Ruby on Rails部署报错：Could not read from remote repository求助

问题描述 #

此前通过Github Actions将代码从Github部署到AWS一直正常，相同代码突然失效，抛出Could not read from remote repository错误。已确认Github Actions可连接远程服务器，但无法从Github拉取最新代码。

使用的Gem列表 #

• gem 'capistrano-rails'
• gem 'capistrano', '~> 3.2'
• gem 'capistrano-rails-console', require: false
• gem 'capistrano-rails'
• gem 'capistrano-yarn'
• gem 'capistrano-bundler'
• gem "sshkit", "1.18.2"
• gem 'rails', '5.1.6.2'
• gem 来自仓库：https://github.com/miloserdow/capistrano-deploy/tree/v2.2

Github Actions配置 #

name:  Deployment
on:
  workflow_dispatch:
jobs:
  deploy_to_xyz:
    name: Deploy to xyz
    runs-on: ubuntu-20.04
    env:
      CAP_BRANCH: zzz
      AWS_KEY_ID: xxxx
      AWS_SECRET_KEY:  xxxx
      AWS_REGION:  xxxx
    steps:
    - uses: actions/checkout@v2
    - uses: ruby/setup-ruby@v1
      with:
        ruby-version: 2.5.9
        bundler-cache: true
    - uses: miloserdow/capistrano-deploy@v2.2
      with:
        target: staging
        enc_rsa_key_pth: "xxxx"
        deploy_key:  xxxx
    - name: Success
      # code related to failure
    - name: Fail deploy notification

可能的排查方向 #

• Deploy Key权限或有效性问题
  • 检查deploy_key对应的SSH密钥对是否过期、被撤销，或者公钥是否从Github仓库的Deploy Keys中被移除
  • 确认该Deploy Key拥有仓库的读取权限（私有仓库必须配置）
• 仓库地址或分支配置错误
  • 检查Capistrano配置中的repo_url是否正确，注意Github仓库地址大小写敏感，避免拼写错误
  • 确认环境变量CAP_BRANCH指定的分支zzz确实存在于目标仓库中
• SSH密钥传递问题
  • 检查miloserdow/capistrano-deploy插件的enc_rsa_key_pth和deploy_key参数是否配置正确，密钥内容需完整（包含正确的换行符，无多余空格）
  • 手动在远程服务器执行git ls-remote git@github.com:xxxx/xxxx.git HEAD，验证是否使用正确的密钥认证
• Github侧权限变更
  • 检查仓库访问权限是否被修改（如从公开转为私有），或组织权限调整导致Deploy Key失效
  • 确认AWS服务器的防火墙/安全组未拦截Github的IP地址（虽然能连接服务器，但拉取代码的出站请求可能被限制）
• 依赖缓存或版本冲突
  • 尝试在Github Actions中禁用bundler-cache: true，重新安装依赖后测试，排除旧版本缓存导致的兼容性问题
  • 确认sshkit 1.18.2版本与其他Capistrano插件无冲突
