Hello. Thanks to your video on youtube. I installed several things step by step. I completely installation with

  1. 'caffe Deep learning Framework - NVIDIA Jetson'
  2. 'Build Kernel and Modules - NVIDIA Jetson TX2' without any error. All screen same like yours. During the ros installation, every step was all good. I closed window when you close in youtube video. However, 'roscore' command was not working... It shows ' bash: roscore: command not found'.

I reboot and open new terminal and follow below one by one manually, again.

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 0xB01FA116
sudo apt-get update
sudo apt-get install ros-kinetic-ros-base -y
sudo apt-get install python-rosdep -y
sudo c_rehash /etc/ssl/certs
sudo rosdep init
rosdep update
echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc
source ~/.bashrc
sudo apt-get install python-rosinstall -y

and now it's working. sorry for bothering you.

Hi Sophie-shin, You probably just need to source the bash file, that's where everything gets setup for the ROS environment. You'll see that in lines like: $ source devel/setup.bash When you switch to the catkin-workspace
