[Ubuntu] sudoer - achishis2/achishis2.github.io GitHub Wiki

Open the sudoers file: sudo visudo will open the /etc/sudoers file in GNU nano. If not, try export EDITOR="nano" and try sudo visudo again.

Add the below line to the end of file.

username ALL=(ALL) ALL Change the user name before you issue the commands

Then perform WriteOut with Ctrl + O. The editor will ask you for the file name to write into. The default will be /etc/sudoers.tmp:

File Name to Write: /etc/sudoers.tmp

Change that to /etc/sudoers:

File Name to Write: /etc/sudoers

A prompt will be displayed:

File exists, OVERWRITE ?

Or

Save file under DIFFERENT NAME ?

In both cases, press Y. Quit the nano editor with Ctrl + X.

Done!
