Title:
  package man-db 2.5.9-4 failed to install/upgrade: subprocess installed
  post-installation script returned error exit status 1

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

Bug description:
  Binary package hint: man-db

  I was trying to install 'tuxguitar'. I got an error message when I
  tried to install it, was directed to a forum discussing how to fix
  this problem, which involved the following terminal commands; 'sudo
  apt-get remove', 'sudo apt-get update' and 'sudo apt-get upgrade'. The
  last command gave another error message:

  E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
  E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

  I looked up how to fix this, which involved going onto the 'System
  Monitor' and killing all processes which included 'aptget' and 'dpkg'.
  So I did this, retried the process, which seemed to work. Then it told
  me I have this problem, and I don't even know what this problem is.

  I hope I included relevant details here, I'm new to Ubuntu
