This page is specific to Ubuntu versions 8.04

This page is dedicated to getting the Adobe Flash Mozilla-based browser plugin going, with sound, under Ubuntu LTSP (i386 only).

For Flash installations under AMD64-based Ubuntu, see this.

Installing Flash plugin automatically

It seems the Hardy repositories have gained the latest Flash 9 version. Simple to install, just:

sudo apt-get install flashplugin-nonfree
  • i386 Servers ONLY: Install the 'libflashsupport' package to allow sound to flow correctly over LTSP/PulseAudio:

sudo apt-get install libflashsupport

That should be all you need! (Re)Start Firefox on a thin-client for it to recognize the new plugin. You can verify the plugin is installed by navigating to about:plugins in the Firefox address bar and searching for "Shockwave Flash". Navigate to a random flash-enabled site to verify sound is working as well.

2008/10/17: NOTE ON FLASH 10: One of my sites, a school computer lab with 35 clients, experienced major CPU utilization with the newly released Flash 10 plugin (Ubuntu 8.04 .deb from Adobe's site). I would not recommend for anyone to use it yet in a production environment, but definitely try it and report back if you would like to test it. See Adobe thread here:

Alternate: Installing Flash manually

Do not follow these instructions unless you want to install Flash manually, and haven't already followed the automatic flash installation instructions above

  • Download the latest stable Adobe flash plugin ( version currently at "Shockwave Flash 9.0 r124" as of 2008/10/13 - download latest Linux .tar.gz at

  • Open a terminal and untar the flash archive:

tar zxvf install_flash_player_9_linux.tar.gz
  • Copy the plugin file to the correct location, so Firefox finds it:
