop applications on Linux. It allows to install third-party Linux applications without having to add repositories or deal with dependencies.

Installing Flatpak

First, you will need to install Flatpak itself; to do that, go to https://flatpak.org/ and install the software, choosing your distribution and following the instructions.

For example, to install Flatpak on Ubuntu 18.10 (Cosmic Cuttlefish) or Ubuntu 19.04 (Disco Dingo), simply run:

$ sudo apt install flatpak

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

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

Installing the Software Flatpak plugin

Flatpak plugin for the Software app makes it possible to install apps without the command line. To install it, run:

 $ sudo apt install gnome-software-plugin-flatpak

Adding the Flathub repository

Flathub is the best place to get Flatpak apps. To enable it, run:

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

Once you have installed Flatpak, restart your system.

Visiting Flathub and installing ONLYOFFICE Desktop Editors

After the restart, follow the command to install ONLYOFFICE Desktop Editors:

flatpak install flathub org.onlyoffice.desktopeditors

Alternatively:

Go to Flathub at https://flathub.org/apps/details/org.onlyoffice.desktopeditors
Install ONLYOFFICE Desktop Editors using the Install button (when offered, open the file with Software Install (by default) and follow further instructions).

Uninstalling Desktop Editors

Uninstalling Desktop Editors will permanently delete associated local data, including application configuration and preference files, cached data and temporary files, local service files and user-generated data used for application startup, andother files and records created by the application during its use. This action is irreversible. Once uninstalled, the data listed above cannot be recovered unless you have created a backup prior to uninstallation. If you wish to preserve any of this data, please back it up manually before proceeding with the uninstallation.

To remove ONLYOFFICE Desktop Editors from your machine, use the following command:

flatpak remove org.onlyoffice.desktopeditors

Say ‘y’ to ‘Is this ok [y/n]:’

Regularly, there shall remain no residual files after removal using common system methods. However, if any, run the following command to remove anything that may still remain:

sudo rm -rf ~/.var/app/org.onlyoffice.desktopeditors
