To install the ADK you need:
Once you have installed the VM environment, perform all system updates and upgrades before running the Ubuntu 10.04 VM provided by Yahoo. After opening and running the provided VM, do not attempt to update or upgrade the VM environment again as this may change ADK dependencies. System updates for the provided VM have been disabled to prevent support issues with Ubuntu 10.04 configurations that have not been tested by Yahoo Connected TV.
If you are using VirtualBox see VirtualBox Instructions for more information.
