Enable root login via ssh not working?

I want to enable root login via ssh. So I add the ligne 'PermitRootLogin yes' to ssh config file '/etc/ssh/sshd_config' :

---

Protocol 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key

SyslogFacility AUTH
LogLevel INFO

It could be a couple of things:

1)If you are trying to log in using a password you will need to add:

PasswordAuthentication yes

in the config file. (Should only use this method for setting up ssh keys initially)

2)You have not properly set up your SSH keys.

3)The ssh port is being blocked by the firewall.

In ubuntu 20.04 root has no default password causing SSH connection to fail with "Permission denied, please try again".

To solve this you must set a password. Run

sudo passwd

and enter your password twice.
