Changing your root password on an Ubuntu server.
You can change your root password on your Ubuntu server via SSH with some simple commands.

2. When logged in, if you’re using the root user you just need to type;
sudo passwd root
If you already have root permissions, you will not need to type ‘sudo’. You can also change the ‘root’ to be a different user if you’ve set one up.
