I attempted to add myself to the sudoers file a couple of days ago. I didn't want to have to login into root to do anything so I went into the file and inserted my name under root. Now I cannot use the sudo command even when I'm logged into root. Does anyone know how to resolve this issue?

  • I'm using fedora server. I get this message: >>>/etc/sudoers: syntax error near line 99 <<< sudo: parse error in /etc/sudoers near line 99 sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin.

First 

su root

Use

EDITOR=nano visudo

To fix the file yourself. Or

rm /etc/sudoers

On Debian:

apt-get --reinstall install sudo

On Fedora:

yum reinstall sudo

Then do things the right way:

usermod -aG sudo,wheel [user]

Then

exit
sudo whoami

  • I got this error when I typed in the line after the rm command. bash: apt-get: command not found.
