运行 sudo apt update的时候出现下面的错误:

Err:11 http://packages.ros.org/ros2/ubuntu xenial InRelease                                                             
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654

或者:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://packages.ros.org/ros2/ubuntu focal InRelease: The following signatures were invalid: EXPKEYSIG F42ED6FBAB17C654 Open Robotics <info@osrfoundation.org>

W: Some index files failed to download. They have been ignored, or old ones used instead.

试了一些办法,包括

sudo apt-key del F42ED6FBAB17C654

显示是ok,但是update之后还是会提示错误。

试了

sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

还是不行。

试了:

curl http://repo.ros2.org/repos.key | sudo apt-key add -

还是不行.

最后解决办法:

ROS1:

curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

ROS 2 :

sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg

然后就ok了。


补充:

raspi4上用的是以下指令:

curl http://repo.ros2.org/repos.key | sudo apt-key add -
