Seems that you have pretty mess in your current packages and available repositories. You seem to have installed various mysql packages from all these repositories: Centos, art, Percona. Also you seems to have Percona-Server-shared-56 already installed, while you cannot mix 5.5 and 5.6 packages. Try to uninstall all the existing MySQL and Percona Server packages first, and then re-try installing Percona Server 5.5. ---

Thanks, your advice helped me! The problem was the mysql-libs package which presumably had been installed by something else. yum remove mysql-libs yum update ---
