Why I'm not asked to set a password for Root when Installing Ubuntu?

Solution 1:

You aren't supposed to add a password for the root account. We have something called the sudo mechanism to handle that. Instead, you add users to the admin account. All those users can then run commands or programs as root by running sudo command for terminal commands or gksu command for GUI apps to run as root, such as gksu gcalctool though that example obviously makes no sense)

When you're being asked for a password when installing things, etc, it is your own password you should use. This way, it is possible to enable others to do administrative tasks without having to share passwords and keys. It is also configurable to allow someone to run a specific command as root, but not others, but you won't normally touch that.

The first user you created is by default the admin account.

Solution 2:

You can use root privilege to run commands/applications by adding sudo , gksu key word on start of any command. like sudo gedit and it will ask you admin password
Also for switch terminal to root level, use sudo su.

In any case, you can change root password by following procedure:

1. Start a terminal (by pressing Ctrl+t)
2. Run sudo -s to accessing root privilege
3. Run passwd root for changing root password. It will ask you new root password.
4. Now you can login using root and if you open a terminal, you can see # in prompt.
