I am trying to authenticate GCP VM root username with its password to add GCP VM in cloudera cluster.

When I select user root and type password, its giving authentication failed error.

Troubleshooting I make:

1. Permit root login is set to Yes: sudo vi /etc/ssh/sshd_config and Uncomment line: #PermitRootLogin prohibit-password and change it to yes
2. password Authentcation is “yes” in /etc/ssh/sshd_config file and restart sshd service in each VM: sudo service ssh restart , sudo service ssh status
3. Create password for root,Command: sudo passwd root

Pls help how to resolve password authentication error in GCP VM for Ubuntu 20.04 LTS.
