Stopped working after Ubuntu upgrade

[DarkAllMan]

Noobs here....
But after updating my ubuntu version, it all stopped working:
Traceback (most recent call last): File "./miio_server.py", line 9, in <module> from gevent import monkey File "././.env/lib/python3.6/site-packages/gevent/__init__.py", line 86, in <module> from gevent._hub_local import get_hub File "././.env/lib/python3.6/site-packages/gevent/_hub_local.py", line 101, in <module> import_c_accel(globals(), 'gevent.__hub_local') File "././.env/lib/python3.6/site-packages/gevent/_util.py", line 148, in import_c_accel mod = importlib.import_module(cname) File "/usr/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) ModuleNotFoundError: No module named 'gevent._gevent_c_hub_local'

Can anyone point me in the right direction? I see python 3.6 mentioned, but my current system has 3.8.5?
