self-hosted runner failing while trying to get version

[tabossert]

Describe the bug
Getting the following error when running
Version 3.x was not found in the local cache ##[error]Version 3.x with arch x64 not found The list of all available versions can be found here: https://raw.githubusercontent.com/actions/python-versions/master/versions-manifest.json

I have tried both v1 and v2 of setup-python and have tried setting a specific version or latest minor like above. I am running an amazon-linux runner and I am wondering if this will only work on Ubuntu. Could you provide some guidance. Thanks

Which version of the action are you using?

• v1
• [ X ] v2
• Some other tag (such as v2.0.1 or master)

Environment

• [ X ] self-hosted
• [ X ] Linux
• Windows
• Mac

If applicable, please specify if you're using a container
Not using containers

Python Versions
Please list all of the effected versions of Python (3.8.2, etc.)
3.7.7, 3.x

To Reproduce
Steps to reproduce the behavior:

1. Add setup action step to actions file
2. Set Actions file to use self-hosted runner
3. Run action

Run/Repo Url
Private repo

Screenshots

Additional context
The runner is using amazon-linux2 based ami

Seems it does work on Ubuntu with same config, might be good to add that this is Ubuntu only in readme for self-hosted

I also can't run those steps locally with act on mac

Officially we only support Python for the environments that are listed out here: https://github.com/actions/virtual-environments#available-environments

We compile Python from source for Ubuntu 1604, 1804 and Mac (10.15), the available versions for download are listed out here: https://github.com/actions/python-versions/blob/master/versions-manifest.json

If you have a local runner with something like Ubuntu 1904, then the platform_version will be different so nothing will be found in the manifest and the action will fail with the error you see. Same thing applies to Mac if you're using something other than 10.15.

The fact is it's not working on an amazon-linux runner is expected and we do not plan on supporting Python for configurations other than what we have in virtual-environments.

There are two things we can do here

• Update the README (we accept PRs 😃 )
  • Mention we only support the same platforms as those listed in virtual-environments
  • Explain why we only support those platforms
    - Maintenance, maintenance, maintenance
    - For Ubuntu and Mac, we compile from source so it is impossible to support all Linux distros and we have no plans to support more.
    - For Windows we download and use the MSI installers so those should work on all versions
• Even more logging and a better error message that says exactly why no version was found. It's very ambiguous right now.

Having the same issue with Ubuntu 18.04, I tried some other workarounds like setting the env RUNNER_TOOL_CACHE
RUNNER_TEMP to writable directories, but no change it still fails to get the python version.

Is for sure this is related to the Ubuntu version where the runner is ?

Hit this too. This seems like an issue in https://github.com/actions/toolkit. It reads version from /etc/lsb-release which seems to be deprecated in favour of /etc/os-release. That is, in most of the Linux distributions os-release is present, while lsb-release is not. The actions toolkit then can not figure version of the distro. Proposed fix in actions/toolkit#594

To give a bit of more context, its our own AMI based on Ubuntu 18.04

As you can see @konradpabjan we even find the proper version and we download it

Download from "https://github.com/actions/python-versions/releases/download/3.8.4-96744/python-3.8.4-linux-18.04-x64.tar.gz"

But then the error is hit
