So I accidentally ran
chmod 775 /usr/lib/*
Yup, a fool.
So now I get this error whenever I try to do anything that uses sudo :
sudo: /usr/lib/sudoers.so must be only be writable by owner
One of the solution is logging in by root and changing the permission, but I can't do that because I don't know how.
What I've tried :
sudo -i (Uses Sudo)
su - and enter my password ('Operation Not Permitted')
booting into linux and trying to mount the DSM drives - couldn't mount it
I have the ADMIN account disabled due to security reasons.
I'm ready to face reset, but it takes too long to clean up.
Any ideas?
