wall is built with systemd/logind support, the modern replacement for utmp. Make sure your sessions are listed in `loginctl` output (with a TTY). If they are not, make sure you have libpam-systemd installed and systemd-logind is running. There might still be an issue with openssh not forwarding the TTY to logind; if you are affected by this, then `wall` cannot do anything about this.

I'll wait a bit for you to show that it's really `wall` that is the problem here, and not something else; otherwise I'll close this report. Best, Chris
