Comment 0 for bug 1103655

I found similar (but outdated posts (eg: https://bugs.launchpad.net/percona-server/+bug/877018)) on some other bug tickets, though they seemed to be marked as resolved. My apologies if I've missed something, but I do believe I've followed the installation instructions on a base system, so I'm confused as to why these errors would be occurring.

Thanks for your time.

Followed the instructions listed on this page exactly:
http://www.percona.com/doc/percona-server/5.5/installation/apt_repo.html

when running apt-get install command:

# apt-get install percona-server-server-5.5 percona-server-client-5.5
....

The following packages have unmet dependencies:
 percona-server-client-5.5 : Depends: libmysqlclient18 (>= 5.5.28-rel29.3-388.precise) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

More info when running aptitude install:

# apt-get install percona-server-server-5.5 percona-server-client-5.5
