Python 3.6 x64 on Linux: Error: Version 3.6 with arch x64 not found

[SamuelMarks]

Description:
I've got a little project that I want to test on 3.6-3.11 on Windows, Linux, macOS. I've had no issues so far. Just upgraded to v4 of setup-python and now it doesn't work.

Action version:
v4

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
3.6

Repro steps:
https://github.com/offscale/cdd-python

Expected behavior:
It should work (it used to work)

Actual behavior:

Run actions/setup-python@v4
  with:
    python-version: [3](https://github.com/offscale/cdd-python/actions/runs/3494131617/jobs/5857054239#step:3:3).6
    architecture: x6[4](https://github.com/offscale/cdd-python/actions/runs/3494131617/jobs/5857054239#step:3:4)
    check-latest: false
    token: ***
    update-environment: true

Hello @SamuelMarks
We will investigate the issue and come back to you as soon as we have some news for you :)

Seems to be the same issue as #543 and the github runners updating from 20.04 to 22.04. There are no tarballs for 22.04 for any python 3.6.* versions. The fix may just be to hard-code the platform version to ubuntu-20.04 like @albertz did with rwth-i6/returnn@38ecab1

@SamuelMarks I think this is prematurely closed via a commit message. Can you reopen this? Hardcoding the Ubuntu version is not the best fix. There are many repos out there that would have to do the same thing, so it's best to be fixed in action.

[SamuelMarks]

@dvershinin Ah yes it was the commit message that did it. This issue should remain open. Depressing to see people link to this issue as a reason to drop support for Python 3.6 =(

…and great to see you guys working on a fix

We're seeing the same issue but with Python 3.9.5

Version 3.9.5 was not found in the local cache

I'm having the same problem for python 3.6 on a github action running on ubuntu-latest. The issue seems to simply be that there is no available build of Python 3.6 for ubuntu-22.04 (yet) from python-versions - as evident from the versions manifest.

I assume this is simply due to the fact that there has been no minor release of Python 3.6 after ubuntu 22.04 was released, so a build for that system was simply never triggered.

Now, if we could get someone to somehow cause a build for 3.6 for 22.04 to happen, that'd be great. I have, however, no idea at whom to address this request, as the python-versions repository has no possibility to open any issues. Maybe maintainers here can do something about that?

@levrik from the same version manifest linked above, it seems that Python 3.9 should work from 3.9.12 on but no earlier.

EDIT: just saw that ReeceASharp had already essentially pointed this out, so sorry for the spam. In that case however, I'd like to ask for an update on when to expect a fix ?
