安装kinetic版的moveit失败或找不到相关包问题

我的系统是ubuntu16.04+kinetic，软件源用的是易科的，软件源请参考ROS的教程，我想安装moveit，但是错误提示如下：

主要原因是软件源的问题，推荐中科大的软件源：

sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.ustc.edu.cn/ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'

然后：

sudo apt-get install ros-kinetic-moveit

更新环境：

source /opt/ros/indigo/setup.bash

然后启动moveit的配置助手看看安装是否成功：

roslaunch moveit_setup_assistant setup_assistant.launch

成功！
