Dear Maintainer,

When I try to start  jupyter-qtconsole
I get the following exception
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 567, in
_build_master

    needed = self.resolve(parse_requirements(requirements))

pkg_resources.VersionConflict: (qtconsole 4.7.6 (/usr/lib/python3/dist-
packages), Requirement.parse('qtconsole==5.0.2'))

During handling of the above exception, another exception occurred:

This combination does not add up, and indeed I cannot reproduce this
when install jupyter-qtconsole from Debian testing. Please let us
know more about your local setup.

So then the package should have required specific version is debian/control
