+ /usr/bin/python3 setup.py build_sphinx -b man --build-dir build/sphinx
running build_sphinx
Running Sphinx v4.3.2

Exception occurred:
  File "/home/tkloczko/rpmbuild/BUILD/invocations-2.3.0/invocations/autodoc.py", line 90, in setup
    autodoc.add_documenter(TaskDocumenter)
AttributeError: module 'sphinx.ext.autodoc' has no attribute 'add_documenter'
