Remark:
Hallo,
ich habe mir nach der fehlerhaften Deinstallation von OpenXchange weitere Pakete deinstalliert. Wenn ich mich auf dem Server direkt anmelde kommt die Fehlermeldung "Esi sit ein
schwerer Fehler aufgetreten. Sehen Sie bitte in den Protokolldateien von KDM nach weiteren Informationen oder benachrichtigen Sie Ihren Systemverwalter" ... ;-((((
Ich versuche über die Paketverwaltung (Remotezugriff auf die UMC funktioniert noch, leider nicht mehr der AppCenter) ...

Reported again, 4.1-0 errata1 (Vahr)

I found a way to reproduce this:
Install univention-demo-app on a DC slave. When the dpkg- installation messages occur in the progressbar stop the LDAP server on a DC master. After the installation of the app the
UMC session gets renewed. After this the traceback occurs.

Remark:
Fehler tritt auf, nachdem das Updaten von 4.04 auf 4.1.0 durchgeführt und fehlgeschlagen ist. Ich habe wegen verschiedener Fehler den Server manuell neu gestartet und jetzt
funktionieren mehrere Komponenten nicht mehr. Unter Anderem die Anmeldung am Samba...

Fixed in
  univention-appcenter 5.0.19-47.104.201602090155

Improved error_handling, raise better exceptions

Comment 11 Florian Best

This looks way better!
YAML: OK

Further improvements for the future could be:
* HTTP Status = 503
* Close AppCenter frontend on such an error (as it looks especially ugly after the initial failed query).
* Abort-Error translations
* First-Time-Appcenter-Dialog should not be displayed if LDAP-Server is down
* Bug #40629
