mitaka release need the nova-novncproxy package (http://docs.openstack.org/mitaka/install-guide-ubuntu/nova-controller-install.html)

  apt-get install nova-api nova-cert nova-conductor \
  nova-consoleauth nova-novncproxy nova-scheduler \
  python-novaclient

But I don't find the nova-novncproxy package in the mos9.0 repository
(http://mirror.seed-cz1.fuel-infra.org/mos-repos/ubuntu/9.0/pool/main/n/nova/)

Required package is only in ubuntu repositories, but that package is required specific version of nova-common, but nova-common has already been installed from the mos9.0 repository.

I've deployed env based on ubuntu+uca, so it have some bugs and cannot be deployed.
When I've redeployed env based on ubuntu - the env has been successfully deployed.
