I've uploaded an ubuntu2 that adds %admin to the shipped sudoers file, which will workaround the loss of sudo when people hit "Y". This bug still needs more fixing, but it requires some thought on how to build an appropriate preinst script to handle the many cases of /etc/sudoers content, since it's traditionally been generated through a combination of the postinst-installed sudoers file and d-i/ubiquity adding the %admin line.
