Hello everyone,
i’ve updatet my xwiki installation to 12.9, a few versions ago, there began some problems with the update wizard, could not update the flavor anymore. I’ve uploaded some packages then and did a manual update. That worked so far, everything is working. I found out, that the problems came from closed firewaoll ports. I think, it’s workig everything fine now, just one little strange problem left now:
If i go to the extension updater, the extension updater is telling me, that theree is XWiki Standard Flavor Versopm 12.7.1 as an old version, Version 12.8 would be installed. If i click to “de-update”, it will install Version 12.8 again and the updater tells me again, there is 12.7.1 installed. Why nothing about Version 12.9 here?
if i check dependencys it looks like this:
XWiki Standard Common Application12.7.1 (in Wiki Home)Version 12.9 is installed as dependency
Wiki Application12.7.1 (in Wiki Home)Version 12.9 is installed as dependency
Menu Application12.7.1 (in Wiki Home)Version 12.9 is installed as dependency
Help Center Application1.5.2 (in Wiki Home)Installiert
I don’t know, what to do now and how to solve this situation.
Please help 
Regards, Benjamin
Edit: If i check in the extions tab, it’s telling me an error:
Extension [org.xwiki.platform:xwiki-platform-distribution-flavor-mainwiki/12.9] is not allowed on namespace [null]. Allowed namespaces are: [wiki:xwiki]
