$ ROSDISTRO is rolling, although ROS2 Galactic is installed

Question

I have recently installed ROS2 Galactic from source with instructions from the tutorials (https://docs.ros.org/en/galactic/Installation/Ubuntu-Development-Setup.html)

When I open a new terminal, and run echo $ROS_DISTRO, the variable is empty as expected.

I source galactic's setup file, source ~/ros2_galactic/install/setup.bash, then run echo $ROS_DISTRO.

rolling is printed out in the terminal, whereas it should be galactic, why could this be happening?

Answer 1

Could be because the version of the ros2.repos file those instructions have you download points to master, which makes you download the rolling branch of ros_environment.

Not sure why the documentation tells you to do that.

The Foxy instructions download the foxy version of ros2.repos.

I'd suggest opening an issue on the ros2/ros2_documentation issue tracker. You might even already fix it and submit a PR.

@ijnek: I guess this did not solve the problem after all?
