title: Apache wont restart after I enable SSL
body: <p>Once I a2enmod the ssl module and restart apache I get the following error:</p>
  
  <pre><code>Restarting web server apache2
  AH00548: NameVirtualHost has no effect and will be removed in the next 
  release     /etc/apache2/ports.conf:14
  (98)Address already in use: AH00072: make_sock: could not bind to address
  [::]:443
  (98)Address already in use: AH00072: make_sock: could not bind to address
  0.0.0.0:443
  no listening sockets available, shutting down
  AH00015: Unable to open logs
  Action 'start' failed.
  The Apache error log may have more information.
  </code></pre>
  
  <p>To stop it I can either disenmod or comment out the following module lines in the ports.conf file:</p>
  
  <pre><code>Listen 80
  #&lt;IfModule mod_ssl.c&gt;
  #    Listen 443
  #&lt;/IfModule&gt;
  &lt;IfModule mod_gnutls.c&gt;
      Listen 443
  &lt;/IfModule&gt;
  # vim: syntax=apache ts=4 sw=4 sts=4 sr noet
  </code></pre>
  
  <p>Any help would be much appreciated</p>
