For all of our currently-supported Ubuntu releases, the key is python-wxgtk3.0. So I think we should just replace this whole block with:

ubuntu: [python-wxgtk3.0]

Which has the added benefit of making us forwards-compatible.

@clalancette thanks! chaned to keep both backward/forward compatible

python-wxgtk3.0

Note that this Debian package depends on Python 2. It shouldn't be used in a package released into Noetic and Foxy because they are both targeting Python 3.

@sloretz not sure if I understand you comment correctly, python-wxgtk3. means gtk3.0 on python2. For python3 they have python3-wxgtk4.0

Yup. Since it depends on Python 2, this rosdep key shouldn't be used by any ROS packages in ROS Noetic or ROS Foxy. If the plan was to release a ROS package into Noetic or Foxy that currently depends on the rosdep key wxpython in Melodic or earlier, it should be updated to not use the wxpython rosdep key, but instead use a (to be created) python3-wxgtk4.0 rosdep key.

@clalancette has requested a simplification which is only possible by dropping distributions which are no longer supported. I'm in general in favor of that but also fine honoring specific requests from contributors to maintain current levels of support in our rosdep db.

Which is to say, I don't think we should add new keys, or restore dropped keys for older distributions on request since we can instead push individuals who need those to custom rosdep sources. But I don't see a problem with delaying the reduction of support based on contributor feedback.

That logic works for me. I'll re-review here.
