body: <p>first of all I'm pretty new at this but i'm trying to follow along installing an open source crowd funding platform using a guide </p>
  
  <p><a href="https://github.com/danielweinmann/catarse/wiki/Pre-Configured-Catarse-Virtual-Box-using-Vagrant-%28Ubuntu-11.10-AMD64%29" rel="nofollow">https://github.com/danielweinmann/catarse/wiki/Pre-Configured-Catarse-Virtual-Box-using-Vagrant-%28Ubuntu-11.10-AMD64%29</a></p>
  
  <p>I installed vagrant and virtual box all fine including the download of the image.</p>
  
  <p>The problem is when I try to initialize it using the command:</p>
  
  <pre><code>vagrant init Ubuntu_11.10_amd64-Catarse-Master
  </code></pre>
  
  <p>The system responds with the following error:</p>
  
  <pre><code>Tiagos-MacBook-Pro:catarse_vagrant tiagomartins$ vagrant init Ubuntu_11.10_amd64-Catarse-Master

  <p>What am I doing wrong and what's the best approach to fix it.</p>
  
  <p>Thanks a lot!!</p>
