To fix this issue users need to update the public key used for ROS apt repositories. To do this for ROS 1 installations one needs to run a single command, namely:
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
For ROS 2 installations you will need to run this command:
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg
本文介绍了如何修复Ubuntu系统中ROS2 apt仓库未签名的问题。用户需要更新ROS apt仓库的公共密钥,对于ROS 1,只需运行一个命令;而对于ROS 2,则需执行特定的命令。
