I would suggest using ubuntu-minimal and centos-minimal elements for creating
images. This is what we do in openstack-infra today which means you'll build the
image directly from dpkg / rpm sources and not download existing images from
upstream.

This is the solve the issue which you are hitting if upstream images have been
removed / deleted / of failed to download.
