@rabbifede Hello again, and welcome back.
We have not yet reached our next designated stable rpm state; hence have yet to create a stable repository for this release. The downloads page indicates this vai a new table recently added/updated.
But our current testing channel is nearing the stable state as we are now in the Stable Release Candidate phase there with 5.0.13-0:
I.e. 5.0.13-0 is an RC8 release. And we have some pending changes that should emerge soon as 5.0.14-0: which - at least initially - is looking to be our next stable release. But only time will tell: as we have yet to receive show-stopper reports on 5.0.13-0 issues that have yet to receive pending fixes.
As above, it’s at our end and is a development timing issue - plus I need to work on our back-end maintenance so that I can at least publish empty signed repos for target OS version to avoid this cosmetic but never-the-less disconcerting error. That inevitably crops up as our release time-line differs/drifts from our upsteam of openSUSE. But note that openSUSE Leap 15.6 is our main target now. And will be receiving the first stable rpm once we have its fitness confirmed in the testing channel first.
Hope that helps, and note that this ‘missing repo’ does not hold up any other available updates: only the rockstor rpm which will come-into effect as soon as that repo actually exits.
