I have lubuntu installed with persistance on a large usb flash drive, and somehow, My
/etc/sudoers file has file permissions 0664, when ever I try to use sudo, it says :
sudo: /etc/sudoers is mode 0644, should be 0440
sudo: no valid sudoers sources found, quitting
when I try
chmod 0440 /etc/sudoers it says:
chmod: changing permissions of `/etc/sudoers': Operation not permitted
sudo chmod 0440 /etc/sudoers causes the first message. Am I using chmod incorrectly? How can I fix this? If you need to know, it is lubuntu 10.10, isntalled with unetbootin.
EDIT: I know how to fix it with recovery mode, i just need to know how to get into recovery mode in a live cd, is it possible?
