The above screenshot is the snippet of the Sudoers file, displaying the root user having the access to elevated privileges. I deleted that line where it says “root ALL=(ALL) ALL”, so that I am removing the sudo privileges to the root user.
But after doing that, I am still able to avail the sudo privileges (example: installing a package, creating a user as a root user).
My doubt is how is it happening in the background when I have deleted the root user from Sudoers file and I am still able to sudo privileges for the root user.
