this is correct, cauldron is used as a playground for the devs, and if something breaks, it is at their discretion as to repair or ignore and work around it.
it appears for the moment that they are choosing to ingore it, so you must work around it, which is to reinstall via netinstall and online repos.
"Release" is a snapshot of "Cauldron", usually from a short period before release
When Mga9 is proposed, as upgrading from Mga8 to Mga9 is one of the many things needed to achieve, it will be attended to.
As a caveat, the instructions to upgrade from release to cauldron should only be followed for a short time after release, as effectively the two rpm streams are over 2 months apart at release, and there can be significant differences between them .
If you are planning to use Cauldron, it is recommended that you subscribe to the appropriate mailing list =>
