Hit:5 https://mirrors.ustc.edu.cn/ubuntu jammy-proposed InRelease

Get:6 http://packages.ros.org/ros2/ubuntu jammy InRelease [4,682 B]

Err:6 http://packages.ros.org/ros2/ubuntu jammy InRelease

  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654

Reading package lists... Done

W: GPG error: http://packages.ros.org/ros2/ubuntu jammy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654

E: The repository 'http://packages.ros.org/ros2/ubuntu jammy InRelease' is not signed.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and user configuration details.

原因添加ROS 2 GPG key 失败了,https://raw.githubusercontent.com/ros/rosdistro/master/ros.key这个文件墙内获取不了,所以正确方法是不要学ROS了,获取这个key是高风险行为,Over
