I am new to Ubuntu. And as while editing anything in visual studio code, I had to enter password. so for that I tried to change in sudoers file but after that I am unable to find what happened and also getting error like below.

I used the command to change i

sudo nano -w /etc/sudoers

after which i pressed ctrl+x

/etc/sudoers: syntax error near line 26 <<<
sudo: parse error in /etc/sudoers near line 26
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin

Thank you.

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!!!

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

This should open visudo up in nano.

$ export EDITOR=nano && sudo -E visudo

  • After this what should I do ? as when trying to use sudo command I am getting above error. – Dcoder14 Oct 02 '19 at 05:02
  • Ahh sorry my mistake, I thought that it wasn't opening correctly. In the case of a corrupt sudoers file I believe that is best answered here: [link](https://askubuntu.com/questions/73864/how-to-modify-an-invalid-etc-sudoers-file) – Cameron Milton Oct 03 '19 at 01:59
