UCS 5.0 update check fails

When I run the pre-update-checks-5.0-0 script it fails with the following message:

The system can not be updated to UCS 5.0 due to the following reasons:

python_ucr_template_compatibility:
The following UCR templates are not compatible with Python 3:
         /etc/univention/templates/files/etc/ldap/slapd.conf.d/66univention-appcenter_app.acl
See <https://help.univention.com/t/17948> for information on how to proceed with each template.

The conflicting script is not listed in the pinned topic.

Can I delete this file? It is not part of any debian package.
