Comment 23 for bug 326609

Ok I have had this issue, I tried both sudo apt-get remove --purge flashplugin-nonfree and without the --purge option, and then re-installed didn't work, tried purging again deleted the .deb file from /var/cache/apt/archive folder, and then tried sudo apt-get install flashplugin-nonfree. That did not work at all.

I was finally able to solve the problem by downloading the adobe flash plugin (tar.gz) and copying the (.so) plugin to the /usr/lib/firefox-3.0.8/plugin folder.

the flashplugin-nonfree deb installer does not give any errors, apt does not give any errors.....
