Install Flash 9 on Ubuntu Hardy 64-bit

When I tried to install Adobe Flash for Firefox, the following error occured:

Your architecture, \’x86_64\’, is not supported by the Adobe Flash Player installer.

Googled a little bit ,and eventually solved the problem.

1. Get the Adobe flash :

wget http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_9_linux.tar.gz

2. Untar

tar -xvzf ./install_flash_player_9_linux.tar.gz

3. Copy the libflashplayer.so file to your mozilla plugins folder.

cp install_flash_player_9_linux/libflashplayer.so ~/Firefox/plugins

4. Now the magic bullet kindly provided by Gwenole Beauchesne.
sudo aptitude install nspluginwrapper

nspluginwrapper -i ~/Firefox/plugins/libflashplayer.so


Ok, problem solved
