Expected behaviour

Run / Start Debugging, it works , as it worked before some unknown update for past 6 months.
Why is now ms-python touching locales?

Actual behaviour

File "/home/vscode/.vscode-server/extensions/ms-python.python-2020.3.69010/pythonFiles/lib/python/debugpy/no_wheels/debugpy/launcher/main.py", line 78, in

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

just try to debug python code inside any ubuntu 18.04lts container (i've used nvidia/cuda:10.2-cudnn7-devel-ubuntu18.04)

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

XXX

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)

Same behaviour, Python extension version 2020.3.69010, VS Online default environment.

[riazjahangir]

Experiencing the same behavior on MacOS 10.15.3 using Python extension 2020.3.69010, and even after downgrading to 2020.2.64397, running Python 3.8.0.

But this was working for me on Friday (3 days ago).

Dupe of microsoft/debugpy#87. We have the fix already, and it'll be in the next release.
