Just for the record, because Henry Lin did contact me via email, the packages site does display correct information here, the Packages file for quantal contains the Recommends from dkms to linux-headers.
What distributions are you really using? Because your original install screenshot did show a virtual-guest-dkms version that isn't in quantal but raring? In quantal everything was correct, it's raring that you seem to be using and which is causing you the trouble. And indeed, dkms on quantal doesn't recommend linux-headers anymore. And when looking into the changelog of raring for dkms, one finds that linux-headers got removed with this rationale: dkms (2.2.0.3-1.1ubuntu2) raring; urgency=low * Don't Recommend any linux-headers packages, our installers all install headers matching your kernel anyway, and this dependency causes more problems than it solves (LP: #960770) -- Adam Conrad <adcon...@ubuntu.com> Wed, 31 Oct 2012 11:28:52 +0000 So you should look into that bugreport and speak with Adam (I subscribed him to this bug now).
