Rather than purging and re-installing, have you considered just updating? `sudo update-flashplugin-nonfree --install` This command works on debian based systems (as far as I know) and I typically prefer it in place of using apt, since your distribution's repos may not have the most current version (Debian Wheezy, for example).
