Need to know on what server role this was installed on and have the installation/updater and the join log. Very likely this was from a pre-release test installation. Role: domaincontroller_master (In reply to Daniel Tröder from comment #1) > Very likely this was from a pre-release test installation. No, it was reported yesterday. The NotFound exception is catched. I had this error only in the situation where the self-service memcache instance wasn't running - it was actually a connection error. That was fixed by r78602 on 2017-04-03 in univention-self-service (2.0.16-2). Same error here at two different setups. First setup: UCS: 4.2-0 errata15 App Center compatibility: 4 Installed: nagios=3.5 radius=4.0 self-service=2.0 ucsschool=4.2 v1 Second setup: UCS: 4.2-0 errata10 App Center compatibility: 4 Installed: mailserver=11 self-service=2.0 Both systems are fresh installed with UCS 4.2. No special configuration. Installed self-service in UMC app center. Access to both system for debug is available. Thanks for the test system. The memcached service was indeed not running. r79360: fix memcached command line r79362: advisory Package: univention-self-service Version: 2.0.16-5A~4.2.0.201705161137 Branch: ucs_4.2-0 Scope: errata4.2-0 memcached should not run as root!

The logging is not necessary as the traceback is logged which contains all the infos. I was certain I once had coaxed more information from libmemcache, but I cannot reproduce it. I probably confused it with a postgres error. r79390: remove unnecessary logging r79391: update advisory -> 2.0.16-7A~4.2.0.201705171158 OK: error handling OK: YAML |
