{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Linux inly supports Ubuntu","articleBody":"**Description:**\nactions@setup-python exclusively supports Ubuntu, despite claims of [Linux](https://github.com/actions/setup-python/blob/main/docs/advanced-usage.md#linux) support for self-hosted runners.\nFurthermore, in the [versions-manifest.json](https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json), the platform is _linux_, yet the platform version is 22.04, which happens to work for Ubuntu images only. It may be more relevant to [actions/python-versions](https://github.com/actions/python-versions), but issues cannot be created there.\nThe only pertinent information available [here](https://github.com/actions/setup-python/blob/main/docs/advanced-usage.md#using-setup-python-with-a-self-hosted-runner) states:\n\u003e Python distributions are only available for the same [environments](https://github.com/actions/runner-images#available-images) that GitHub Actions hosted environments are available for. If you are using an unsupported version of Ubuntu such as 19.04 or another Linux distribution such as Fedora, setup-python may not work.\n\nDespite this, the documentation continues to represent the platform as Linux, not specifically Ubuntu.\n\n**Action version:**\nAny version\n\n**Platform:**\n- [x] Linux ~Ubuntu~\n- [ ] macOS\n- [ ] Windows\n\n**Runner type:**\n- [ ] Hosted\n- [x] Self-hosted\n\n**Tools version:**\nAll Python versions\n\n**Repro steps:**  \nUtilize a self-hosted runner with any Linux distribution other than Ubuntu.\n\n**Expected behavior:**\nSupport should be extended to other Linux distributions, or the documentation and references (such as [this](https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json)) should explicitly specify that only Ubuntu is supported, not the entire Linux platform.\n\n**Actual behavior:**\nThe version '3.12.11' with architecture 'x64' was not found for this operating system.
