Debian and dependencies

I have an debian 9.3 with added percona repo. Percona packages works fine, but i can’t install some packages from main debian repo such as postfixadmin because default-mysql-client dependency required for it. This is meta package which installs MariaDB 10.1 client and apt suggest to remove percona server and percona client.


# apt install postfixadmin
