package samba 2:3.5.6~dfsg-4ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Binary package hint: samba

while doing 'apt-get update'

Side note, the automated questions that apport asks aren't useful in this kind of bug. It's asking if I'm running server or connecting to server and what clients are having difficulty connecting. This is an upgrade/package issue and not really a Samba configuration issue, AFAIK.
