title: Permission Denied (publickey)/fatal: The remote end hung up unexpectedly?
body: <p>So I started the production for a Jekyll site using the following commands,</p>
  
  <pre><code>$ git clone https://github.com/plusjade/jekyll-bootstrap.git USERNAME.github.com
  $ cd USERNAME.github.com
  $ git remote set-url origin git@github.com:USERNAME/USERNAME.github.com.git
  </code></pre>
  
  <p>After getting a local and github repo set up, I tried to send the changes to github,</p>
  
  <pre><code>$ git push origin master
  </code></pre>
  
  <p>to find this,</p>
  
  <pre><code>Warning: Permanently added the RSA host key for IP address '192.30.252.129' to the list of known hosts.
  Permission denied (publickey).
  fatal: The remote end hung up unexpectedly
  </code></pre>
  
  <p>What did I do wrong? What can I do to resolve this error?</p>
