title: unresolved host / Upgrade 12 to 14 Ubuntu/ Net Connection fine through browser
body: <p>I recently upgraded to 'Trusty' i.e. Ubuntu 14.04. I tried pinging google.com through the terminal. </p>
  
  <pre><code>ping google.com
  ping: unknown host google.com
  </code></pre>
  
  <p>I tried the following:</p>
  
  <pre><code>sudo apt-get remove --purge resolvconf &amp;&amp; sudo apt-get install --reinstall resolvconf
  </code></pre>
  
  <p>to remove and reinstall the resolv config, but to no avail. </p>
  
  <p>Then I found the official bug here: <a href="https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1308378" rel="nofollow">https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1308378</a>
  I tried to do the following as instructed there:</p>
  
  <pre><code>cd /etc
  sudo ln -s /run/resolvconf/resolv.conf
  </code></pre>
  
  <p>But it gave an error: </p>
  
  <pre><code>ln: failed to create symbolic link ‘./resolv.conf’: File exists
  </code></pre>
  
  <p>Internet works fine through my firefox browser. In fact, I'm writing this question through the same system. </p>
  
  <p>I set additional DNS servers in the WiFi settings to the google DNS servers:</p>
  
  <pre><code>8.8.8.8, 8.8.4.4
  </code></pre>
  
  <p>But to no avail. </p>
  
  <p>Please help. </p>
