Flash wont install

[PurposeOfReason]

I've done a few installs a 64bit Gutsy and this has never happened to me. I went to install flash and I get this:
Download done.
md5sum mismatch install_flash_player_9_linux.tar.gz
The Flash plugin is NOT installed.

try the flashplugin-nonfree (multiverse)

I was getting exactly the same error last night. Funnily enough flashplugin-nonerror installed fine.

The error was being generated when it was checking the flash player download from adobe.

Have you tried again recently?

can try my fix on that thread... new flash player update and non updated nsplugin script are prob to blame. fix is there tho.

Well before I did anything I uninstalled the flash plugin this morning and tried again, worked fine. Go figure.
