title: Ubuntu Apache: "Module php7 does not exist"
body: <p>I am trying to upgrade PHP 5.5.9 to PHP 7 on my DigitalOcean Ubuntu 14.04 machine.</p>
  
  <p>I've read many tutorials and articles how to do it, but each of them misses something. For example, somewhere they say you must <code>sudo a2dismod php5</code> then <code>sudo a2enmod php7</code>. The problem is that I always get this message</p>
  
  <pre><code>$ sudo a2enmod php7
  ERROR: Module php7 does not exist!
  </code></pre>
  
  <p>Does someone one how to resolve this problem, please?</p>
  
  <p>Thanks in advance.</p>
