Thanks for that help. After adding -T, I got the full stack trace:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/sphinx/cmd/build.py", line 272, in build_main
    app = Sphinx(args.sourcedir, args.confdir, args.outputdir,
  File "/usr/lib/python3/dist-packages/sphinx/application.py", line 272, in __init__                                                                                                                                                  
    self._init_builder()
  File "/usr/lib/python3/dist-packages/sphinx/application.py", line 328, in _init_builder
    self.events.emit('builder-inited')
  File "/usr/lib/python3/dist-packages/sphinx/events.py", line 99, in emit
    results.append(callback(self.app, *args))
  File "/usr/lib/python3/dist-packages/sphinx/ext/intersphinx.py", line 233, in load_mappings
    with concurrent.futures.ThreadPoolExecutor() as pool: 
AttributeError: __enter__

It looks like a bug in sphinx, because the full stack trace consists
entirely of code from sphinx itself. I get the same error message when
disabling all extensions from salt (shipped in docs/_ext/).
