appcenter init fails: [Errno 104] Connection reset by peer
Last modified: 2019-01-03 07:23:37 CET
We received the following traceback, 4.0-2 errata193 (Walle). It occurs when opening the appcenter. The univention-updater makes a HTTP request to our repository but the socket connection is not accepted by the repository server. We should handle socket.error in the updater.

Later on, the appcenter receives a TCP RST (reset) package ("Connection reset by peer") and the TCP connection is terminated. There may be several reasons for this. Some of them are described in Bug 36044. Possible reason in this case: a TCP keep alive package has been sent to the repo server, but the repo server already dropped the TCP connection before and answered with a RST package. This may be caused by temporary routing issues.
Reported again, 4.0-2 errata240 (Walle)
