Remark: Hallo,
diese katastrophalen Kopano-Updates treiben mich noch in den Wahnsinn. Ist das direkte Kopano-Repo installiert, funktioniert de facto kein Update des UCS oder Kopano mehr so, wie
es soll.
Dies ist jetzt der neueste Streich, nachdem ich Kopano auf 8.3.0 bringen wollte.
Es ist völlig unklar, wie die Versionierung jetzt funktioniert, da Appcenter, App, Core usw fast nie kongruent sind.

I am a bit confused by this bug report - what should be fixed here exactly? The only similarity is that the tracebacks occur by calls to UMCP command "updater/updates/query' The title is about a "timeout in network connection", but the following errors did occur, according to the tracebacks:

Configuration error: timeout in network connection
Configuration error: <urlopen error _ssl.c:489: The handshake operation timed out>
Configuration error: _ssl.c:504: EOF occurred in violation of protocol
Configuration error: Die Verbindung wurde vom Kommunikationspartner zurückgesetzt
Configuration error: Network is unreachable

We should display an human readable error message if any Configuration/Network/etc error occurs which describes the situation (ssl error, connection error, error in configuration file) and what might caused this situation (e.g. proxy server is not available, ...) and what the user can do about this (check proxy / firewall settings, diagnostic-module-link, link to documentation, retry again later, ...).

This bug is not about the underlying issues/problems, which we probably can't cover but only about the error handling.

Comment 24 Dirk Wiesenthal

2018-06-18 15:13:22 CEST

Fixed it by catching UpdaterException during self.uu.get_all_available_release_updates()

The user is presented this:

'Error contacting the update server. Please check your proxy or firewall settings, if any. Or it may be a problem with your configured DNS server. This is the error message: %s

I also catch this during the initial "status" request. When trying to reproduce this, I got stuck when trying to load the "form". This error is actually absorbed by the JS code... We may have a lot more of these errors but only see those that lose their connection during "status" and "releases". But I am not sure.

I am unable to reproduce the error for QA purposes and also after talking to Dirk we could not reliably reproduce the error to test properly.

After discussion in a team meeting we decided to verify this bug after carefully analyzing the code. After all the code changes do not cause a big change in functionality other than catching an exception and wrapping it into a proper error message.
