title: Ontotext GraphDB installation on linux debian (Jessie)
body: <p>I'm trying to install Ontotext GraphDB free on a debian jessie server.
  I've downloaded graphdb-free-8-1-1.deb file but when I'm typing the command</p>
  
  <pre><code>sudo deb -i graphdb-free-8-1-1.deb
  </code></pre>
  
  <p>as suggested in the quick start guide (<a href="http://graphdb.ontotext.com/documentation/free/quick-start-guide.html" rel="nofollow noreferrer">http://graphdb.ontotext.com/documentation/free/quick-start-guide.html</a>), I get the following message :</p>
  
  <pre><code>sudo: deb: command not found
  </code></pre>
  
  <p>It's seems that it has something to do with the /etc/sources.list file. Do I have to insert a line in this file ? how ?</p>
  
  <p>Thanks for your help.</p>
