#1. Open the /etc/sudoers file (as root, of course!) by running:
sudo nano /etc/sudoers
#2. At the end of the /etc/sudoers file add this line:
username ALL=(ALL) NOPASSWD:ALLYou can configure sudo to never ask for your password.
Open a Terminal window and type:
sudo visudo
In the bottom of the file, add the following line:
$USER ALL=(ALL) NOPASSWD: ALL
Where $USER is your username on your system. Save and close the sudoers file (if you haven't changed your default terminal editor (you'll know if you have), press Ctl + x to exit nano and it'll prompt you to save).
As of Ubuntu 19.04, the file should now look something like
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
