[Bug 1166129] Re: package man-db 2.6.1-2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

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.

  post-installation script returned error exit status 1

Status in “man-db” package in Ubuntu:
  Confirmed

Bug description:
  1. while executing "sudo apt-get install audacity" the first time I
  got a window with EULA for Microsoft terms/conditions, however the
  <ok> btton did not work - I killed the window.

  2. On re-running, I had to remove some locks using "sudo rm ..."

  3. Then running "sudo apt-get install audacity" I got following
  errors:

  installer' missing, assuming package has no files currently installed.
