Following the instructions in section 2.2.2, the ROS-Comm install doesn't work. Going to returns the following error:


Request Method: GET

Exception Type: AttributeError at /rosinstall/generate/dry/raw/groovy/ros_comm
Exception Value: 'NoneType' object has no attribute 'get_stack_names'

Both the full-desktop and desktop seem to work fine (they return a list of packages to install).

It looks like you're trying to generate a rosinstall file for a wet stack with the dry toolchain. Can you try this instead?

Yes that returns a list of packages. @WilliamWoodall is leveraging the "install from source" instructions for linux. They want us to build a dry tool chain first it appears. I am just trying to let them know it is broken for ros_comm, but works for the other two.

Yes, this should not be used in the case of ros_comm. We are intending to replace ros_comm with an actual variant in the future. But the rosinstall generate could give a more meaningful response, like # No dry packages selected or something similar, which would result in an empty rosinstall.

I updated the installation instructions to reflect this.
