Overview

Flatpak is a distro independent method for packaging and distributing Linux software.

Using software distributed by Flatpak has a couple of distinct advantages:

Software that is not compatible with current system libraries will still work when packaged as a Flatpak
Delta upgrades make upgrades more network efficient in the long-term

There are some other considerations to be aware of:

Flatpaks are not updated as part of your system updates, they must be updated separately
Only themes that have been ported to Flatpak will work with Flatpaks
A large set of shared runtimes will need to be installed to use Flatpaks

Installing Flatpak

Flatpak is available in the Manjaro repos as flatpak and can be installed with your favorite package manager or using the command

pamac install flatpak

Using Flatpak

Managing Flatpaks via Discover

One way to manage your Flatpaks is with the application Discover from the KDE project. You can install the package discover with your favorite package manager or the command:

Tip

Managing Flatpaks via Gnome Software

One way to manage your Flatpaks is with the application Gnome Software from the Gnome project. You can install the package gnome-software with your favorite package manager or the command:
