System information at Startup / ssh connect are gone Ubuntu 20.04

Traditionally , Unix motd would live in /etc/motd directory.RHEL still does that. Ubuntu on the other hand places login messages in /etc/update-motd.d/ directory.

$ ls /etc/update-motd.d/                                                        
00-header*     90-updates-available*  98-fsck-at-reboot*
10-help-text*  91-release-upgrade*    98-reboot-required*

Each of these scripts is responsible for dynamically assembling the whole message and provide specific parts.

It is still , however, possible to create a custom message in /etc/motd and place it into /etc/motd . File itself doesn't exist, but you just have to create it.

Here's how I tested it:

$ sudo sh -c 'echo  "THIS IS A TEST" >> /etc/motd'
