title: xdg-open : no method available even after installing xdg-utils
body: <p>I am using generator-angular-fullstack.
  On my local machine its working fine, I run </p>
  
  <pre><code> grunt serve
  </code></pre>
  
  <p>it starts server but in VPS it's failing </p>
  
  <pre><code>Warning: Command failed: xdg-open: no method available for opening 'http://localhost:9000'
  </code></pre>
  
  <p>and I have already installed xdg-utils</p>
  
  <pre><code> $ sudo apt-get install xdg-utils
   Reading package lists... Done
   Building dependency tree       
   Reading state information... Done
   xdg-utils is already the newest version.
  </code></pre>
  
  <p>Can any one explain me what I am doing wrong?</p>
