title: fatal: remote error: Could not find Repository octocat/myapp
body: <p>I am using Git for the first time and just forked one open source project following <a href="http://help.github.com/fork-a-repo/" rel="nofollow">GitHub's instructions</a>.
  I am able to clone my fork on local computer but I get an error when running these commands:</p>
  
  <pre><code>$git remote add upstream git://github.com/octocat/myappname.git
  $ git fetch upstream
  </code></pre>
  
  <p><code>git fetch</code> gives me this error:</p>
  
  <pre><code>fatal: remote error: Could not find Repository octocat/myappname 
  </code></pre>
  
  <p>How can I resolve this error and fetch the project?</p>
