The "official" word on what dpkg should be doing regarding when and
how each of the {Pre,Post}{Inst,Rm} scripts is explained here:

Perhaps you want this as a PreRm not PostRm, so that it happens before
the old package gets rm'ed?

If you only want to do something if it's being fully removed, you need to do: if [ "$1" != "upgrade" ]; then # do stuff fi -- Benjamin Reed a.k.a.
