Univention Bugzilla – Bug 34004
invoke_dry_run may take longer than apache's ProxyTimeout
Last modified: 2014-01-31 14:00:34 CET
Apache answers with 502 after 300 seconds. tools.umcpCommand('appcenter/invoke_dry_run') may take longer than that to finish (slow internet connection when updating the repositories), showing an "unknown error" to the user. It is impossible to continue after that leaving the app uninstalled. Reported in the forum.
