Root password in Ubuntu?
Ubuntu didn’t ask my password for root user during installation. So i guess as default Ubuntu has no password set for the root user. To gain root access , type followng command in shell.
sudo passwd
It will prompt to enter password that we set for the first user while installing Ubuntu. After that you are asked to type in the new root password twice. Finally, your root user has its own password.

I think the reason why Ubuntu does not ask for a root password during installation is that giving root a password creates a security weakness, in that if crackers know that they’re trying to crack a linux system, they will attack the root account first. If there’s no password for the root account, no one can log into the root account unless it’s through another administrative user account, which they will have to figure out the user name and password to.
By default, Ubuntu does not allow direct logging in to the root account.
thanks for the detail explanation ~
