Nelson,

This is the way i do it, maye there's an other way.

Ubuntu has no set password for the root user. The defult root password is your own user password, the password you set for the first user while installing Ubuntu.

These are the steps to change the password -

1.Applicatons > Accessories > Terminal.
2.In the new window that opens write "sudo passwd".
3.the system will ask for the new root password.

If you are using Unbuntu, then by default there is no password set for the root user. In order to log onto root, you have to initially create your own password. this password will be the password that you set for the first user that you created while installing the OS.
To manually set the password type "sudo passwd" into the command shell and then confirm your password.

How to change the root password in Linux


You need to boot the machine into runlevel 1. This will reboot into a secured shell and allow you to run passwd. This will in turn allow you to set the password for the root account.

To get into runlevel 1, either type telinit 1 in a terminal or command prompt on a Linux machine, or reboot the machine and do the following:

When the splash screen for the OS appears hit F12. This should take you to the grub bootloader. Highlight the entry for the kernel version you are using and press "e". This will allow you to edit this entry. At the end of the line just add the "1" character to it and save the changes and boot into that kernel. The OS should boot directly to a command prompt. At this time you should be the root user. Simply run passwd and enter in a new password, reboot the machine and log in as root using the password you just entered.

I got a computer that has ubuntu 11.04/linux and it has a user name and password set but I can't figure out how to reset it.


When Ubuntu boots, select Esc for the boot menu (Grub) and select recovery mode. Ubuntu will then boot w/o asking you for a password signed in as root. Type passwd USERNAME and it will reset your password. source:http://in.answers.yahoo.com/question/index?qid=20110608030342AArlwua

Root Password


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

HP Pavilion w. Vista, am trying to open Ubuntu for first time since install, but it wants a user name and password. Have tried all the combos from Windows, keep getting wrong password or name message. Also...


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.

Upgrade Ubuntu Error


-While booting your grub bootloader, press "e", enter the edit mode.

-Press "e" on the first line.

-(hd0,0) Change the last 0 to a 2, so it reads: (hd0,2).

-Press ‘b’ to boot.

Good luck.
