我正在尝试构建 Raspberry Pi docker 映像，但我总是遇到相同的错误，类似于this、this和this。

在 a （或只是）apt update中以 root 身份运行命令时，我得到以下输出：arm32v7/ubuntu:20.04ubuntu:latest

我已经尝试了清理 apt、清理 docker 和删除/重新创建的建议解决方案，但均未/var/lib/apt/lists成功。SD 卡为 32G，操作系统为全新安装。df显示26G免费。

更多信息：

  • 这是在树莓派 4 B 上全新安装 2020-05-27-raspios-buster-lite-armhf 时发生的
  • 同样的错误发生在另一个运行 HypriotOS 的 Raspberry Pi 4 B 上
  • 相同图像中的相同命令在安装了 Arch linux 的树莓派 3 B 上运行良好
  • ubuntu:18.04如果我使用旧版本的 ubuntu ( , 16.04, 14.04) ，则不会发生该错误

我家里有多台机器，我想使用 SSH 和 VNC 从学校访问它们。为了做到这一点，我给了他们静态 IP：

  • 192.168.1.50：窗户
  • 192.168.1.51：Ubuntu
  • 192.168.1.52：树莓派/Raspbian

我知道 SSH 使用端口 22，所以我可以将此端口转发到路由器上的 192.168.1.51:22，但这样我将无法通过 SSH 连接到我的 Raspberry Pi。有什么方法可以设置它以访问两台机器？
