Completely Remove MySQL from Debian 8.3
<p>I literally tried everything.</p>

<p>Almost every answer in stackoverflow, I still can't remove MySQL</p>

<p>This is becoming a nightmare. I googled hell and back, I tried everything I found, from purging packages, autoclean, autoremove, removing directories, shutting down services, etc.</p>

<p>I still get errors.</p>

<p>I'm seriously thinking on a clean install.</p>
