安裝kinetic版的moveit失敗或找不到相關包問題

我的系統是ubuntu16.04+kinetic，軟件源用的是易科的，軟件源請參考ROS的教程，我想安裝moveit，但是錯誤提示如下：

E: 中止安裝。

主要原因是軟件源的問題，推薦中科大的軟件源：

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'

然後：

sudo apt-get install ros-kinetic-moveit

更新環境：

source /opt/ros/indigo/setup.bash

然後啓動moveit的配置助手看看安裝是否成功：

roslaunch moveit_setup_assistant setup_assistant.launch

成功！
