Hello,

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’m using this instruction to install percona-server: [url][https://www.percona.com/doc/percona-server/5.7/installation/apt\_repo.html[/url]](https://www.percona.com/doc/percona-server/5.7/installation/apt_repo.html%5B/url%5D)

So the question is, how to install percona server with postfix-mysql package?
