Comment 34 for bug 1570678

I just tested percona-xtradb-cluster from Xenial-proposed on ppc64el and I am still getting the root password error.

Unable to set password for the Percona Server "root" user │
 │ │
 │ An error occurred while setting the password for the Percona Server │
 │ administrative user. This may have happened because the account already │
 │ has a password, or because of a communication problem with the Percona │
 │ Server daemon. │
 │ │
 │ You should check the account's password after the package installation. │
 │ │
 │ Please read the │
 │ /usr/share/doc/percona-xtradb-cluster-server-5.6/README.Debian file for │
 │ more information. │
