GitHub Action提示Unable to resolve action，能否回退Runner镜像版本？

我配置的GitHub Action如下：

name: action-name

on: workflow_dispatch

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-evaluation@v4
        with:
          python-version: '3.11'

几天前"Set up job"环节运行正常，日志如下：

Current runner version: '2.311.0'

目前仅发现Runner镜像版本变化，不清楚失败原因，请问能否回退到之前的镜像版本？

1. 根本错误原因 #

你配置的Action里写的是actions/setup-evaluation@v4，但这个仓库不存在——之前正常运行时，实际下载的是actions/setup-python@v4，说明这是手误写错了Action名称，和Runner镜像版本无关。

2. 直接修复方法 #

把错误的Action名称修正为正确的actions/setup-python@v4，修改后的Workflow如下：

name: action-name

on: workflow_dispatch

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-python@v4
        with:
          python-version: '3.11'

3. 关于回退Runner镜像版本 #

虽然这次问题和镜像无关，但确实可以指定特定版本的Runner镜像。对于Ubuntu 22.04，你可以通过runs-on字段指定镜像版本，格式为ubuntu-22.04-<版本号>，比如你之前的版本写法如下：

jobs:
  build:
    runs-on: ubuntu-22.04-20231030.2.0

不过官方不建议长期固定旧镜像，因为旧镜像可能存在安全漏洞，修复Action名称才是解决当前问题的正确方式。
