sudo: no valid sudoers sources found, quitting

jojanmpaul · 02-25-2015, 05:46 AM

Hello,

I am getting the follwoing error for Red Hat Enterprise Linux Server release 6.6

sudo su -
sudo: >>> /etc/sudoers: syntax error near line 118 <<<
sudo: parse error in /etc/sudoers near line 118
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin

cd /etc/sudoers.d/
-bash: cd: /etc/sudoers.d/: Permission denied

Could you help me to figure it out. As a root user am able to access but as normal user it is not allowing to sudo su - command.

vi /etc/sudoers.d/access
username ALL=(ALL) NOPASSWD: ALL

Please let me know if any additional formation required.

This is why you should use visudo to edit /etc/sudoers -- it will warn you about syntax errors when you try to write the file. The error message is pretty obvious -- there's a syntax error around line 118 of your /etc/sudoers. You need to fix it before sudoers can run again. If you can't find the error, you can post that section of the config file. Since you're running RHEL, you're also assumedly paying for Red Hat support and you can also ask them to help you.

Hi all,

I have got solution for the same,

vi /etc/sudoers.d/access
username ALL=(ALL) NOPASSWD: ALL

there was one username in capital letter, I removed and issue got resolved.

Try with your user first. If it does not work try with others or root with command below
/usr/local/bin/sudo su -
Give the password.

You can use the below command again. The old user having wrong info will be updated with below.

echo 'YOUR_USERNAME ALL=(ALL) ALL' >> /etc/sudoers
