How to get past the “flashplugin-nonfree is already installed” error on Ubuntu Gutsy Gibbon (7.10)

Google Query: flashplugin-nonfree is already installed

If you have built a new Ubuntu system recently like I have you may have run across this annoying error. If you go to a site like YouTube, Firefox prompts for you to install the flash plugin. I always choose the adobe plugin (flashplugin-nonfree). When I did this yesterday, I ran into a problem where the flash video would not load and Firefox asked me for the Flash plugin again. When I tried to re-install the plugin I got the above error.

The problem is that if you are not viewing the output of the “flashplugin-nonfree” installation, it looks like everything went well. However, if you look at the output you will see the following error:
md5sum mismatch install_flash_player_9_linux.tar.gz
The Flash plugin is NOT installed.

I finally found the solution to this problem at the Ubuntu Forums. There is a thread for this exact bug.

I downloaded the fix as a binary package for 32-bit and installed it.

You can also download the fix for 64-bit.

I hope this helps some of you with this frustrating error. Happy YouTube Watching

    For everyone’s inconvenience, the fixed package has been removed (because it had too many bugs). That’s handy, because now Flash is completely broken instead of only being partially broken.

    Flash is important enough to users, this is bad for Ubuntu’s reputation.
