Backup Update mit OX auf 4.3 schlägt fehl aufgrund von fehlendem OX Service, slapd down



Hallo zusammen,
ich versuche meinen Backup inkl OX (Univention DC Backup 4.2-4) per univention-upgrade auf 4.3.x zu aktualisieren.

Der Master (Univention DC Master 4.3-2) ist bereits auf dem neusten Stand.

Das erste Update auf dem Backup auf den neusten Stand von 4.2.x funktioniert problemlos. Anschließend möchte der Updater auf 4.3.x gehen und scheitert dabei. Es wird angemerkt dass der Service OX nicht bekannt ist, anschließend ist der slapd down.

Habe ich hier ein grundlegendes Problem mit meinem Setup da der OX Service nicht im LDAP gefunden werden kann?

Viele Grüße

Hello Michael,

From the log output above I cannot say why it happend, but OX has been removed during the upgrade:

Entfernen von univention-ox-meta-singleserver (9.0.7-11A~ ...
Entfernen von univention-ox (9.0.7-11A~ ...

That the OX service couldn’t be found is not a problem.
The upgrade broke because of an unrelated package dependency problem.

You can try to fix the current package installation problem by running

apt-get install -f

and then continue the upgrade by running univention-upgrade again.

The critical question is however if your user data in the uninstalled MySQL server is still there (should be) and will be picked up by MariaDB, when installed (should happen).

If you made a backup before upgrading, then I suggest to finish the upgrade and afterwards install the OX App again. Then check the data in the OX database (user accounts, contacts, calendar entries). If that database migration failed, you should save the logs, then restore the backup and verify that the installation is OK before trying to upgrade again.

Before everything, check the state of the LDAP schema, see How do I check, if the correct LDAP schemes are registered? in Update to OX App Suite 7.10.0 for UCS 4.3



Hi Daniel,
thank you for your response. I was able to upgrade the Backup now to the latest version and OX is running as well.

I faced 3 issues during the upgrade.

  1. python-support had an issue during the first upgrade, so the status was iF, i fixed it with dpkg --reconfigure python-support. After that the upgrade could be continued
  2. during the upgrade ox was removed and also /etc/apache2/sites-available/ox.conf apache2 was failing to reload and the upgrade stopped again. a2dissite ox fixed the issue
  3. after the UCS update was done i picked up ox app suite again from the appcenter. The installation failed. The logs did not contain any useful information. a dpgk --reconfigure on the ox server package showed that OX wants openjdk-8 but openjdk-7 was installed (and the default jre). I changed the default to openjdk-8-jre and then ox could be installed again.

First tests are showing that everything is fine now. I can send an receive mails and also login into the appsuite.

Thank you again for pointing out the first issue, i would have search days why the ox service entry was missing in slapd :slight_smile:
