Downloaded Raspbian onto SD card using zip file from: https://www.raspberrypi.org/downloads/raspbian/.
Inserted SD card into Raspi and connected Raspi to monitor, keyboard, ethernet, power source, and a mouse.
Followed instructions under command line setup on: http://ardusub.com/raspi-setup/.
To open qgroundcontrol on personal laptop in Ubuntu assuming you have the App Image in your downloads folder type chmod +x ./Downloads/QGroundControl.AppImage and then ./Downloads/QGroundControl.AppImage
Decided we needed to start over and flash the ardusub raspbian image onto the raspi because it comes with qgroundcontrol. Followed instructions on http://ardusub.com/raspi-setup/ to complete this. Got to the end of the diskimage setup step. Still need to put card in raspi and test out. Also, hard to tell if there is currently anything on raspi. Will need to check.
Downloaded Ardusub Rasbian image from http://ardusub.com/raspi-setup/.
Used win32diskmanager to write the file onto the SD Card
