title: Error: unable to locate package libpam-google-authenticator
body: <p>I'm having trouble setting up 2 factor authentication in Ubuntu Server 18.04.</p>
  
  <p>I'm following this tutorial: <a href="http://www.ubuntuboss.com/how-to-set-up-2-factor-authentication-in-ubuntu-server-18-04/" rel="nofollow noreferrer">http://www.ubuntuboss.com/how-to-set-up-2-factor-authentication-in-ubuntu-server-18-04/</a></p>
  
  <p>But on the first step when I try to install the package I get the package not found error as seen in the title.</p>
  
  <p><code>sudo apt-get install libpam-google-authenticator</code></p>
  
  <p>I have looked around to see if the package has been updated and goes by a different name and I am sure I have the most recent version of the package manager.</p>
  
  <p>Has the package changed or is there anyway  around this problem.</p>
