Hi and Happy New Year to everyone!
I’m running univention for years now with need for only basic services (LDAP, samba, windows domain controller). Last update in september failed due to some problems:
disk_space (fixed)
minimum_ucs_version_of_all_systems_in_domain (should be fixed too)
keycloak_migration (maybe still open?)
Missing disk space in /boot was fixed successfully (univention-prune-kernels).
System still running without issues after reboot
The problem with the minimum version was an old (non existing) memberserver (named ucs-dashb / 5.0.3). I manually removed these instances in the configuration.
Unfortunately, I don’t fully remember the next steps completely, but I did an “apt autoremove” for not longer needed packages, which must have broken the system.
After I reinstalled all packages which were uninstalled with autoremove and rebooted the system I could access the webportal again, but cannot login ("invalid credentials).
“kinit administrator” is working, but “id administrator” is failing with “no such user”.
“univention-ldapsearch” returns “ldap_bind: Invalid credentials (49)”, so there seems to be a problem with ldap.
Luckily “udm users/user list --filter uid=Administrator | grep DN:” is returning a valid user now (after reinstalling the autoremoved packages), so I can try to reset credentials.
How can I check afterwards (in case of success), that everything is ready for the upgrade?
