I'm not sure if this is new or not, but it is the first time I have noticed it. When I ssh into an ubuntu workstation I now see:
Expanded Security Maintenance for Applications is not enabled.
Enable ESM Apps to receive additional future security updates.
See https://ubuntu.com/esm or run: sudo pro status
Is this ad a new thing or have I just not been paying attention?
Remove the execute bit from these two files and you shouldn't see the message again: sudo chmod -x /etc/update-motd.d/88-esm-available /etc/update-motd.d/91-contract-ua-esm-status
