[Bug 617005] Re: package man-db 2.5.7-2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

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.

Title:
  package man-db 2.5.7-2 failed to install/upgrade: subprocess installed
  post-installation script returned error exit status 2

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

Bug description:
  Binary package hint: man-db

  Just completed a fresh install of 10.04 and booted up. 
  Selected Update Manager and tried to install the latest security updates.
  Crash reported detected and then followed the on screen instructions to send you the file.

  Have since gone back into Update Manager to try and run remaining updates but failed again and also locked out Update Manager
  Am going to try a reboot and then UM again but wanted to send this bug report first.
