无法从Visual Studio调试部分机器的远程Docker：VsDbgRemoteUnixLauncher仅支持远程Unix机器

在Ubuntu机器的Linux Docker容器中运行.NET 7应用，无法从Windows 11的Visual Studio附加调试，但能正常连接其他Ubuntu机器Docker里的.NET应用。

报错信息：

Failed to launch debug adapter 'coreclr'.
VsDbgRemoteUnixLauncher only supports remote Unix machines!

“附加到进程”向导能看到容器及其中的进程，说明SSH连接正常，但网上找不到该错误的相关信息。

执行命令DebugAdapterHost.Logging /On /OutputWindow后，调试适配器主机日志输出如下：

• 验证目标Ubuntu机器的系统标识
  执行uname -a命令，确认输出的内核信息为标准Unix/Linux格式。若输出异常，需修复系统的操作系统标识配置，避免Visual Studio误判目标系统类型。

• 重置Visual Studio远程调试缓存

  1. 关闭Visual Studio，删除%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\<你的VS版本号>\RemoteDebugger目录下的所有缓存文件
  2. 重新启动Visual Studio，重新添加远程Ubuntu机器的连接配置，确保选择的目标类型为Unix

• 升级Visual Studio到最新稳定版
  当前使用的DebugAdapterHost版本为17.6.10530.1，该版本可能存在适配bug。升级到Visual Studio 2022的最新版本，修复已知的远程调试兼容性问题。

• 排查Docker容器网络配置
  尝试将容器切换为host网络模式，再尝试附加调试，排除端口映射或网络隔离导致的调试请求异常。

• 手动部署vsdbg调试工具
  手动下载与Visual Studio版本匹配的vsdbg工具，放置到Ubuntu机器的~/.vs-debugger/vs2022目录，避免自动部署时出现版本不兼容或文件损坏问题。
