Pre-release Testing

Many ROS packages are provided as pre-built binaries. Usually, you will get the released version of binaries when following Installation. There are also pre-released versions of binaries that are useful for testing before making an official release. This article describes several options if you would like to try out pre-released versions of ROS binaries.

Debian testing repository

For Debian-based operating systems, you can install binary packages from the ros-testing repository.

  1. Make sure you have a working ROS 2 installation from Debian packages (see Installation).

  2. Edit (with sudo) the file /etc/apt/sources.list.d/ros2-latest.list and change ros2 with ros2-testing. For example, on Ubuntu Focal the contents should look like the following:

    # deb http://packages.ros.org/ros2/ubuntu focal main
    deb http://packages.ros.org/ros2-testing/ubuntu focal main
    
  3. Update the apt index:

    sudo apt update
    
  4. You can now install individual packages from the testing repository, for example:

    sudo apt install ros-dashing-my-just-released-package
    
  5. Alternatively, you can move your entire ROS 2 installation to the testing repository:

    sudo apt dist-upgrade
    
  6. Once you are finished testing, you can switch back to the normal repository by changing back the contents of /etc/apt/sources.list.d/ros2-latest.list:

    deb http://packages.ros.org/ros2/ubuntu focal main
    # deb http://packages.ros.org/ros2-testing/ubuntu focal main
    

    and doing an update and upgrade:

    sudo apt update
    sudo apt dist-upgrade
