[SOLUTION] How to disable 'sudo' asking for passwords in Ubuntu,Xubuntu or maybe Kubuntu

[White Boy]

You might have this problem because your parents or someone else changing to ubuntu or Xubuntu for instance.So here is the solution to disable sudo password prompts.(I am using Xubuntu 13.04)

1 Close your system or restart your system
2 Open GRUB menu by holding (SHIFT) on startup (not after you load the whole system)
3.1 Use your arrow keys and click on 'Advanced System Menu' or the 2nd line
3.2 Load Ubuntu,Xubuntu or Kubuntu with (Recovery Mode) which is the 2nd line
4 Choose 'root' and a command will be show underneath
5 Type "mount -o rw,remount /" without quotes
6 Type "sudo visudo" and find the following lines:
%admin ALL=(ALL:ALL) ALL
%user ALL=(ALL) ALL
%root ALL=(ALL:ALL) ALL (or something like these)

7 Change it to :
%admin ALL=NOPASSWD ALL
%user ALL=NOPASSWD ALL
%root ALL=NOPASSWD ALL

8 Exit it by hitting (CTRL+X) it will ask to save sudoers,delete the (.tmp) behind sudoers then hit (Y),if it ask for rewrite the file,do it

9 Type 'sync' at the command to confirm it,then type 'reboot' to reboot your system
10 After you load all your systems,try open terminal then type "sudo visudo" and see if it ask for passwords.

(I AM NOT RESPONSIBLE IF YOU BROKE YOUR SYSTEM,O THIS AT YOUR OWN RISK!)

Enjoy! :)

Like i said,do this at your own risk.This maybe useful if someone changed root password without notice.Or if someone lazy enough to put a very long passwords

Even with sudo password enable,it's not perfectly safe.If someone forgot 'root' password and don't want to change it.

Ex:I used to use Window 7 until someone change it to Xubuntu.I want to install Steam but i can't because Ubuntu Software Center keep asking for 'Root Authentication' but instead,i use Gdebi.To install Gdebi you nee Ubuntu Software Center or 'sudo'.

So,this tutorial is only for INNOCENT users.

So please understand,DO THIS AT YOUR OWN RISK.I AM NOT RESPONSIBLE FOR ANY LOSS OR DAMAGE SYSTEM.
