title: Unable to push code on github?
body: <p>I have successfully pushed one app code onto github.
  I had set up the ssh key and added it to github.</p>
  
  <p>But then I started working on another app and tried to push it onto github using:</p>
  
  <pre><code>git remote add github git@github.com:user_name/demo_app.git
  git push -u github master
  </code></pre>
  
  <p>Then I got the following error:</p>
  
  <pre><code>Permission denied (publickey).
  fatal: The remote end hung up unexpectedly
  </code></pre>
  
  <p>I have also tried changing the name of the remote Git repository but that didn't work too.</p>
  
  <p>I tried $ssh -v git@github.com to get more information and this is what i got.</p>
