now I'm really confused.
I added a versioned dependency on python-wxgtk3.0 >= 3.0.2.0+dfsg-7~ to
 the kicad package on Apr 8 2018 in preparation for
5.0.0_rc1+dfsg1+20180318-3.

The maintainers of the wxWidget related packages don't build a GTK2+
version of python-wxgtk3.0 package in Debian testing anymore. And this
will not change for the Buster release. So we need to deal with this.

This whole wx stuff and the relations between the various packages is
getting more and more worse in my eyes.
I don't what we or I can do to improve anything here. A possibility I
see is to remove the package dependency on python-wxgtk3.0 and adding a
Breaks instead because other binary packages can bring in a installation
of this package at any time. As we have already disabled the Python
scripting console (later) we don't really need python-wxgtk3.0 anymore
in KiCad and I should have removed this dependency already earlier?

Is there somewhere a explanation about the relationship of these
wxwidget packages we can use to add some more answers to the readme?
