Public bug reported:
I keep trying to set up external SSH access using openssh server on my
18.04 system and it throws back this error
sudo service ssh status
● ssh.service - OpenBSD Secure Shell server
Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset:
enabled)

I was in the process of uninstalling the openssh-server and ssh packages
and was prompted to start a bug report. If it's in error, just let me
know. My ssh config file is all default except for
passwordauthentication = yes. I've toggled that to default as well, and
still get the same error.
