Hi @kotran88 The packages on the distribution_linux.md instruction page are not designed for Arm-based devices such as Nvidia Jetson. Intel provide dedicated package installation instructions for Jetson at the link below.

what is weird is that I try to remove libgtk-3-dev with command

sudo apt-get remove --purge libgtk-3-dev

@MartyG-RealSense
wow so difficult to get realsense view...
I did try install libgtk-3-dev but this time cause different error

The following packages have unmet dependencies:
 libgtk-3-dev : Depends: libatk-bridge2.0-dev but it is not going to be installed
                Depends: libepoxy-dev (>= 1.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

should I go over every step installing unmet one?

I go over sources.list
and at the last,

deb https://librealsense.intel.com/Debian/apt-repo focal main
# deb-src https://librealsense.intel.com/Debian/apt-repo focal main

is it normal?
someone says I should add below to install libgtk-3-dev...
deb http://archive.ubuntu.com/ubuntu focal-updates main
