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.

Yea i am useing a system called ubuntu and it keeps asking me for a password to instill updates or apps but i dont have a password on it how do i get it off


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.

After installing Ubuntu I logged out. Now is asks for a user name and passwork but I did't set any. I asked for it to automaticaly log on. How dos I fix it?


In Ubuntu 9.04 click on the main icon and select Restart.

- If Ubuntu is the only operating system on your computer you'll need to tap the ESC key as the system boots.

- If you have a
dual boot or multiple-boot system the menu should appear on its own.

- At the root level you'll get a boot menu. Select the one that says "recovery mode" and press Enter.

- Ubuntu continues to load until you reach the Recovery Menu.

- Arrow down to "

netroot

" which states Drop to root shell prompt with networking and press Enter.

- Now, at the root type "

password username

" (where username is the account whose password you want to change) and press Enter.

- You'll be prompted to

enter a new password

.

- You will not see the password or any evidence that you are typing.

- Retype the password. If both passwords match you'll have successfully reset your password.

- Press Enter to continue booting into Ubuntu.

hope it helps

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.

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.
