title: Accidental change of ownership of some root directories in Ubuntu 14.04
body: <p><strong>(Accidental) Action</strong></p>
  
  <p>Hi, I am not very well versed in Linux but using Ubuntu for more than a year.</p>
  
  <p>Couple of days back I accidentally changed the ownership of my root folder while changing ownership of another non-root directory. I am not sure but as far as I remember, I executed <code>sudo chown -R root:root /bin</code> accidentally.</p>
  
  <p><strong>The Consequences</strong></p>
  
  <p>Now I am unable to do anything that requires <code>sudo</code>. This is the error I am getting while performing any such task:</p>
  
  <p><code>max@max-ThinkPad-T430:~/Desktop$ sudo chown -R root:root /bin
  sudo: /etc/sudoers is owned by uid 1000, should be 0
  sudo: no valid sudoers sources found, quitting
  sudo: unable to initialize policy plugin</code></p>
  
  <p><strong>Question</strong></p>
  
  <p>What's the solution to bring back the <code>sudo</code> working exactly as it was before the incident.</p>
