after updating Collabora to version 4.0.1.1 this morning I got a pop-up at the end of the update-installation process saying “Connection to module process failed”:
The Collabora App-Center screen hangs now in status “Aktualisiere Sitzungs- und Moduldaten”:
You should first take a look at the corresponding log files in /var/log/univention: appcenter.log , management-console-module-appcenter.log, manage-console-server.log, management-console-web-server.log.
Thank you for your feedback.
Checking the logs shows that a procces died at the end of the update (adconnector).
Rebooting the system fixed it for me, it seems Collabora was updated correctly.
