I don't think su is how you obtain root permissions on K/Ubuntu, I believe you use sudo as:-

sudo -i

When you use SU you are switching the acount to root. Root doesn't normally get used as to do so could cause security issues.
If you want to run a command use:

sudo
followed by the command.
What are you trying to do?

if you want shell access as root
then you have to do
sudo -s

su will not work
