I'm trying to run ros2 iron irwini on Ubuntu 22.04.1 by using the ros2 documentation guide for ubuntu. I source the setup file like this: . ~/ros2_iron/install/local_setup.bash and then run a test program ros2 run demo_nodes_cpp talker. I keep getting ros2: command not found as a result. I have tried reinstalling ros2, and change local_setup.bash to local_setup.sh and local_setup.zsh but to no avail. Does anyone know what else I can try or what I'm doing wrong here? Thank you.
