无法在 RPI 4 运行 Ubuntu 21.10 上安装 ROS2 Foxy
Unable to install ROS2 Foxy on RPI 4 running Ubuntu 21.10
我无法运行命令 sudo apt install ros-foxy-desktop。按照此处的指南操作：https://docs.ros.org/en/foxy/Installation/Ubuntu-Install-Debians.html。我能够完成所有步骤，直到出现这些错误的最终安装。
如有任何帮助，我们将不胜感激。我已经尝试按照这里的指南安装 https://docs.ros.org/en/foxy/Installation/Ubuntu-Development-Setup.html。是不是因为我是运行ning ubuntu 21.10桌面，需要运行ning 20.04服务器？我 运行 使用 20.04 服务器的问题是我无法连接到我所在的大学的 wifi，wifi 使用 PEAP，我不知道如何通过服务器设置它连接到 wifi。

目前 Foxy 是为 20.04 构建的，因此没有可以安装的 21.04 版本。您将必须安装 20.04 或 运行 某种容器（即 docker）。
至于 PEAP 身份验证，我可能会查看 this askubuntu 线程。
