title: Ubuntu 16.04 message of the day not updating number of package updates.
body: <p>For the last month my amazon EC2 instance running Ubuntu 16.04 has had the same message of the day (motd):</p>
  <blockquote>
  <p>30 packages can be updated.</p>
  <p>10 updates are security updates.</p>
  </blockquote>
  <p>I have run the suggested commands:</p>
  <blockquote>
  <p>sudo apt-get dist-upgrade</p>
  <p>sudo apt-get update</p>
  <p>sudo apt-get upgrade</p>
  </blockquote>
  <p>After rebooting the instance the motd does not change. There are no packages to update, it is only the motd not updating.</p>
