Hi Marco, Thank you for maintaining python related packages.
I found that the updated python38 (3.8.6-2, 3.8.7-1) and python36 (3.6.12-2) don't work with asyncio library. The "Hello World!" sample in python documentation fails. Using python38 (3.8.3-1) or python36 (3.6.10-1), it succeeds. This issue prevents ipython from starting up. Could you check if this issue is reproducible on your environment? ===== $ cat hello38.py # hello38.py (https://docs.python.org/3.8/library/asyncio.html) import asyncio async def main(): print('Hello ...') await asyncio.sleep(1) print('...
