OK, I found a workaround for this problem. This key is to remove all mysql installation BEFORE adding percona repos to sources lists. This should do the work: # apt-get remove mysql-server mysql-server-5.5 mysql-client mysql-client-5.5 mysql-client-core-5.5 mysql-server-core-5.5 mysql-common libmysqlclient18:i386 libmysqlclient18:amd64 # dpkg --purge libmysqlclient18:i386 # dpkg --purge libmysqlclient18:amd64 Now add percona repos, apt-get update, and apt-get install percona-server-server-5.5
