VS Code连接Docker Dev Container失败：Shell服务终止及权限拒绝问题

此前可正常通过VS Code连接Docker容器，时隔数周再次连接同一容器时出现错误：

Error running command remote-containers.attachToRunningContainerFromViewlet: Shell server terminated (code: 255, signal: null)

已尝试更换、重新安装Dev Containers扩展，均无效。日志末尾提示Permission denied (publickey,password)，但未找到解决方法，寻求帮助。

终端日志 #

解决建议 #

1. 修复SSH密码弹窗工具的XSL错误 #

日志中反复出现的韩文提示意为“XSL文件路径或名称错误”，这是因为VS Code的SSH密码弹窗工具调用wmic时指定的英文XSL格式文件不存在（系统为韩文环境）。

• 打开管理员权限的命令提示符，执行以下命令复制韩文XSL文件到英文目录：

  mkdir "%WINDIR%\System32\wbem\en-us"
  copy "%WINDIR%\System32\wbem\ko-kr\csv.xsl" "%WINDIR%\System32\wbem\en-us\"
  

• 或直接改用SSH密钥认证，避免密码弹窗工具的调用。

2. 验证SSH基础连接 #

• 在本地终端手动执行ssh ycool.kwon@10.229.9.224，确认能否正常登录：
  • 若手动登录失败，检查服务器sshd_config是否开启密码登录（PasswordAuthentication yes），或本地公钥是否已添加到服务器~/.ssh/authorized_keys中。
  • 执行ssh-add -l查看本地已加载的SSH密钥，确认密钥是否正确配置。

3. 重置VS Code远程连接缓存 #

• 删除VS Code远程容器缓存目录：%APPDATA%\Code\User\globalStorage\ms-vscode-remote.remote-containers，移除对应容器的配置文件夹。
• 重新添加远程容器连接，手动输入服务器地址与认证信息。

4. 检查Docker容器状态 #

• 登录远程服务器后，执行docker ps确认/ycool.kwon_test容器是否正常运行，若已停止则重启容器后再尝试连接。
