Well thanx, the modification of the LDAP Entry did it and now the system is upgrading. Cross fingers.
OK, sorry, here comes the Error message maybe for other Users:
The following hosts must be upgraded to UCS 4.4-8 first:
Error: Update aborted by pre-update script of release 5.0-0
Starting univention-upgrade. Current UCS version is 4.4-8 errata1128
Both Systems are “domaincontroller_master”, well maybe that’s not a good idea? but worked quite well. I chose different Domains.
I wanted to separate the User-Base and LDAP
Both have the Version:
Yes, KVM was uninstalled before except of libvirt. And PostgresSQL updated.
Maybe you can give a short hint, how I should have set up a Environment with:
- DomainController master (internal Services, Samba, Nextcloud…)
- Standalone Server (no connection to the internal LDAP) with own Userbase for external Nextcloud an other external services
- Server with htproxy to deliver different Websites to different server.
Thanks for the quick and successful help. Univention is a really great system!
