I accidentally own /etc/ on user Ubuntu in aws ec2 I owned /etc/ and now this message comes up whenever I used sudo:

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

I have been finding answers here yesterday until now and I haven't found any solution that doesn't require stopping an instance.

(This is not the same as the 'another question' posted, why? because he can still run 'sudo' base on the comments I read, and this is a cloud server )

This is my /etc/sudoers file:

#
# 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.
#
Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

How do I fix this?

You will need to boot a live cd and run

sudo chown root:root -R /media/$USER/*/etc

You will need to open the folder in the file browser to mount the disk

Run: vim /etc/sudoers

You will find a line similar to: 

$ROOT: $ALL

Insert this line after:

$ <your_uid> : $ALL

But you need root permissions to do this.
