I am having problems fixing the adobe-flashplugin package and because it's broken, upgrades to my system (testing) won't go ahead.

I foolishly tried to install the flash package from Adobe and now for some aptitude and dpkg can't fix/reinstall or purge it.

I have tried aptitude install -f......tried to use dpkg to remove or purge it. Most of the error messages say adobe-flashplayer has to be reinstalled, but can't find an archive file.
Is there a way around this, perhaps manually removing files, and the record
of it's installation..or can it be done some other way?
