I installed python3-magic-wormhole from the main OSS repo.
When running it with "wormhole", it says

Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 583,
in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 900,
in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 791,
in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (Twisted 19.10.0
(/usr/lib64/python3.8/site-packages), Requirement.parse('twisted>=20.3.0'),
{'autobahn'})

During handling of the above exception, another exception occurred:

It seems that the system-provided Twisted package (python3-Twisted) is too old
for wormhole.
