Detailed Description
Fedora includes a flatpak repo definition for Flathub in the fedora-flathub-remote package. So far, this remote was filtered by an allowlist that only made a limited subset of software from Flathub available. We've been told that it is ok for us to remove the filtering and make all of Flathub available.
The filtering mechanism itself will still be there, and it will be possible for us to reinstate a filter via a package update, should the need arise in the future.
The Flathub remote is available to users who opt-in to enabling third-party software repositories in either GNOME Initial Setup or GNOME Software. Users who do not opt in will not see anything from Flathub.
In case of overlaps, GNOME Software will prefer Fedora flatpaks over rpms over Flathub flatpaks. It is always possible for the user to manually select a different source for individual applications.
Feedback
This change proposal has previously been discussed here: https://pagure.io/fedora-workstation/issue/300
Benefit to Fedora
More software will be easily available to Fedora users.
Additionally, the filtered Flathub has not been popular with users. Users have been confused and displeased that our Flathub remote contains only a small subset of Flathub, rather than the full Flathub. Dropping the filter will resolve this criticism.
Scope

- Release engineering: #Releng issue number
- No work needed
- Policies and guidelines: N/A (not needed for this Change)
- Trademark approval: N/A (not needed for this Change)
- Alignment with Objectives:
Upgrade/compatibility impact
Existing Fedora installations with a configured Fedora Flathub remote will pick up the new, permissive filter.
How To Test
When third-party software is not enabled in GNOME Initial Setup or GNOME Software, search results from Flathub should not appear in GNOME Software.
When third-party software is enabled in GNOME Initial Setup or GNOME Software, search results from Flathub should appear.
User Experience
When opening GNOME Software, all the applications that are available on Flathub will show up in search results.
Dependencies
No dependencies.
Contingency Plan
- Contingency mechanism: Reinstate the filtering we had in Fedora 36
- Contingency deadline: Beta
- Blocks release? No

Release Notes
The Fedora Flathub remote now exposes all content from Flathub, instead of only a small subset. Flathub is not enabled by default. To enable software from Flathub, turn on third-party software in GNOME Initial Setup or GNOME Software.
