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) Active: failed (Result: exit-code) since Sat 2018-07-07 09:33:19 CDT; 12min ago Process: 3243 ExecStartPre=/usr/sbin/sshd -t (code=exited, status=255) Jul 07 09:33:19 warehouse systemd[1]: ssh.service: Service hold-off time over, scheduling restart.

Jul 07 09:33:19 warehouse systemd[1]: Failed to start OpenBSD Secure Shell server. 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.
