各位大佬 帮忙看看😥

@464122508 使用docker

@2730133417 在 第8章，启用imu数据后报错 中说：

直接不见了
报错如下
[ERROR] [cartographer_node-1]: process has died [pid 11537, exit code -6, cmd '/home/feng/chapt7/chapt7_ws/install/cartographer_ros/lib/cartographer_ros/cartographer_node -configuration_directory /home/feng/chapt7/chapt7_ws/install/fishbot_cartographer/share/fishbot_cartographer/config -configuration_basename fishbot_2d.lua --ros-args -r __node:=cartographer_node --params-file /tmp/launch_params_xsm0qb27'].

@firefirefox 请问我用的ros1，也是出现了校验数字签名时出错，可以用这个方法解决吗，我的系统是ubuntu20.04，哪一条指令是需要修改成自己的ubuntu版本或者ros1的对应版本呢？
