I want to downgrade Collabora

I updated to Collabora 6.2.9 and had a problem and needed to downgrade. I tried downgrading with the yum downgrade command and couldn’t do it.

Only the latest version is listed on the following site.

How do I revert to the old version of Collabora?

Same problem… no historic rpm keep on the collabora repository (big mistake) and after upgrade the collabora system stop working… seems that the only option it’s revert all the transaction from yum history or wait to the comunity aware of the problem and release a new update for the packages
