If you are like me, you probably installed Flash player from the repository, expecting it to work properly. Well, that just isn't the case. For instance, on YouTube or Hulu videos, I wasn't able to push the buttons without first right clicking, then left clicking twice. Weird, huh?

Here's how to get the Adobe Flash 64 bit Alpha for Linux working in Ubuntu 9.10 Karmic Koala.

First, close Firefox. Next, uninstall the following packages if you have them installed:

sudo apt-get remove flashplugin-installer flashplugin-nonfree nspluginwrapper

Download the 64 bit plugin from here: http://labs.adobe.com/downloads/flashplayer10.html

By default it downloads to /home/USER/Downloads, so the following steps will follow the default behaviour.

Two pieces of information regarding the following steps; replace USER with your username and the filename may change in the future, so keep that in mind when issuing the commands.

cd ~/Downloads
tar zxvf libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz
sudo cp libflashplayer.so /usr/lib/mozilla/plugins

Feel free to delete any leftover files in /home/USER/Downloads.

Start Firefox and you should now be able to play/navigate Flash videos without a problem. Leave, questions, comments or concerns below.
