Unable to execute actions/setup-python

[rgarrigue]

Hi there

Thanks for act. I've been using it successfully until now, but here's some issue running python related tests : it's unable to execute the setup-python action.

I tried with both my "old" act version from a couple of month ago and latest 0.2.8 from GitHub releases. With and without the matrix on python version. With actions/checkout@v1, v2 and master.

name: Tests
jobs:
  tests:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python: [3.7]
    steps:
      - uses: actions/checkout@v2
      - name: Setup Python
        uses: actions/setup-python@v2
        with:
          python-version: ${{ matrix.python }}

And here's the verbose log

act -v

I've hit the same issue, I've found that if you set a GITHUB_TOKEN env var, it doesn't give the bad credentials error, and proceeds, only to fail a bit later:

[svdgraaf]

I'm not sure, but I think it fails because I'm running it on osx, but the installation is running through the docker container on linux, and it's not understanding which version it should install. I think? :)

The manifest does contain the right version it should use: https://raw.githubusercontent.com/actions/python-versions/master/versions-manifest.json

For the records I'm running it under Ubuntu 19.10

[whettie]

So good.

[RaulBSantos]

Same here, and I'm using ElementaryOS under Ubuntu 18.04.4.

Some of you guys tried with another image? Just wondering if this may solve, cause I couldn't try with the alternative image, my disk space it's insufficient :(

[rgarrigue]

@RaulBSantos it does work running

act -P ubuntu-latest=nektos/act-environments-ubuntu:18.04

[Tests/tests]   ✅  Success - Setup Python
...

Since that's fine enought for me I'll add the -P option to my .actrc.

For other user willing to push the investigation, the setup-python author suggested following this guideline https://github.com/actions/setup-python#using-setup-python-with-a-self-hosted-runner. I gave it a quick shot without success.

[april]

Yep, I'm having the exact same problem here as well. On macOS, always gives me the the Version ... with arch x64 not found error, even if I specify something as specific as 3.8.3.

Setting the .actrc as specified above did fix things, however.

[grische]

I created a simple test file which re-creates the problem

name: pull_requests
on: [pull_request]

jobs:
  test_pr:
    runs-on: ubuntu-18.04
    steps:
      - name: Set up Python
        uses: actions/setup-python@v2
        with:
          python-version: "3.7"

It is fixed by adding the -P parameter like the following:

[pull_requests/test_pr]   ❓   ##[add-matcher]/actions/actions-setup-python@v2/.github/python.json
[pull_requests/test_pr]   ✅   Success - Set up Python

Here are the respective lines from the setup-python action: https://github.com/actions/setup-python/blob/807b74f98ca701f414ddaa8a4187e7cffa93cbbd/dist/index.js#L999-L1023

Here is my lsb-release file:

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.4 LTS"

$ uname -a
Linux DESKTOP-WINDOWS10 4.19.104-microsoft-standard #1 SMP Wed Feb 19 06:37:35 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

EDIT: Removed my previous invalid comment

[imbillow]

the problem still exists

[dskvr]

In order for this to work, one would write a docker file using nektos/act-environments-ubuntu:18.04 as a base image (FROM nektos/act-environments-ubuntu:18.04) that would need to include all caveats listed here.

Sounds like @rgarrigue tried something like this without success. Bummer.

Still having this problem as well, running Ubuntu 20.04.1 LTS, with 5.4.0-42-generic as my kernel (if that helps or matters at all).

[dustydecapod]

Still a frelling issue

[maxphillipsdev]

I just ran into this issue as well :(

[rickstaa]

I solved this by using the method explained by @grische.

[noliran]

Found the problem - @actions/tool-cache:lib/manifest.js uses _readLinuxVersionFile() to determine the version of the ubuntu distribution using the line DISTRIB_RELEASE=18.04 in /etc/lsb-release . This file doesn't exist in node:12.6-buster-slim, the default image act currently uses. I'm currently using this as workaround:

      - run: |
          # Hack to get setup-python to work on act
          if [ ! -f "/etc/lsb-release" ] ; then
            echo "DISTRIB_RELEASE=18.04" > /etc/lsb-release
          fi

Not really sure what's the right fix here - It doesn't make sense that @actions/setup-python treats Ubuntu's release version as platform_version and hands out Python versions based on it. That doesn't make sense..

[charlielito]

Same problem with Ubuntu20.04, @noliran solution solved it

[rickstaa]

@noliran his solution worked for me. I use it in the following way:

# Pull request ci config file
# Note: For local testing with https://github.com/nektos/act use the
# `sudo act -P ubuntu-18.04=nektos/act-environments-ubuntu:18.04` command.
name: MLC pull CI

on:
  # Trigger the workflow on a pull request,
  # but only for the master branch
  pull_request:
    branches:
      - master

jobs:
  build:
    name: runner / build
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2
      - name: local-fix
        run: |
          # Hack to get setup-python to work on act
          # (see https://github.com/nektos/act/issues/251)
          if [ ! -f "/etc/lsb-release" ] ; then
            echo "DISTRIB_RELEASE=18.04" > /etc/lsb-release
          fi
      - name: Set up Python
        uses: actions/setup-python@v2
        with:
          python-version: "3.8"

The PR fixing this issue still hasn't been merged.

[bashbang]

This has still been a problem for me on my OSX. I incorporated the "hack" that @noliran mentioned above and deleted the /Users/{myusername}/.cache/act/* and now works as expected.

      - run: |
          # Hack to get setup-python to work on act
          if [ ! -f "/etc/lsb-release" ] ; then

          fi

Still waiting on actions/toolkit#594

[catthehacker]

Hi all, if you will use medium or large image (https://github.com/nektos/act#runners) there shouldn't be any problem as those include lsb-release which will successfully provide OS version to setup-python. As this is external issue, I will close this.

[GatlenCulp]

It's 2024 and this is still an issue
