Comment 3 for bug 908620

The Percona Server install need to conflict with mysql-libs. Percona-Server-server-5* is the package that triggers the error, however having Percona-Server-shared-5* conflict would also serve this purpose since it's required for Percona-Server-server-5*.

Trying to make Percona-Server-server-5* with stock mysql-libs, for example by moving the errmsg.sys files to Percona-Server-shared-5* and just depending on mysql-libs won't work because of the different versions of the messages that would appear.
