Comment 9 for bug 425974

looks like you did *not* follow Daniel's suggestion. He said you to:

1) completely remove (purge) flashplugin-installer
2) enable the Canonical partner repository
3) install the adobe-flashplugin package

What you did is:

1) purge flashplugin-installer
2) install flashplugin-installer again

You should do this with a 32-bit installation only anyway.
