I have a similar error, here the exact error message:

Setting up policykit (0.7-2ubuntu4) ...
chown: cannot access `/var/run/PolicyKit': No such file or directory
dpkg: error processing policykit (--configure):
 subprocess post-installation script returned error exit status 1

DISTRIB_ID=Kubuntu
DISTRIB_RELEASE=8.04 beta KDE3
DISTRIB_CODENAME=hardy
DISTRIB_DESCRIPTION="Ubuntu hardy (development branch)"

sudo mkdir /var/run/PolicyKit

seems to fix the problem and let's the configuration of its dependencies succeed.

I can confirm:
creating the directory solves the problem.
I can now update my packages.

I hope they fix this before the final release of Hardy!
