title: Ubuntu unable to locate package
body: <p>I have installed devstack for openstack on ubuntu system. I am trying to install <code>quantum-lbaas-agent</code>. I get the error <code>Unable to locate package</code>. I tried changing the the sources list in the <code>/etc/apt/sources.list</code> file. I was unable to edit it and hence I changed permissions to <code>777</code> for <code>sources.list</code>. I ran <code>sudo apt-get update</code> after changing the permission. I still get the unable to locate package error. I tried running <code>sudo apt-get upgrade</code> as well. Still there was no progress.</p>
  
  <p>Here is the output of <code>sudo apt-get install quantum-lbaas-agent</code>:</p>
