How do I sudo without having to enter my password?

Question

I'm trying to setup sudo without no password but still I get prompted for password, I'm using ubuntu, here is the relevant line from the sudoers configuration file :

gandalf ALL=(ALL:ALL) NOPASSWD: ALL

Answer 1

I believe the correct line is:

gandalf ALL=(ALL) NOPASSWD: ALL

Put it in the end of the file - replace gandalf with the appropriate username. (To edit the file, run the command sudo visudo.)

Answer 2

I use the sudo group and have:

%sudo ALL=NOPASSWD: ALL

Answer 3

There is one note to mention. That line should be at end of the /etc/sudoers file.

Why: because some configuration lines from /etc/sudoers overwrite our line.

gandalf ALL=(ALL:ALL) NOPASSWD: ALL
