SSH System Status Check Error

The SSH server on this machine permits password-based login. A more secure way to log in is using a public key. Add your SSH public key to $HOME/.ssh/authorized_keys, check that you can log in without a password, set the option 'PasswordAuthentication no' in /etc/ssh/sshd_config, and then restart the openssh via 'sudo service ssh restart'.

$ cat /etc/ssh/sshd_config | grep PasswordA
PasswordAuthentication no
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication, then enable this but set PasswordAuthentication

$ sshd -V
unknown option -- V
OpenSSH_8.9p1 Ubuntu-3ubuntu0.7, OpenSSL 3.0.2 15 Mar 2022
usage: sshd [-46DdeiqTt] [-C connection_spec] [-c host_cert_file]
            [-E log_file] [-f config_file] [-g login_grace_time]
            [-h host_key_file] [-o option] [-p port] [-u len]

I keep getting the above despite having ran sudo mailinabox and now on v68. I also verified that PasswordAuthentication was indeed set to no, any ideas?

Update

$ sudo sshd -T | grep pass
permitrootlogin without-password
kerberosorlocalpasswd yes
passwordauthentication yes
permitemptypasswords no

I dug into the sources and ran sshd -T, will update again.

This solved it https://askubuntu.com/a/1440509/1587667

Check sudo vim /etc/ssh/sshd_config.d/50-cloud-init.conf
