I faced this issue when I want to use sudo command :

sudo: /etc/sudoers is owned by uid 1000, should be 0
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin

then I tried a solution from a similar question in order to change the owner back to the root: 

$ pkexec visudo

also I tried this one 

$ pkexec chown root:root /etc/sudoers /etc/sudoers.d -R

but I have faced another issue with these commands: 

Error getting authority: Error initializing authority: Could not connect: No such file or directory

So is there a solution to this issue?


Full shell issue snippets: 

ubuntu@LAPTOP-D4T16P7J:~$ sudo -i
sudo: /etc/sudoers is owned by uid 1000, should be 0
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
ubuntu@LAPTOP-D4T16P7J:~$ pkexec visudo
Error getting authority: Error initializing authority: Could not connect: No such file or directory
ubuntu@LAPTOP-D4T16P7J:~$ pkexec chown root:root /etc/sudoers /etc/sudoers.d -R
Error getting authority: Error initializing authority: Could not connect: No such file or directory


This is my /etc/sudoers file: 

ubuntu@LAPTOP-D4T16P7J:~$ cat /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.

The answer was as follow:

  • access root user by issuing this command in windows command line (CMD): 

    wsl -u root

  • change ownership of /etc/sudoers file to the root:

    chown root:root /etc/sudoers


Thanks to @Terrance for him help.

I've had similar issue.

using wsl -u root resulted in error.

Open cmd, run wsl -l to get distribution name.

In my case output was Ubuntu-18.04

run wsl -d Ubuntu-18.04 -u root

You should be using root now.

run chmod 440 /etc/sudoers
