I ran into this after changing the hostname of a Hardy machine (dist-upgraded yesterday) with KNetworkManager. The /etc/hosts file did not contain the new hostname after this and because of this sudo refused working from then on. One needs to boot into recovery mode or with a live CD to fix this problem by correcting /etc/hosts.
