Package 'interbotix_xsarm_descriptions' not found #59

What happened?

I have a Viper-X 300 (6dof). I followed the instructions to install ROS 2 Standard Software Setup(https://docs.trossenrobotics.com/interbotix_xsarms_docs/ros_interface/ros2/software_setup.html)

I have successfully installed the packages.

...
ros-galactic-desktop-full is already installed!
Apriltag ROS Wrapper already installed!
Interbotix Arm ROS packages already installed!
Environment variables already set!
Installation complete, took 29 seconds in total.

I restarted the laptop after the installation.

I'm able to detect the U2D2 interface:

ls /dev | grep ttyDXL
ttyDXL

But when i execute:

$ ros2 launch interbotix_xsarm_descriptions xsarm_description.launch.py robot_model:=vx300s use_joint_pub_gui:=true

It is throwing the following error:

`$ ros2 launch interbotix_xsarm_descriptions xsarm_description.launch.py robot_model:=vx300s use_joint_pub_gui:=true

I also noticed that the build for galactic has failed.

Did you source the workspace setup script before trying to run an Interbotix package? The search path seems to only be ['/opt/ros/galactic'].

The ROS 2 installation script does not configure your bash terminal to source the setup script for the Interbotix workspace. You need to source it each time you open a new terminal.

source ~/interbotix_ws/install/setup.bash

I also noticed that the build for galactic has failed.

This was just a CI issue that has now been fixed.

The issue is resolved.

Cause 1: I was not able to connect to the hostname raw.githubusercontent.com sometimes. The mentioned installation script(https://raw.githubusercontent.com/Interbotix/interbotix_ros_manipulators/main/interbotix_ros_xsarms/install/amd64/xsarm_amd64_install.sh) has many other resources hosted on that domain. Solution 1: I manually added the DNS lookup address in /etc/hosts filename

The installation script needs further checks. Even on partial installation the script prints a positive message stating that the Installation is successful.

Cause 2: After the installation, the port ttyDXL was not being shown. Solution 2: This was due to faulty microUSB cable; upon changing, the U2D2 interface was detected.

Closing the issue. Thanks @LSinterbotix
