For some reason, when I try to run any programs (I am trying to run a rootkit hunter: rkhunter) as root on the command line with sudo like this:
Then I get this message:
You must be the root user to run this program
and then I get these lines:
sudo: error in /etc/sudo.conf, line 0 while loading plugin 'sudoers_policy' sudo: /usr/lib/sudo/sudoers.so must only be writable by owner sudo: fatal error, unable to load plugins
I try typing in just
sudo but that comes up with the same three errors as above. Also in
/etc/ sudo.conf does not exist.
I cannot run any other programs as root through sudo. It was also strange because I could run as root a day ago.
I would like it to work.
Just so you know, I am the only user of this computer, and the administrator, running Lubuntu 14.04.1.
