Comment 2 Florian Best 2016-09-13 15:24:59 CEST

Caused by Bug #40857.

@Dirk:
If you introduce new files you need to symlink this in the preinst e.g.:

if [ "$1" = "upgrade" ] && dpkg --compare-versions "$2" lt 1.2.3.4; then
    ln -s /usr/share/pyshared/univention/foo.py /usr/lib/pymodules/python2.7/univention/foo.py
fi

And please vote for Bug #28497!

Comment 3 Dirk Wiesenthal 2016-09-13 15:29:10 CEST

from debian/python-univention-appcenter.preinst:

if [ "$1" = "upgrade" ] && dpkg --compare-versions "$2" lt 5.0.22-1; then
        ln -s /usr/share/pyshared/univention/appcenter/database.py /usr/lib/pymodules/python2.7/univention/appcenter/database.py
fi

Version: 4.1-3 errata262 (Vahr)

Remark: sehr geehrte Damen und Herren,
diese Fehlermeldung erhalte ich an einem frisch installiertem UCS.
Bisher wurde UCS genutzt um über das APPCenter einige Apps zu installieren.
Anschließend wurde über die Console über apt-get update && upgrade geupdated.
Nach einem reboot reagiert das System mit dem beigefügten Fehler.
mit freundlichen Grüßen

Comment 10 Dirk Wiesenthal 2016-09-20 01:10:30 CEST

Fixed in
  univention-appcenter 5.0.22-17.223.201609200055

Currently, it looks like python-univention-appcenter failed to install for some reason (not yet known). But univention-appcenter-docker succeeded to install which caused the traceback as this package assumes python-univention-appcenter to be at the same version. Made this assumption explicit in debian/control.

Unfortunately, as the reason for all this is still unclear, QA can only verify that this fix solves the problem given that the theory about broken packages is correct.

Problem was Bug#42450. The fix applied here should indeed prevent this traceback.

Comment 13 Felix Botner 2016-09-20 17:21:36 CEST

FAIL - yaml

OK - univention-appcenter-* packages depend on 
     python-univention-appcenter (= ${source:Version})
OK - merged to 4.2-0
