dkms.py crashed with ValueError in _apt_pkg(): package does not exist

[funit09]

Binary package hint: dkms

I'm using Ubuntu 11.04 beta 1
I wanted to install the vhba-dkms_1.2.1-0ubuntu6_all.deb package to further installation CDemu (It don't want to install from PPA)
So, Terminal displayed to me some error, and Apport sold me about this bag
Sorry for my bad English
