Binary package “update-motd” in ubuntu xenial

compliments pam_motd in libpam-modules

 .
 This package installs a script that immediately dynamically generates
 a message-of-the-day by running scripts installed in /etc/update-motd.d,
 in lexical order.
 .
 Other packages, or system administrators should symlink scripts into
 /etc/update-motd.d, pre-pending a 2-digit number to handle ordering.
 .
 The functionality formerly provided by this package is now integrated into
 pam_motd, in libpam-modules.
