The UCR variable `keycloak/server/sso/fqdn` is missing from univention-management-console-web-server.univention-config-registry which is most likely the reason why some update tests are failing.
added a missing UCRV to the univention.conf apache2 config. This previously caused the config not to update when Keycloak was being installed after the join script has run, which lead to wrong headers. univention-management-console.yaml 09e53bedf55e | fix(umc): add keycloak UCRV to trigger for univention.conf univention-management-console (12.0.33-7) 09e53bedf55e | fix(umc): add keycloak UCRV to trigger for univention.conf
OK: apache2 config listens to changed of keycloak/server/sso/fqdn OK: YAML OK: Package build OK: Cherry-pick to 5.1, 5.2 OK: Jenkins 5.0-7 OK: Jenkins 5.2 OK: Jenkins 5.2 upgrade Verified
