To install the Promethean Activboard Driver and ActivInspire Software On Ubuntu 12.04 or 13.04 follow the steps below:
Note: Please note that Promethean supports only 32 bit Ubuntu systems. I have not tested it for 64 bit systems.

sudo apt-get install libjpeg62

From the Ubuntu Software Center add the following repository in “Other Sources”:

deb http://activsoftware.co.uk/linux/repos/ubuntu precise oss non-oss

Back in a terminal run:

wget http://www.activsoftware.co.uk/linux/repos/Promethean.asc && sudo apt-key add Promethean.asc

then

sudo apt-get update
sudo apt-get install activinspire activtools activdriver

Now logout and login again and try running Activinspire.
