Let the sudo command not enter the password

First execute the following command (the command is used to modify the/etc/sudoers file):

$ sudo visudo then put the #%sudo All=nopasswd:all line at the beginning of the # and move it to the end of the file as follows: # Uncomment to let members of the 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 and then Execute the following command: $ sudo adduser ' whoami ' sudo

You can do it.

The first step is to make the user subordinate to the sudo group do not need to enter a password when executing the sudo command.

The second step is to add yourself to the sudo group.

Please refer to the Ubuntu Chinese forum post "Let sudo not enter password" on the 40th floor.
