Make your browser lie to apple.com that you’re using a Windows machine. I made my Chrome to use the UserAgent string of Firefox on Windows. The video player loaded. Ubuntu seems to have a QuickTime plugin installed, so the video just played.
To change UserAgent of Chrome (i.e. to make Chrome pretend it’s Firefox running on Windows), open Menu > Tools > Developer Tools. Click on the Gear icon at the bottom-right corner and select UserAgent checkbox.
