packages.gitlab.com returns 404 for Amazon Linux 2023 (amzn/2023) repository config

Summary

The repository config URL for Amazon Linux 2023 returns 404, making it impossible to install gitlab-runner using the official script.rpm.sh on Amazon Linux 2023.

Environment

• OS: Amazon Linux 2023 (Amazon Linux 2023.10.20260120)
• /etc/os-release: ID=amzn, VERSION_ID=2023
• gitlab-runner version intended: 18.1.3

Steps to reproduce

curl -L "https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.rpm.sh" | sudo bash

Error

curl: (22) The requested URL returned error: 404
Repository config not available: https://packages.gitlab.com/install/repositories/runner/gitlab-runner/amzn/2023/config_file.repo
OS/distribution may not be supported or detection failed.

Root cause

The script.rpm.sh correctly detects os=amzn dist=2023 from /etc/os-release and builds the URL:

https://packages.gitlab.com/install/repositories/runner/gitlab-runner/amzn/2023/config_file.repo

This URL returns 404. The same happens for amzn/2 as well.

Workaround

Forcing el/8 detection works:

curl -L "https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.rpm.sh" | sudo os=el dist=8 bash
sudo dnf install gitlab-runner-18.1.3 -y

Request

Please restore the amzn/2023 repository config or officially document that Amazon Linux 2023 is no longer supported and recommend the el/8 workaround.
