Initial Linux Setup Trouble

I’m using Linux on a Raspberry Pi 3 Model B (Raspbian Jessi), have downloaded the appropriate SDK from the “Develop” tab on the website, and ran through the “Updated Readme.txt” file that comes in the “2-Linux” folder download. The goal of the file is to run the “SimpleViewer” sample, but unfortunately after going through the steps in terminal, nothing happens. I run into trouble with checking the udev version because I can’t find the referenced directories anywhere. Any help would be fantastic!

What’s the vertion of your ROS, and do you Install astra_Ros packages ?!

I got it to work, thank you though!
