title: FIWARE IDM installation error
body: <p>I tried to install Fiware IDM in Ubuntu 12.04 from scratch (just only Ubuntu 12.04 was installed, no any more packages). I have followed the guide <a href="https://github.com/ging/fi-ware-idm/wiki/Installation-guide" rel="nofollow">https://github.com/ging/fi-ware-idm/wiki/Installation-guide</a></p>
  
  <p>Installation finished OK, but when I try to start fi-lab home page, <a href="http://localhost:8000" rel="nofollow">http://localhost:8000</a>, I've got the following error:</p>
