[solved] After uninstalling OX Appsuite and updating to UCS 4.4-7 errata 989 no start of apache 2

After uninstalling OX Appsuite and updating to UCS 4.4-7 errata 989 no start of apache 2

After update to UCS version 4.4.7 errate989
no access to the UMC was possible anymore.

According to Univention Update Log (/var/log/univention/update.log apache 2 could not start anymore.
Unfortunately I can not copy the appropriate lines from the Updater.log or upload Updater.log because I lack the rights as a new user in the forum.

After trying apache 2 with the command “invoke-rc.d apache2 start”, the log reports an error on line 222 of apache 2.conf.

There was no further information in the error.log of apache2

Is there any way to reinstall with a correct confirguration of apache 2 and eliminate possible configuration errors.

I have already tried: ucr-commit
The problem were two broken symbolic links, on two already deleted configuration files of the OX-Appsiute.
