Question: 构建失败：Docker 无法从 registry-1.docker.io 拉取 ubuntu:22.04（i/o timeout）。已备份并移除 /etc/systemd/system/docker.service.d/proxy.conf 为 proxy.conf.bak 并重启 Docker。下一步怎么处理？请选择：

Choices:
- 在本机重试：允许我尝试多种拉取策略（强制 IPv4/直连 docker pull 并重试构建）
- 你上传 ubuntu:22.04 镜像 tar 到 /home/longshao/docker-opencode/ubuntu_22.04.tar，我来 docker load 后继续构建
- 在另一台可联网主机构建并把最终 opencode_local.tar 传回内网（我提供构建命令）
- 提供公司/本地 Registry 镜像加速器地址，我来配置 Docker 并重试
- 停止（不继续）

已停止进一步操作。总结当前状态与建议：

- 已在 /etc/systemd/system/docker.service.d/proxy.conf.bak 备份原 proxy 配置并删除原文件，Docker 已重启（这会短暂中断运行容器）。
- 现在的错误是从 Docker Hub 拉取 ubuntu:22.04 超时（i/o timeout），表示主机到 Docker Hub 的网络被阻断或受限（公司防火墙/出网策略）。
- 可选解决方案（供参考）：
  - 在可联网的主机上构建镜像并传入内网（推荐离线流程）；或
  - 由你提供可访问的 registry/mirror 或 ubuntu 镜像 tar，我在当前主机 docker load 后继续构建；或
  - 在本机通过代理或启用公网访问时重试（需要能访问 registry-1.docker.io）。

需要我按某个选项继续操作？
