UCS 4.4-9 e1278 to UCS 5.0-2 upgrade error: newer version Kopano is needed (latest version installed)

UCS - Univention Corporate Server
#1

We have 2 UCS 4.4-9 errata1278 servers, a primary and a backup.

UCS backup server has latest Kopano Core (8.7.25.0-1), Kopano WebApp (5.3.0.0-1) and Z-Push for Kopano (2.6.4) installed. App center shows there are no more updates.

When trying to upgrade the primary UCS server to UCS 5.0-2 it errors out with:

The system can not be updated to UCS 5.0 due to the following reasons:

default_master_packages:

The Kopano App is or was installed in your domain.
A newer version of the Kopano App is needed in order to update to UCS 5.0.
Kopano and Univention are currently working on providing this new version
as soon a possible.

The App Center on this primary UCS sees the Kopano apps installed in the domain and shows the correct (latest) versions of these apps.

This feels like a dependency issue. Anyone with an idea how to resolve this?

The message is misleading and needs to be updated. You need to execute what is given in the following paragraph: univention-remove --purge kopano4ucs-udm. The new Kopano App version automatically installs and registers the components that were previously part of the kopano4ucs-udm package

Will it automatically install and register the components even if Kopano has already been installed on the backup server?

#5

Yes, the latest Kopano Apps for UCS 4.4 will do that, independent of the server role where they are installed.
