[Bug 1558270] Re: [Ubuntu 16.04] No automatic/regular update of motd

[Dimitri John Ledkov]

This message is not cleared at the end of "apt fullinstall" but they are
cleared when update notifier runs again. It is a cosmetic issue.

It is wrong to assume that update-notifier is not needed on the server,
it implements reboot notifications, upgrade notifications, security
notifications as well as propagates the data into
landscape.canonical.com (or self-hosted instance) for remote monitoring
and upgrades.

Title:
  [Ubuntu 16.04] update-notifier motd doesn't update with apt full-
  upgrade

Status in update-notifier package in Ubuntu:
  New

  Logging in into Ubuntu shows the MOTD (message of the day) which again shows how many packages still could be updated.
  ---------
  For example:
  Welcome to Ubuntu Xenial Xerus (development branch) (GNU/Linux 4.4.0-11-generic s390x)

   * Documentation:  https://help.ubuntu.com/

  7 packages can be updated.
  0 updates are security updates.
  ---------
  After "apt-get update" and "apt-get upgrade", then rebooting the system, this message still appears although now no package is available to update. That is sometimes confusing a little bit.

  Here the config of /etc/pam.d/login: 
       session    optional   pam_motd.so motd=/run/motd.dynamic
       session    optional   pam_motd.so noupdate

  I tried to comment the second line but nothing happened.
  And I also tried to delete "/run/motd.dynamic", hoping that this file will be created again with updated information. But it does not.

  After apt-get upgrade, apt-get dist-upgrade or aptitude the status of the number of updateable packages should be recalculated.

  These messages are generated by some Python script belonging to the package update-notifier-common.
  To get rid of these annoying messages just remove the package update-notifier-common, though it is designed to be used on desktop systems and is therefore not necessary on server systems like System z.
