[Nut-upsuser] WALL not working on Debian 12

[Jim Klimov]

Maybe...ish - I haven't seen those for a while, but had few outages either.

Can you check if the updated (root) user profile or default profile(s)
under /etc mention `mesg n` or similar means of limiting broadcasts?

In your manual `wall` executions, do you see them in the same terminal that
sent the message, or on all terminals (GUI, SSH sessions)? As root or as
any user (as recipient and as sender)?
