Migration of SUSE Manager 3.0 from SLES 12 SP2 to SLES 12 SP3 fails: dependency error

This document (7023048) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Manager 3

Situation

SLES 12 SP2 is out of support as of April 30th, 2018. However, SUSE Manager 3.0 is still supported (till late 2018). As a result, a migration to SP3 is expected in order to get support.

As a first step, in case it had not been carried out before, a migration of postgresql should be performed. Even after doing that, an error will be displayed when running "zypper migration" and selecting the option to only migrate the underlaying OS (SLES 12 SP2 to SLES 12 SP3):

vm-calzone:~ # zypper migration

Resolution

There was a wrong dependency in the release package. The fix is already part of the repositories, and the error should not be displayed any more. Should that still be the case, please refresh your repositories and try again.

Cause

A wrong dependency in the release package. It needed to be fixed through a maintenance update.
