title: chmod 0775 is not changing permissions
body: <p>I have an Ubuntu larval AWS instance running and I am trying to change some permissions:</p>
  
  <p>When I visit my IP address for my newly installed site I get this warning:</p>
  
  <pre><code>The /var/www/seekadventure.net directory is not writable.
  Please chmod this directory and its contents to 0775.
  </code></pre>
  
  <p>So in the command line I try this:</p>
  
  <pre><code>ubuntu@ip-172-31-80-211:/var/www$ sudo chmod 0775 /var/www/seekadventure.net
  ubuntu@ip-172-31-80-211:/var/www$ ls -la
  total 20
  drwxr-xr-x  5 root     root     4096 Dec 14 05:32 .
  drwxr-xr-x 14 root     root     4096 Feb 27  2018 ..
  drwxr-xr-x 12 www-data www-data 4096 Feb 28  2018 laravel5.6
  drwxrwxr-x  5 root     root     4096 Dec 14 05:34 seekadventure.net
  drwxr-xr-x  3 www-data www-data 4096 Nov  8 13:32 utility
  ubuntu@ip-172-31-80-211:/var/www$
  </code></pre>
  
  <p>And as you can see from the <code>ls -la</code> command its still <code>root root</code></p>
  
  <p>Any ideas why the permissions are not changing?</p>
  
  <p>Update:</p>
  
  <p>While doing further investigation I saw the mount command could show more useful information:</p>
