all py3 programms throw same error after update

[Beavis]

Hi,

I am on Ubuntu and I upgraded my pip3 packages and that broke my system. Now every p3 program does this:

    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2976, in <module>
    @_call_aside
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2962, in _call_aside
    f(*args, **kwargs)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 3004, in _initialize_master_working_set
    dist.activate(replace=False)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2535, in activate
    declare_namespace(pkg)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2109, in declare_namespace
    _handle_ns(packageName, path_item)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2058, in _handle_ns
    _rebuild_mod_path(path, packageName, module)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2078, in _rebuild_mod_path
    orig_path.sort(key=position_in_sys_path)
AttributeError: '_NamespacePath' object has no attribute 'sort'

I cleaned up and reinstalled all python3 related packages, what to do next?

Thanks a lot.
