[Bug 565184] Re: package flashplugin-installer 10.0.45.2ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Tamas Rev]

i managed to remove flashplugin-nonfree with 2 dirty steps:
1. edit /var/lib/dpkg/info/flashplugin-nonfree.prerm (you might want to create a backup first)
  the new version should look like this:
    #!/bin/sh
    # prerm script for flashplugin-nonfree
    #
    # see: dh_installdeb(1)

    set -e

    exit 0

2. run dpkg --force-remove-reinstreq -r flashplugin-nonfree

In case dpkg complains for more scripts resulting in non-zero statuses,
edit the corresponding scripts too.

3. finally you might want to remove the flashplugin files yourself
