From my previous thread of a upgrade gone bad I have decided it was quicker and easier to start over and restore from a backup and followed Cool Solution - Single Server Backup and Restore and was successful with no errors during the restore process.
I performed a system diagnostic on the new DC Master and I get the error:
Critical: Check kerberos authenticated DNS update (on DC Master)
Errors occured while running `kinit` or `nsupdate`. `kinit` for principal ad$ with password file /etc/machine.secret failed.
From the thread Critical: Check kerberos authenticated DNS update (on DC Master) I checked with:
kinit --password-file=/etc/machine.secret $(hostname)\$ klist
The output is:
# kinit --password-file=/etc/machine.secret $(hostname)\$ kinit: Password incorrect # klist klist: No ticket file: /tmp/krb5cc_0
And for some system info:
# univention-app info UCS: 4.4-0 errata137 Installed: google-apps=2.3 pkgdb=11.0 prometheus-node-exporter=1.1 radius=5.0 samba4=4.10 4.3/admin-dashboard=1.2 4.3/prometheus=1.1 Upgradable:
Where do I go from here? I know @Moritz_Bunkus has worked on threads related to this.
