Answer 1

Edit:

On your terminal type:

pkexec nano /etc/sudoers

It will open the file and you can edit now. To save and exit the file, just press:

Ctrl+X

And it will ask you if you wanna save the file. So type: Y and Enter. Done!!!

Answer 2

we have to write -
pkexec visudo
And it will open the file and one need to change as previous if any made.
Then type Ctrl+X which will ask to save the file. So type: Y and Enter
