Thanks for your report.  The basic problem here is that man-db's trigger
uses debconf to decide whether to update the manual page database, but
debconf is not always reliably usable in triggers.  I finally figured
out a simple way to avoid this problem, which I'm tracking as bug
1372673.  If you are still affected by this locally (which I realise is
unlikely in the case of some of the older bugs of this type), then
running "sudo dpkg --configure -a && sudo apt-get -f install" in a
terminal should normally be enough to get the package management system
back to a sensible state.
