# This script is to install librealsense.
# Update the system
sudo apt-get update
sudo apt-get upgrade

# 1. install Realsense SDK(supports Ubuntu LTS kernels 4.4, 4.8, 4.10, 4.13, 4.15, 4.18* 5.0* and 5.3*)
#Register the server’s public key :
sudo apt-key adv --keyserver keys.gnupg.net --recv-key C8B3A55A6F3EFCDE || sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key C8B3A55A6F3EFCDE

# Add the server to the list of repositories :
sudo add-apt-repository "deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo bionic main" -u
# When upgrading, remove the old records:

sudo rm -f /etc/apt/sources.list.d/realsense-public.list.
sudo apt-get update.

# In order to run demos install:
sudo apt-get install librealsense2-dkms
sudo apt-get install librealsense2-utils
# The above two lines will deploy librealsense2 udev rules, build and activate kernel modules, runtime library and executable demos and tools.

# Reconnect the Intel RealSense depth camera and run: realsense-viewer to verify the installation.

# Developers shall install additional packages:
sudo apt-get install librealsense2-dev
sudo apt-get install librealsense2-dbg
# With dev package installed, you can compile an application with librealsense using g++ -std=c++11 filename.cpp -lrealsense2 or an IDE of your choice.

# Verify that the kernel is updated :
# modinfo uvcvideo | grep "version:"should include realsense string
