cannot install latest packages on ubuntu (ciao-down)

This is a mirror of https://github.com/clearcontainers/runtime/issues/540 , we need to track it due it's a packaging issue.

cc-runtime fails to install, sighting that I have held broken packages. Details:

$> sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/clearcontainers:/clear-containers-3/xUbuntu_$(lsb_release -rs)/ /' >> /etc/apt/sources.list.d/clear-containers.list"
$> curl -fsSL http://download.opensuse.org/repositories/home:/clearcontainers:/clear-containers-3/xUbuntu_$(lsb_release -rs)/Release.key | sudo apt-key add -
$> sudo -E apt-get update
$> sudo -E apt-get install -y cc-runtime cc-proxy cc-shim
