Thanks for reporting this bug. This appears to be due to the following block in the ubuntu template:
# Finally update the lists and install upstart using the host architecture chroot $rootfs apt-get update chroot $rootfs apt-get install --force-yes -y --no-install-recommends upstart:${hostarch} mountall:${hostarch} iproute:${hostarch} isc-dhcp-client:${hostarch}
It looks as though this should be iproute2:${hostarch}, but I"m not sure which releases this is true for.
