During the pre-update script, I have the error :
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/11univention-ldap-usercert_schema (package: univention-ldap-usercert)
See <https://help.univention.com/t/17948> for information on how to proceed with each template.
old_packages:

Error: Update aborted by pre-update script of release 5.0-0
Can I safely remove the univention-kdm, univention-x-core, univention-dansguardian (I have squid installed) ?
and for the extension, openvpn, guacamole have been remove for more than 1 year on the server
