Fedora Flatpak and SIG FAQ

Why do we need Fedora Flatpaks?

We need Flatpaks built and released by the Fedora project to be able to pre-install them on Fedora editions and variants such as Fedora Silverblue, Fedora Kinoite, etc.

Why not "just" use Flathub?

The following points make it legally and practically not possible to use Flathub to pre-install Flatpaks in Fedora:

• Flathub includes a mix of FOSS and proprietary software by default.
• Fedora Legal has not approved installing Flatpaks from Flathub by default in Fedora.
• Flatpaks packaged on Flathub do not necessarily follow the Fedora release process, which includes Beta and release freezes.

What are the advantages of Fedora Flatpaks?

Flatpaks made by Fedora have the following advantages:

• They are made from the same sources as the RPMs, and thus must meet the same constraints regarding FOSS licences as the rest of the packages in Fedora.
• They are tested and released in sync with Fedora releases and updates can be tested in Bodhi.
• They are built on Fedora infrastructure.

How are Fedora Flatpak made?

In Fedora, Flatpaks are made from the same sources as RPMs, but are built with a different PREFIX in order to install the application and its dependencies in /app (instead of /usr for RPMs).

The builds happen in the Fedora infrastructure using OSBS. See documentation in OpenShift Build Service - Flatpak.
