SailfishOS:Chum GUI Installer works on any SailfishOS release ≥ 3.1.0 and on all CPU-architectures.
Note that, before software can be build for a SailfishOS release at the SailfishOS-OBS, Jolla must create a corresponding "download on demand (DoD)" OBS-repository. It may take a little time after a new SailfishOS release is published before the corresponding "DoD" repository is being made available, during which installing the SailfishOS:Chum GUI application by the SailfishOS:Chum GUI Installer or updating the SailfishOS:Chum GUI application by itself on a device with the new SailfishOS release already installed does not work, because the SailfishOS:Chum GUI application cannot be compiled for this new SailfishOS release at the Sailfish-OBS, yet; consequently this is always the case for "closed beta (cBeta)" releases of SailfishOS. In such a situation one has to manually download the SailfishOS:Chum GUI application built for the last prior SailfishOS "general availability (GA)" release (e.g.,from the SailfishOS:Chum repository), then install or update the SailfishOS:Chum GUI application via "pkcon install-local <downloaded RPM file>", and hope that there is no change in the new SailfishOS release which breaks the SailfishOS:Chum GUI application; if there is, please report that soon at the SailfishOS:Chum GUI application's issue tracker:

Because this is a SailfishOS release independent `noarch` package, you might as well use an RPM file built for any other SailfishOS release or CPU architecture at the SailfishOS-OBS, or the most recent RPM file at OpenRepos:
