Disabling the password needed for
sudo for a specific user is very easy in Ubuntu. This method applies to Ubuntu 16.04, but probably also other versions of Ubuntu and maybe even other distros.
First, run the following command:
Note: If this is the first time you’re running this command, you’ll most likely be presented with a list of editors to choose from. Choose the one you’re most comfortable with.
Then enter the following line at the end of the file:
user ALL=(ALL:ALL) NOPASSWD:ALL
Make sure to replace user with the username of the user you want to allow using
sudo without entering a password.
