Comment 29 for bug 1657256

"I have removed percona-xtradb-cluster-5.6 from this bug as in Trusty we have percona-xtradb-cluster-5.5, and in xenial (and above) we have percona-xtradb-cluster-5.6. I've created a separate bug for Percona in xenial (and above): #1693765."

Given that percona-xtradb-cluster-server-5.6 replaces percona-xtradb-cluster-server-5.5 and the same bug is being fixed in both packages (even though they happen to have different names) the work should be tracked in one bug report. Splitting the work up into two separate bug reports is unnecessary and creates confusion for both users and the Ubuntu Stable Release Updates team.
