Thank you for your interest in the Intel® Aero Ready to Fly Drone.
As Rohan kindly commented, please keep in mind the following statement from the official documentation while installing Ubuntu in your RTF drone:
Many developers may prefer prototyping with typical linux distributions like Ubuntu. Intel is not supporting nor shipping Ubuntu on Intel Aero, but the community may publish recipes on how to install Ubuntu manually. Ubuntu and other Linux distros may be installed on Intel Aero, but some functionality may or may not work, notably the cameras from the Computer Vision kit.
Have a nice day.
Can you please share your steps to install librealsense on ubuntu ? I had some trouble doing that on my laptop. I ended up just copying the so's from the drone over. I would appreciate if you can share your steps. I folowed the Wiki but no luck.
