Comment 1 for bug 586144

I have been trying to make the flash plugin work with Firefox. I have tried installing and uninstalling both the flashplugin-installer package, as well as the flashplugin-nonfree. Now, no matter what I try, I get the error noted here. Very frustrating. I believe the nonfree package is removed, but now I'm noticing this error is causing problems with installing other packages as well. Solutions?
