Installation on Foxy with sudo apt #455

Closed floriankittelmann closed 2 years ago

Please complete the following information:

Describe the bug The packages are not available to run. ros2 pkg list | grep velodyne doesnt return anything. Do I need to build from source to run the velodyne node for ROS2 Foxy?

To Reproduce Steps to reproduce the behavior:

  1. sudo apt install ros-foxy-velodyne*
  2. ros2 pkg list | grep velodyne
  3. ros2 launch velodyne_pointcloud 32e_points.launch

Expected behavior ros2 launch velodyne_pointcloud 32e_points.launch should be possible but returns that package not found

florian@ubuntu~$ ros2 launch velodyne_pointcloud 32e_points.launch
Package 'velodyne_pointcloud' not found: "package 'velodyne_pointcloud' not found, searching: ['/home/florian/ros2_foxy/ros2-linux']"

@floriankittelmann It looks like you might not be sourcing your Foxy install folder first. You need to make sure that you run source /opt/ros/foxy/setup.bash before attempting to use a ros2 command. If this is the only version of ROS that you use, I recommend just adding source /opt/ros/foxy/setup.bash to the end of your ~/.bashrc file. Please let me know if this resolves your issue.

@JWhitleyWork Thank you for the hint! I was assuming that . ~/ros2_foxy/ros2-linux/setup.bash is enough to source the Foxy installation. But it seems source /opt/ros/foxy/setup.bash is also necessary. Unfortunately it was not described in the installation guide of Foxy https://docs.ros.org/en/foxy/Installation/Ubuntu-Install-Binary.html
