title: Can't install php5.6
body: <p>I had some problems with php so I decided to remove it and install it again. This is how I removed it: </p>
  
  <pre><code>sudo apt-get purge php.*
  </code></pre>
  
  <p>But maybe this was somehow wrong because now I can't install something different than php7. This is how I try to do it:</p>
  
  <pre><code>sudo add-apt-repository ppa:ondrej/php
  sudo apt-get update
  sudo apt-get install php5.6

  Note, selecting 'php5.6-json' for regex 'php5.6'
  Note, selecting 'php5.6-common' for regex 'php5.6'

  <p>Does anyone have an idea why this is happening? I've been trying to solve it for the last couple of hours but my head will explode soon.
