Apt-get issue.

Hi Luvers, how do I override suggested dependencies using apt-get which conflicts with already installed software that provides equivalent functionalities? For example: If I install phpmyadmin usign apt-get, it will also install apache2, and if I already have say nginx installed, it will remove it, and replace it with apache. But I want to keep nginx. How do I get apt-get to install phpmyadmin while keeping nginx? Thanks Daniel
