rmw_implementation dependency on rmw_opensplice_cpp

I just upgraded to Dashing and ran into this issue when compiling control_msgs. As a workaround, I wanted to just uninstall the current openslice packages but there appears to be a required dependency chain that won't let it uninstall.

rclcpp -> rmw_implementation -> rmw_opensplice_cpp -> rosidl_typesupport_opensplice_cpp

I would not have expected rmw_implementation to depend on rmw_opensplice_cpp here (or rmw_fastrtps_cpp). Is this intended? Note, for example, that rosidl_typesupport_cpp only suggests rosidl_typesupport_opensplice_cpp, which is what I would expect.

(side note: "dashing" needs to be added to the ROS answers distribution tag list)

It looks like you're seeing this issue, and the fix is in the process of being released.

The opensplice packages can be temporarily removed using dpkg.

sudo dpkg --remove --force-depends ros-dashing-rmw-opensplice-cpp ros-dashing-rosidl-typesupport-opensplice-cpp ros-dashing-rosidl-typesupport-opensplice-c

Before you upgrade or install other packages you'll want to reinstall the opensplice packages that were force uninstalled using

sudo apt-get install --fix-broken

Thanks! Glad to hear everything is under control.
