I am have just followed the installation procedure for ROS2 Foxy.

sudo apt install ros-foxy-desktop

This gives the following error:

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ros-foxy-desktop : Depends: ros-foxy-pcl-conversions but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I have rerun all the commands but it still does not work. I am not sure how to debug this but in the mean time I'll build from source.

Which OS?

Did you clean up the broken packages? Try sudo apt remove ros-foxy-desktop, and search for "Unable to correct problems, you have held broken packages" for advice on getting back to a good state.

The instructions at should work well.
