Quick heads up, the GNOME Nightly Flatpak repository is currently undergoing maintenance, during which you may notice that some applications are currently missing from the repo.
For a couple of months now we have been plagued by a few bugs that have made maintenance of the repo very hard, and CI builds were constantly failing due to a lack of available space. In order to resolve this we had to wipe the majority of the refs/objects in the repository and start again with safeguards in place.
As such, we are currently re-populating the repository with fresh builds of all the applications, but it may take a while. If you want to help with this, make sure your Flatpak manifests are up to date and build-able, and that you have set up a daily or weekly scheduled CI build in your project. Your app may not be changing, but the runtime might, and it’s good to be on top of possible API/ABI breaks.
Go to your project, Settings -> CI/CD -> Schedules -> New schedule button -> Select the daily preset.
If you are a user and seeing warnings while updating, don’t worry – you won’t have to do anything and updates will start working again transparently once the applications are available in the repository.
$ flatpak update
