[ros-users] [Discourse.ros.org] [General] RFC addressing side-by-side install of catkin_pkg for Python 2 and 3

[Dirk Thomas]

While there are Python 2 and Python 3 Debian packages if `catkin_pkg` they are not side-by-side installable which has been a long standing issue. If you have every tried to use e.g. `python3-ros-buildfarm` you have noticed that it basically collides with the core ROS Debian packages like `ros-<distro>-catkin`.

We will finally tackle this issue and have considered a couple of different approaches. Please see the [ticket](https://github.com/ros-infrastructure/catkin_pkg/issues/125#issuecomment-276210536) for more details about the requirements, rational, and approaches. Any feedback is highly welcome. Please comment on the ticket directly.

Cheers,
- Dirk
