Hello Jay, or anyone else affected,

Accepted nova into ocata-proposed. The package will build now and be

-proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:ocata-proposed
  sudo apt-get update

Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-ocata-needed to verification-ocata-done. If it does
not fix the bug for you, please add a comment stating that, and change
the tag to verification-ocata-failed. In either case, details of your
testing will help us make a better decision.
