A bug report

What is the current behavior?

On Ubuntu 18.04, after a

$ python3 -m pip install cherrypy

a

$ python3 -c "import cherrypy"

results in:

$ python3 my_mini_cherrypy.py
Traceback (most recent call last):
  File "my_mini_cherrypy.py", line 1, in <module>
    import cherrypy
  File "/home/sander/.local/lib/python3.6/site-packages/cherrypy/__init__.py", line 66, in <module>
    from ._cperror import (
  File "/home/sander/.local/lib/python3.6/site-packages/cherrypy/_cperror.py", line 135, in <module>
    from cherrypy.lib import httputil as _httputil
  File "/home/sander/.local/lib/python3.6/site-packages/cherrypy/lib/httputil.py", line 20, in <module>
    import jaraco.collections
ModuleNotFoundError: No module named 'jaraco.collections'

After pip uninstall, the import of (Ubuntu provided) cherrypy works:

$ python3 -c "import cherrypy; print(cherrypy.__version__)"
8.9.1

So a pip / pypi /packaing problem?

See above.

What is the expected behavior?
