title: Download GHDL with Ubuntu 16.04
body: <p>Good evening,</p>
  
  <p>I wanted to download GHDL so I did this command :</p>
  
  <blockquote>
    <p>sudo apt-get install ghdl</p>
  </blockquote>
  
  <p>But I have a message who said that no version of the GHDL package is disponible, but that it exists in the database.
  And they said that the package GHDL doesn't have a version who can be installed.</p>
  
  <p>I try this command too :</p>
  
  <blockquote>
    <p>sudo apt-get install ghdl gtkwave</p>
  </blockquote>
  
  <p>But I get the same message. So, my question is : how can I download GHDL? I'm on Ubuntu, with the 16.04 version. </p>
  
  <p>Thanks in advance for any help.</p>
