i’ve succesfully installed percona-server-5.7 on Ubuntu 14.04 (Trusty). All was looking good untill i turn on postfix service. My postfix require “postfix-mysql” package to work, because i store “domains” “mailboxes” ect. in mysql databse.
So as it turn out when i do “apt-get install postfix-mysql” this comand is removing “percona-server-5.7” and other percona’s package. And whan i do “apt-get install pecona-server-server-5.7” the “postfix-mysql” is removed.
I was able to install postfix-mysql alongside PS 5.7.16:
root@postfix:~# dpkg -l |egrep -i ‘percona|postfix’
ii percona-release 0.1-4.trusty all Package to install Percona gpg key and APT repo
ii percona-server-client-5.7 5.7.16-10-1.trusty amd64 Percona Server database client binaries
ii percona-server-common-5.7 5.7.16-10-1.trusty amd64 Percona Server database common files (e.g. /etc/mysql/my.cnf)
ii percona-server-server-5.7 5.7.16-10-1.trusty amd64 Percona Server database server binaries
ii postfix 2.11.0-1ubuntu1 amd64 High-performance mail transport agent
ii postfix-mysql 2.11.0-1ubuntu1 amd64 MySQL map support for Postfix
root@postfix:~# cat /etc/os-release

So I wonder what could be the problem in your case. Can you please share the output after you ran ‘apt-get install postfix-mysql’? Can you also share output of “dpkg -l | egrep -i ‘percona|postfix’”
