package flashplugin-installer 10.0.45.2ubuntu1 failed to install/upgrade: exit status 2 - update-alternatives: error: /var/lib/dpkg/alternatives/iceape-flashplugin corrupt: invalid status

Binary package hint: flashplugin-nonfree

When installing flashplugin-installer apt-get reports the error message reported below.
When this occurs I'm unable to remove or install the plugin.
I manually removed the package by using: gksu gedit /var/lib/dpkg/status and removing the package details and then attempted a re-install with the same problem.

If I look in firefox flash is loaded however the myth packages mentioned below appear to require this particular version.

Download done.
Flash Plugin installed.

That distro have reached EOL since a while; and such problem has been resolved long time ago.
