title: git clone - fatal: remote error: access denied or repository not exported
body: <p>When I try to perform the following command, <code>git clone git://github.com/mainDir/dirA</code>,  I get the following error:</p>
  
  <pre><code>&gt; git clone git://github.com/mainDir/dirA
  Cloning into 'dirA'...
  fatal: remote error: access denied or repository not exported: /8/nw/87/1e/aa/2154553/2154553.git
  </code></pre>
  
  <p><code>git://github.com/mainDir</code> is a <code>private repository</code></p>
  
  <p>If I try to use github for the mac... I see the message <code>Cannot find repository</code>.</p>
  
  <p>For sure the problem is in my desktop (client part) because I know how to reproduce the problem:</p>
  
  <p>1) <code>git clone repo</code> on my desktop (it works)<br>
  2) <code>rm -rf repo</code><br>
  3) <code>git clone repo</code> and I get the error</p>
  
  <p>How can I fix this problem?</p>
