If you’re the only user on your system, you don’t need to be prompted every time you run the sudo command.
Add yourself to the sudoers file.
# create a new file sudo visudo -f /etc/sudoers.d/users
Add this line.
# add your username username ALL=(ALL) NOPASSWD:ALL
Exit and try again.
# exit out and login again exit # try to sudo again sudo -i # there's no password prompt for sudo this time
