Action version:
v4, v5

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
All versions.

Repro steps:
Use the action with any job with container: ubuntu:latest

Expected behavior:
Python is configured

Actual behavior:

 Version 3.12 was not found in the local cache
  Error: The version '3.12' with architecture 'x64' was not found for this operating system.

Workaround:
Instead of latest, use another tag such as 22.04.

Hello @ay0o
Thank you for creating this issue. We will investigate it and get back to you as soon as we have some feedback.

this is the SHA of the current latest: sha256:562456a05a0dbd62a671c1854868862a4687bf979a96d48ae8e766642cd911e8

Experienced the same error on our self-hosted runners using ubuntu:latest base image. Just as @ay0o suggested, using ubuntu:22.04 for latest 22.04 image fixed the issue. Seems that latest 24.04 image caused it https://hub.docker.com/layers/library/ubuntu/latest/images/sha256-28a2b328825ac02db5c29d9356bfba80ba6c4b6ebfcac5a91a4656fa3453775a?context=explore

[ay0o]

the content of /etc/lsb-release has not changed and uses the same format as expected by the code of the action in the _getOsVersion() function:

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu 24.04 LTS"

Also, just in case something odd happened, os.platform() returns linux as expected:

> os.platform()
'linux'

EDIT:

ah well... never mind, the issue is as simple as Ubuntu 24.04 is missing here https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json

So, in summary:

Ubuntu 24.04 was released a week ago and since then, marking the beginning of this issue because the tag latest replaced the previous version.

However, python-versions has not caught up with it and it's missing the release for 24.04.
