What solution to no valid sudoers found error ?



The error "no valid sudoers found" appears when you have modified the permissions of an important folders. You have added a user and know the system is saying that the "sudoers" are not valid anymore. This is a very serious issue.

Example of error made :

sudo chown -R username /etc


If you try the following :

sudo apt get update


You get :

no valid sudoers sources found, quitting


Solution : you can try to change the chmod of the sudoers

chmod 0440 /etc/sudoers


If it doesn't work, do it in the rescue mode.

You can try to modify the sudoers access :

nano /etc/sudoers.d/access


Modify it like that :

username ALL=(ALL) NOPASSWD: ALL


If it still doesn't work, you will have to start from scracth with your entire server.
