How to Enable Flatpak and AppImage Support in Ubuntu 23.04

Last updated: May 12, 2023 — 1 Comment

This simple tutorial is going to show you how to add both latpak and AppImage package format support, while Ubuntu does not support them out-of-the-box.

Enable Flatpak Support in Ubuntu

Ubuntu is focusing on the native deb and snap support. The developer team has officially announced that they won’t support Flatpak out-of-the-box.

However, user has the freedom of choice to use any other source sources, including Flatpak.

1. To enable Flatpak support, first press Ctrl+Alt+T on keyboard to open terminal, and run command:

sudo apt install flatpak

Type user password (no asterisk feedback) when it asks and hit Enter. In case the command does not work, run sudo apt update first to update package index.

2. (Optional) Then, you can choose to add the Flathub repository, the standard repository that contains tons of applications as Flatpak. To do so, run command:

flatpak remote-add --if-not-exists flathub

When done, log out and back in to apply the variable environment change.

3. Finally, you can either go to and install any Flatpak application, by running the flatpak install command in bottom of its web-page.

Or, install a local .flatpak (or .flatpakref) file by running command:

flatpak install ~/Downloads/file_name_here.flatpak

Enable AppImage Support in Ubuntu

AppImage is a non-install package format for Linux. Like some .exe or .msi files, user can directly click run .AppImage file to launch applications. Though, the ‘allow executing file as program’ option has to be enabled first in file ‘Properties’ dialog.

Ubuntu does NOT support AppImage out-of-the-box, due to switch to fuse3, while the file format requires the classic fuse2.

So enable AppImage is also easy. Just open terminal (Ctrl+Alt+T) and run command to install the fuse2 library:

sudo apt install libfuse2

After that, right-click on your AppImage file and click ‘Run’ to launch the application after enabled ‘allow executing file as program’ and enjoy!
