The problem here is different from the shared-compat issue.

mysql-libs is a combination of our Percona-Server-server and Percona-Server-shared.

However, this conflict is only marked in Percona-Server-shared but not in Percona-Server-server.

Workaround: Manually remove mysql-libs before installing.

Fix: Add mysql-libs in the provides (if that is a way to record the conflict) or some other way.
