Rereading this, I meant to ask -- what's the relationship of this to the cache fix?

libreadline-dev and dkms come from libdevel, which seems to have mismatching hashes from what actually gets downloaded from the Ubuntu repos.

If you select these packages for install during preseed there is a hash mismatch and install bails.

However if you move them to post-install, as long as they execute before the vmtools provisioner runs, we are ok. So during the update script, I clear the inaccurate cache and refresh, then pull the requisite packages iff we are on this version of Ubuntu.
