Add this line at the end (change “jerome” to your username):
jerome ALL=(ALL) NOPASSWD: ALL
Ctrl-X to leave, save your changes, and you're done!
I have tried the above in an Ubuntu OS. It does not work and even with many other variations made to the sudoers file, I am always asked for a password when I execute sudo command.

Which version of Ubuntu are you using? It flawlessly works from at least 7.04.
Dec 30, 2008
8.0x Server Version
I will try your fix again on Friday.

I overlooked the fact that it must be at the end of the file. In my version, the last line of code gives all users in the admin group root access but with a password required. If your line precedes this, then the effects are undone by the last line of code because my user login is also a member (unintentional) of admin.

%sudo ALL=NOPASSWD: ALL
will also help... For me helped.

Not working 4 me man.I did exactly what you wrote.Here as you can see.Nothing happened.
# User privilege specification
root ALL=(ALL) ALL
caglar ALL=(ALL)NOPASSWD: ALL
# Uncomment to allow members of group sudo to not need a password
# (Note that later entries override this, so you might need to move
# it further down)
# %sudo ALL=NOPASSWD: ALL
# Members of the admin group may gain root privileges
?min ALL=(ALL) ALL

works on Karamic 9.10. Thanks....
Jan 14, 2010
caglar - you didn't place the "caglar ALL=(ALL) NOPASSWD: ALL" at the END OF THE FILE. It works for me under Karmic 9.10.
(What I actually did was place the %sudo line at the end of the file, and did a "sudo adduser sudo")

This is awesome, I tried it in Linux Mint 9 (Pretty much Ubuntu 10.04 with closed source packages, and a custom menu), and it works flawlessly. I hope it also works with package installs and programs like gparted.

but, but, why? you are destroying the nice security that it brings :S

Cant download anything or play voice messages on computer due to needing my password when I forgot a long time ago

This doesn't work! What are you talking about? HA! You DON'T know what you're talking about, you big fat $%^#ing $%^!

Correct. Eliminating sudo is the biggest security threat you can ever do to your system; especially a server. Awful practice.
Jan 4, 2011
Security? Maybe if your brother is attacking your system by slipping in while you go to the bathroom. If an attacker has access to YOUR account and you have root permission you are already screwed. What no password sudo gives to a desktop is that you can ease the burden of administration slightly. For a multi-user system it is a bad idea since the commands you issue as root will affect the work of others. Thus, the password prompt is a fine indicator that you should think twice.
Jan 15, 2011
The password prompt is indeed a good indicator of the severity of your actions. Nullifying the use of a password is a security risk. While entering your password every time is cumbersome, it is possible to set the password timeout higher (add Defaults passwd_timeout=10 to /etc/sudoers using the command sudo visudo)*. This would dissuade intrusion, unless the attacker has physical access. No measure of security can overcome PEBKAC.

thanx cafehunk for your suggestion! I was stuck with this issue for a while..

works in ubuntu 11.04 beta2

Consider keeping an open shell/editor session su'd as root while you experiment so that you don't accidentally lock everyone out of being able to sudo (and consequently have no way of reverting the change!). #LFMF

Although there is a small security issue with removing passwords from sudo, there is a much bigger security issue... passwords themselves. Password re-use is a bigger problem than password entrapy. Most people have less than 5 passwords but use 100+ websites and other PCs.
My home PC has a password to log in with a keyboard, but as soon as I find a way to do log in with a dongle, I'm going to remove password access all togeather. All servers such as SVN and PostgreSQL on my PC are OS user based.

Works fine........ gr8 Tip. Helped me alot

faltou antes chmod +w /etc/sudoers
acrecenta a linha
e chmod-w /etc/sudoers

Works with Ubuntu 11.04 Desktop i386.

PS remember to change it back, otherwise you have a security issue. If you read this tip in the wrong place maybe your IP address and who knows your login name as well are now out there.
Would you leave your hall door open while playing in the back garden with your dog? - hm, maybe you don't have a garden; maybe you don't have a dog ; maybe you don't have a hall door :-)

The technique work on OS X, too. Maybe it works on all *nix-like OSes with /etc/sudoers files? Anyway, OS X has prototype lines in the file clearly commented like, "Uncomment to allow all people in group wheel to run all commands". There are other ones for per user, etc. Makes it easy to eliminate security. Who cares about security, anyway? Don't you leave your front door open? i do.
Sep 12, 2011
Very important! Add it at the END of the file!
It doesn't work if you add it at the top.
Nov 13, 2011
thank you..it works fine
Nov 15, 2011
Thanks, very helpful. I use an Ubuntu virtual machine to record screencasts and with this I don't have to enter my password all the time during recordings.
Dec 13, 2011
NEVER edit /etc/visudo directly, as charles suggested. If you do something wrong, which creates a syntax error, then you can't use sudo to change it back... Use visudu to change that file, it checks for syntax errors and warn you if needed. (One syntax error is if there is no empty line after the last line, but there are also other syntax errors.)
A better idea is to specify those commands you want to run without password, and have sudo ask for password for other commands.
username ALL=NOPASSWD: /usr/bin/apt-get

It worked for me .. thanks
Aug 5, 2012
@visudo : that never works for me. it's NOPASSWD=ALL or nothing.
Sep 12, 2012
Or you could just do what I did and write a package managing script that injects NOPASSWD=ALL into /etc/sudoers for the duration of functions then changes /etc/sudoers back to original upon exit.
Dec 31, 2012
I was able to run it on Ubuntu 12.10 to do you should
1. create a script inside the directory /etc/sudoers.d and name the file as XX_someName where XX is a numeric value. Eg 99_aptget
2. inside the file include the line
someUser ALL = NOPASSWD: /usr/bin/apt-get
3. change the mode to 0440
eg. chmod 0440 99_apt_get
You should now be able to run it.

Not working for me :-( How do you use it? I set the user dimi, but when I login via ssh I cannot sudo.. :-(
bash-4.1$ sudo --help
bash: sudo: command not found
Mar 6, 2013
I think I just made it with another user. I still dont know why the user dimi cannot execute the sudo comand but the other user does. However, this solution is OK for me so far.
