Pip hangs after running any command (aside from --version, which is the only one that has worked for me)

[msmur]

Environment

• pip version: 20.0.2
• Python version: 3.8
• Operating system: Ubuntu 20.04 running on WSL2

Description

Running any pip command (except pip --version) seems to cause it to hang until keyboard interrupt

Expected behavior

The command typed is meant to be executed

How to Reproduce

Note: I linked pip3 to run with the alias pip since I uninstalled python 2.7

1. Get a fresh install of pip3 from 'sudo apt install python3-pip'
2. Try to run any command aside from --version
3. terminal hangs

Output
I am forced to keyboard interrupt

You likely want to disable pip's use of the keyring -- see #8719 for context.

Thanks, managed to get it fixed by

export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring

and disabling the xsrv display line I had.

1. I'm using pip and pipenv on a wsl2 environment (Ubuntu 20.04)
2. It was working just fine with vscode remote
3. Then I installed VcXsrv on Windows and got PyCharm to work on the WSL2 environment using this XServer and setting the DISPLAY variable on my .bashrc to be able to quickly launch PyCharm
4. Boom! Both pip and pipenv stopped working. Any command from them (with the exception of --version) hang until keyboard interrupt
5. Found this thread
6. Disabled the DISPLAY variable for the X server on my .bashrc
7. Boom! Fixed both pip and pipenv

I'm on windows so 'set' command worked for me instead of 'export'.

This was exactly it for me! I was trying to get tkinter to work in wsl and updated the DISPLAY variable. I never did get it working but forgot to remove my change. I just commented it out and pip is working again. Thanks a bunch!
