Comment 3 Dirk Wiesenthal 2017-11-21 16:56:43 CET

Fixed in
  univention-appcenter (6.0.10-22)

Comment 4 Dirk Wiesenthal 2017-11-21 16:57:48 CET

(Just a better error message - and we do not receive 500, instead 418)

No, we don't.
From management/univention-appcenter/umc/python/appcenter/sanitizers.py:
 65 »   if isinstance(exc, (Abort, SystemError, AppcenterServerContactFailed)):
 66 »   »   MODULE.error(str(exc))
 67 »   »   raise umcm.UMC_Error(str(exc), status=500)

→ The status is 500 and should remain 500! Using 418 (or any of the other codes from python/appcenter/exceptions.py) would violate the HTTP semantics.

I meant the code sent to Univention after an installation. 500 is traceback, 400+ is defined in python/appcenter/exceptions.py. 418 is DatabaseConnectorError
