title: CUPS 2.0 lpstat and lpinfo commands return "Bad file descriptor"
body: <p>I have installed cups 2.0 on my Ubuntu box. I installed from source. When I type the first few commands in the <a href="https://www.cups.org/documentation.php/doc-2.0/options.html" rel="nofollow noreferrer">CUPS manual</a>  it returns the message Bad file descriptor. Here is an example</p>
  <pre><code>VPCZ12V9E:~$ sudo lpinfo -m
  lpinfo: Bad file descriptor
  VPCZ12V9E:~$ lpstat -p
  lpstat: Bad file descriptor
  </code></pre>
  <p>Please suggest why this is happening? It implies to me that I have a problem. I have not tried adding a printer yet. I have only installed CUPS 2.0.</p>
