Comment 5 for bug 203419

Please correct me, if I'm wrong, but you appear to confuse "dpkg" with "apt-get".
dpkg is rather "low-level" and requires a .deb file to be installed, while you use "apt-get" with package names from repositories.

So, the following should work, but probably tell you that it's installed already:
  sudo apt-get install linux-ubuntu-modules-$(uname -r)

As said, please re-open the bug in case I'm missing your point.
Thank you.
