Pip install block waiting forever for a keyring to unlock

Environment

• pip version: 20.0.2
• Python version: 3.7.6
• OS: Fedora

jaraco/keyring: v20.0.1 (automatically installed as PIP dependency)

Description

Pip block during install, waiting for a keyring to unlock (at least that’s my understanding)

Expected behavior

Pip install should proceed. I’m also confused about why pypi try to use any keyring to access pypi.org (See in the verbose output Getting credentials from keyring for https://pypi.org/simple).

How to Reproduce

pip install -vvv --no-deps --no-cache-dir -U importlib-metadata==1.1.3

Workaround Disable the keyring

PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring
pip install -vvv --no-deps --no-cache-dir -U importlib-metadata==1.1.3

Any solution to this? I have the same issue after a reboot on Ubuntu 18.04

Not a solution, but I as a workaround have added the following to my ~/.bashrc

# 1-May-2020: Fix for Keyring error with pip. Hopefully new pip will fix it
# soon https://github.com/pypa/pip/issues/7883
export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring

I had the problem on WSL2 that DISPLAY was set, but there was no X server running. This caused pip to hang on the keyring. The fix for me was simply:

unset DISPLAY
