How to skip pip upgrade?

[retzero]

Description:
I'm running self-hosted runner w/o internet connection.
Unfortunately the setup-python action perform pip upgrade and eventually failed due to network unreachable.
Q1) Is it possible to skip pip upgrade step?
Q2) How can I configure our internal private repository instead of pypi.org?

Hello @retzero,
Thank you for reporting this issue. We will investigate it and get back to you as soon as we have some feedback.

Hi @retzero, Thank you for reporting this issue. Based on the logs you provided, it seems the self-hosted runner's lack of internet access is causing the pip upgrade step to fail, as it cannot reach the PyPI servers.
Skipping pip upgrade step:
Currently, the setup-python action performs a pip upgrade by default. Unfortunately, as of now, there isn't a built-in option in the action to skip the automatic pip upgrade step.
Configuring an internal private repository:
To use an internal private repository, you can configure pip to use your repository by creating a pip.conf file. Here's how you can set it up:

- name: Override PIP Configuration
  run: |
    mkdir -p ~/.pip
    echo "[global]" > ~/.pip/pip.conf
    echo "index-url = https://<your-private-repo-url>/simple" >> ~/.pip/pip.conf

Replace with the URL of your private repository. Make sure your private repository is accessible from the self-hosted runner and contains all the required packages.
For additional context and configuration options, you can refer to the pip configuration documentation.
Additionally, we noticed you’re using version 3 of the setup-python action. We recommend upgrading to the latest version to benefit from performance improvements, better caching, and updated features. This might also help avoid similar issues in the future.
