Description Dirk Wiesenthal

Reported by feedback (read bottom-up):

Die Ausführung des Kommandos appcenter/invoke_dry_run ist fehlgeschlagen:

URLError: &lt;urlopen error [Errno 101] Das Netzwerk ist nicht
erreichbar&gt;
    raise URLError(err)
  File &quot;/usr/lib/python2.6/urllib2.py&quot;, line 1159, in do_open
    return self.do_open(httplib.HTTPSConnection, req)
  File &quot;/usr/lib/python2.6/urllib2.py&quot;, line 1192, in https_open
    result = func(*args)
  File &quot;/usr/lib/python2.6/urllib2.py&quot;, line 369, in _call_chain
    '_open', req)
  File &quot;/usr/lib/python2.6/urllib2.py&quot;, line 409, in _open
    response = self._open(req, data)
  File &quot;/usr/lib/python2.6/urllib2.py&quot;, line 391, in open
    return _opener.open(url, data, timeout)
  File &quot;/usr/lib/python2.6/urllib2.py&quot;, line 126, in urlopen
    return urllib2.urlopen(request)
  File
&quot;/usr/lib/pymodules/python2.6/univention/management/console/modules/app
center/util.py&quot;, line 117, in urlopen

    zipped = StringIO(urlopen(json_url).read())
  File
&quot;/usr/lib/pymodules/python2.6/univention/management/console/modules/app
center/app_center.py&quot;, line 555, in sync_with_server

    cls.sync_with_server()
  File &quot;/usr/lib/pymodules/python2.6/unive 


Problem is obviously a simple network error. The App Center catches this error only on query() ("App Center is not reachable"), not when invoke_dry_run is called ("Internal module error! Traceback: ...").

It is unclear how the user got the list of all apps so that he could invoke_dry_run as the list is populated in the beginning and cached (so that sync_with_server is not called multiple times). Maybe a timeout?

To your question: simply open the specific app directly via the UMC overview, no via the appcenter app overview.

Should be handled with UCS 4.1
