Comment 1 for bug 177290

Originally, I was thinking this would be a problem with the change in md5 in the flash player stuff (Bug 173890). However, the script shows otherwise.

The new link would have to be: http://fpdownload.macromedia.com/get/flashplayer/installers/archive/fp7_archive.zip
Unfortunately, that is for all systems (including Windows and Mac), so it could mess up a part of the script

However, maybe you should try installing a newer flash player (Flash Player 9). Remove flashplugin-nonfree, and try using this package: http://archive.ubuntu.com/ubuntu/pool/multiverse/f/flashplugin-nonfree/flashplugin-nonfree_9.0.115.0ubuntu0.6.06_i386.deb

You could try enabling the backports repository, but that might give you Bug 173890. So try enabling the backports repository first; if it doesn't work, remove flashplugin-nonfree and then install the package.

I hope this is of help.
