Windows Version

Microsoft Windows [Version 10.0.22631.4602]

WSL Version

2.3.26.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.167.4-1

Distro Version

24.04

Other Software

Other Software:
pip 24.0 from /usr/lib/python3/dist-packages/pip (python 3.12)
Python 3.12.3

Repro Steps

I am using WSL 2 with Ubuntu 22.04. I am unable to install Python packages using pip. The error indicates a failure to establish an HTTPS connection to files.pythonhosted.org. The error persists even though I can ping pypi.python.org successfully. Below are the steps to reproduce the issue:

1. Create a virtual environment: python -m venv venv
2. Activate the environment: source venv/bin/activate
3. Attempt to install Django: pip install django

Error logs:

• Retry(total=4, connect=None, read=None, redirect=None, status=None)...
• Failed to establish a new connection: [Errno -2] Name or service not known

Steps I have tried to resolve the issue:

1. Updated pip to the latest version.
2. Configured /etc/resolv.conf to use Google DNS (8.8.8.8).
3. Ensured the firewall on Windows is not blocking the connection.

Despite these efforts, the problem persists.

Expected Behavior

I expected to successfully install Python packages using pip within my WSL environment. Specifically:

1. Run pip install django==4.2.15 in a virtual environment created with python -m venv.
2. The package and its dependencies should download and install without issues.
3. The installation process should establish a secure HTTPS connection to files.pythonhosted.org and download the required files.

Documentation reference: PyPI - Installing packages using pip

Actual Behavior

When attempting to install Python packages using pip in WSL, I encountered repeated connection failures. Below are the details:

1. Ran pip install django==4.2.15 in the activated virtual environment.
2. The installation failed with the following error:

ERROR: Could not install packages due to an OSError: HTTPSConnectionPool(host=‘files.pythonhosted.org’, port=443): Max retries exceeded with url: /packages/58/0b/8a4ab2c02982df4ed41e29f28f189459a7eba37899438e6bea7f39db793b/Django-5.1.4-py3-none-any.whl.metadata (Caused by NewConnectionError(’<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7f2756538950>: Failed to establish a new connection: [Errno -2] Name or service not known’
