Comment 12 for bug 184336

Thanks for your bugreport.

If update-manager in hardy (or any pre-release version of ubuntu) can not calculate the upgrade, that is not a bug per-se. It mostly means that the archive is in a state of flux and a upgrade can not be calculated without removing ubuntu-desktop (or a similar imortant package). I fixed the error message in update-managers bzr to make this more clear.
