Following the release of Uyuni 2022.03, some users noticed problems bootstrapping new clients 
To address those issues, we just re-released 2022.03 with changes that allow bootstrapping again. The re-release should be available in the openSUSE mirros in a couple of hours maximum.
When avaible, just follow the usual procedure for minor upgrades  . If you still did not update to 2022.03.
We re-released instead of releasing a patch, as this way all environments will easily get the fix, both those that were updated already to 2022.03, and those that will be updated after this fix is released.
Please note: Such changes will disable the Salt bundle for Salt SSH, including for WebUI bootstrapping. This is transparent for you, but also means Salt SSH clients using Salt 3000, will still use Salt 3000.
The release notes were fixed to remove this feature as part of 2022.03. Salt Bundle for Salt SSH This feature will be back in 2022.04.
Sorry about the inconvenience.

Remember that Uyuni will follow a rolling release planning, so the next version will contain bugfixes for this one and any new features. There will be no maintenance of 2022.03
