linux ubuntu 12.04 help me

i cent get my root password so i cant get my network to work or anything :c

These instructions will allow you to change your password

OK, you need to boot into recovery mode, and you won’t have internet access whilst you’re doing this, so write this down.

Boot to recovery mode by shutting down your PC, then turn ON your PC and immediately hit and hold the “Shift” key … eventually you’ll be presented with the GRUB boot menu.

If available use the arrow keys to select a kernel version that ends with “(Recovery Mode)” … eventually you’ll be presented with some options.

Select the “Drop to a root shell” or “root prompt” or similar.

Now you’ll need to remount the root partition read/write, so run thiis command:

mount -n -o remount,rw /

next run this command:

passwd <username>

(replace with the name of the account whos password you want to change … such as “passwd mark”

You will be prompted to enter the new password twice.

once you’ve changed the password, shutdown the PC with:

shutdown -P now

(remembering Linux commands ARE case sensitive)

Now turn ON your PC again and let it boot normally.


It’s also covered here:

right um no here is the thing that i cant get passed :

system policy prevents modification of network settings for all users
an application is attempting to perform an action that requires privileges.
authentication as the super user is required to perform this action
password for root: ???

i dont know what the password for root is and is my notebook

If you only have a single account on the PC, the root password will be YOUR password.
