UMC GUI unusable after update - Interner Server-Fehler in "modules". UnicodeDecodeError:



[edit]This seems to be the same issue like in that post ucs-update-error-errate-175-nextcloud-schema[/edit]


after an errata update I encounter the following error when accessing the management console through the browser. Self services are still accessible but no features in the management gui.

UCS Version: 4.4-0 errata175 (Blumenthal)

Interner Server-Fehler in "modules".

Also univention-upgrade is throwing an error:

univention-upgrade –-disable-app-updates
Usage: univention-upgrade [options]

univention-upgrade: error: Extra arguments: ['\xe2\x80\x93-disable-app-updates']

Is there a workaround to get the management interface to work?




i have the same problem.
Is there any workaround for this problem



I can say Univention is working on this issue to provide a bug fix asap.They started analyzing this issue on our server.



Univention provided a fix. To upgrade log in via ssh and run

univention-upgrade --ignoressh --ignoreterm --disable-app-updates
