Ubuntu Change Root Password

Ubuntu has Two different passwords a root password and a user password. When you say you do not have a password you mean a user password. The System is looking for a root password. It asked you for one when you installed the system. If you do not know it the only way I know to get around it is to reinstall. Ubuntu and most linux distro is free. Download one and make a cd or dvd then reinstall if you do not have one.

Hi

"Yes" for installing any flash or any type or program you might Administrator password.As default Ubuntu has no password set for the root user. To gain root access you have to type in your own user password. This is the password you set for the first user while installing Ubuntu. To manually set a password for the root user, type in the following in the shell:


sudo passwd

After that you are asked to type in the new root password twice. Finally, your root user has its own password.

Now you enter the your password to install the flash or any other program.

Read this tutorial, here.

Hi Daniel,
Ubuntu has the root account locked by default. If you need to run as root, you use sudo username (This is recommended)
If you want to have a root shell on an Ubuntu system (It is not suggestedsuggested)
sudo -i
This is equivalent to the "su -" command sudo -s
This is equivalent to the "su" command

First of all, try this:
Username: root
Password: root

Second of all, you only specified that you had Vista. If you manually installed Ubuntu, then you must've specified a Username and Password during the setup.

If none work, then go ahead and format the Ubuntu partition, then re-install Ubuntu. This time, try to remember the Username and Password.
