Problem: OpenProject blocks the upgrade to UCS 5


The upgrade to UCS 5 failed, and the /var/log/univention/updater.log shows you, that the app OpenProject blocks the upgrade.

The system can not be updated to UCS 5.0 due to the following reasons:
The update to 5.0 is currently not possible,
because the following Apps are not available for UCS 5.0:
* OpenProject

Your system may currently have OpenProject version 12.0.7 installed. Upgrading the application will actually make the problem worse, because the Docker container for OpenProject version 12.2.2 will install incorrectly on UCS 4.4-9 and will not start.

Docker logs shows some like:

The OpenProject vendor itself is responsible for this.


For UCS 4.4-9 still use OpenProject version 12.0.7


The solution here is to remove the app, upgrade UCS, and then reinstall the app in the latest version.


Uninstalling usually does not remove the configurations, but I recommend making a snapshot or backup before you start.

1. Remove the app OpenProject with:

univention-app remove openproject

2. Start the upgrade for UCS


With the upgrade to UCS 5, postgresql is also upgraded and the dependency for newer OpenProject versions is fulfilled.

3. After the successfully upgrade to UCS 5, install the app OpenProject

univention-app install openproject

The above command will install the application in the latest available version for UCS 5, but if you want to install a specific version, this article will be helpful.
