so if i'm reading this correctly, maybe the issue is the percona package from the repo is older then the latest ubuntu package?

====================

However clearly i'm not sure just trying to point out a few ideas..
Thanks,

I just had a brain storm to prove my issue i ended up adding this to

*** Can be used as a work around until its resolved with the Percona Repo ***

/etc/apt/preferences,

Package: *
Pin: origin repo.percona.com
Pin-Priority: 610

Which pins the Pecona Repo sources for packages which a relevant to this issue, and did a apt-get update and tried reinstalling the packages successfully.

Or if your lazy like me try pasting this

cat >> /etc/apt/preferences <<EOF
Package: *
Pin: origin repo.percona.com
Pin-Priority: 610
EOF

Enjoy

So the timeline is complete:
A few people (myself included) posted on an old closed issue regarding this problem: https://bugs.launchpad.net/percona-server/+bug/1103655

This bug is confirmed for quantal and precise platforms. The source of the problem, as it has been explained in some of the comments, is that the official repo's libmysqlclient18 is being chosen over our version. The official repo Depends: on mysql-common, which installs a my.cnf that we with to avoid.

We will solve this by upgrading the epoch: in our packages for that versions, which will cause our versions to be chosen. This will have the same effect as pinning our repo.

Thanks for your reports!
