Apache fails to start on UCS 5.0 after some cleanup commands

Maybe related to this thread

https://help.univention.com/t/since-ucs5-dhcp-server-does-not-start-automatically/18767

but I’m not sure about it.

Apache2 fails to start with this error:

Okt 26 18:40:46 ucs-01 apachectl[1682]: AH00526: Syntax error on line 58 of /etc/apache2/sites-enabled/univention.conf:
Okt 26 18:40:46 ucs-01 apachectl[1682]: Invalid command 'WSGIScriptAlias', perhaps misspelled or defined by a module not included in the server configuration
Okt 26 18:40:46 ucs-01 apachectl[1682]: Action 'start' failed.
Okt 26 18:40:46 ucs-01 apachectl[1682]: The Apache error log may have more information.

So I enabled the module again:

root@ucs-01:~# a2enmod wsgi

and apache starts again.

Is there a list of the modules that are by default enabled for UCS 5?

Best, Bernd
