I don't know of a way to rebuild a corrupt database. I suppose with a lot
of work you could query another box to find out what packages the files
you have left belong to and count that as your db, but I don't know of
anything that would do such a thing.

JLF has mentioned how to do this before. I believe these snippets from the
dpkg man page are appropriate:

       To make a local copy of the package selection states:
            dpkg --get-selections >myselections

       You  might  transfer  this  file  to another computer, and
       install it there with:
            dpkg --set-selections <myselections
       Note that this will not actually install  or  remove  any­
       thing,  but just set tghe selection state on the requested
       packages.  You will need some other application  to  actu­
       ally download and install the requested packages.

BTW, anyone know what a SELECTION STATE of deinstall means?
