It is easy to miss steps when going through the ROS 2 installation tutorial.
If you run into errors in the next few steps, a good place to start is to go back and make sure you have installed ROS 2 correctly.
One that users commonly forget is to source the ROS 2 install itself.
Note to source the version of ROS you installed. ::

source /opt/ros/iron/setup.bash
source /opt/ros/jazzy/setup.bash

.. note:: Unlike ROS 1 setup scripts, in ROS 2 the setup scripts do not attempt to switch what version of ROS you are using. This means that if you have previously sourced a different version of ROS, including from within your ``.bashrc`` file, you will run into errors during the building step. To fix this change what is sourced in your ``.bashrc`` and start a new terminal.
