This is a bug with Percona-Server and not percona-toolkit actually.

So, perl-DBD-MySQL requires libmysqlclient.so.16 which is provided by mysql-libs, Percona-Server-shared-compat and Percona-Server-shared-55.

Now, mysql-libs is out of picture if Percona is installed since it is obsoleted.

That leaves, Percona-Server-shared-55 and Percona-Server-shared-compat.

The candidate in this situation to be installed is Percona-Server-shared-compat (since Percona-Server-shared-51 and Percona-Server-shared-55 have conflicts) but Percona-Server-shared-51 gets installed and causing the issue.


The fix is to remove the duplication between Percona-Server-shared-compat and Percona-Server-shared-51.

It can be done as:

    1. Creating a separate Percona-Server-shared-compat for 51 as suggested here - lp:893860 but without libmysqlclient.so.16  (to avoid conflict).

    2. Remove Percona-Server-shared-51, and provide a common Percona-Server-shared-compat with  libmysqlclient.so.{12,14,15,16}.
