flash plugin failed to upgrade from amd64 alt CD

[matt]

Binary package hint: flashplugin-nonfree

On upgrading 9.04 to 9.10 using the amd64 alt CD the upgrade fails citing need for a dependancy that cannot be installed, this also stops access to the desktop on reboot, but using the "fix packages" recovery from the grub recovery selection fixes all issues
