I had the need for Silicon Dust's HD Homerun configuration app on my Ubuntu Linux box. Silicon Dust makes it readily available but it's only as source from their site. I was feeling pretty nice and compiled it up for anyone else who needs the app. Basically it allows you to upload new firmware, scan channels and open them in VLC. It's pretty bare bones but does work.
After installing you'll need to start it from a terminal. There is no desktop shortcut for the app. So pop open a terminal and enter hdhomerun_config_gui. If it starts up then great, if not make sure you have the gtk+1.2 libraries installed.
If you're searching for HDHomerun Prime configuration software for Linux this might help. If you're looking for a way around the QAM channel encryption this will NOT help. I know, it's a bummer.
