"'GLIBC_2.38' not found" when installing Python 3.10 on container derived from python:3.10-slim

[lpascal-ledger]

Hello there 👋 Thanks for the action, very useful! We've encountered a strange bug today:

Description:

We're using setup-python in a matrix to test our product on several Python versions.

The tests were running in a container derived from python:3.9-slim, where we previously installed all our tools. We were running tests with Python 3.8, 3.9, 3.10 and 3.11 and all was working fine.

Today we updated this image to python:3.10-slim, but now when we setup Python 3.10, python crashes when invoked.

Our tests also run with Python 3.11 setup which does not trigger this issue.

Action version:

actions/setup-python@v5

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

Repro steps:

I've tried and cornered the issue in the following workflow which triggers the bug:

name: Debug
on:
  workflow_dispatch:
  push:

jobs:
  not_working:
    runs-on: ubuntu-latest
    container:
      image: python:3.10-slim
    steps:
      - uses: actions/setup-python@v5
        with:
          python-version: "3.10"
      - run: python

An example of this failing workflow can be found here.

Expected behavior:

Python can be invoked without error.

Actual behavior:

When invoked, python crashes with the following errors:

python: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found (required by /__t/Python/3.10.16/x64/lib/libpython3.10.so.1.0)
python: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by /__t/Python/3.10.16/x64/lib/libpython3.10.so.1.0)
Error: Process completed with exit code 1.

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

We are getting something that looks alot like this, but this occurs when running with ubuntu-latest with a debian bookworm based image. When setting the machines to ubuntu-22.04 the issue is not present.

Hi @lpascal-ledger,

As the GLIBC library and other packages and tools have been removed from Ubuntu 24 due to maintenance and efforts to reduce the image size, we suggest using Ubuntu 22 or Ubuntu 20 runners to resolve this issue.

Please find the updated workflow and a screenshot for your reference:

name: Debug

on:
  workflow_dispatch:
  push:

jobs:
  not_working:
    runs-on: ubuntu-22.04
    container:
      image: python:3.10-slim
    steps:
      - uses: actions/setup-python@v5
        with:
          python-version: "3.10"
      - run: python

Thank you for your understanding. Please feel free to reach out if you have any further concerns or need additional clarification!
