软件源sources更新出错，能上网，能ping通&&ROS Melodic安装&&KinetcV1

ubuntu显示的是17.04

但是竟然用17.10的源就好啦，去年有的问题，一年没怎么玩这个机子，突发奇想试试，就好了。。。。。。

首先错误如下:

我们没有key？？？什么鬼。如果有key导入就好。

1.那我想DNS是不是对的，现在来看，我能ping通也能打开网址应该可以，没问题。

2.我也让软件更新选择最佳源，结果不是链接网络失败就是其他国家的小服务器，更新也不会成功

3.那是不是版本问题？我看了一下17.04没问题，可是眼见不一定为实，想了想换着试试，竟然可以用。。。。

感觉中了奖，如果你想换，一定要备份再做！！！我之前换过一次名字改错了，搞了一天= =

修改如下:

sudo vim sources.list

竟然这样，不得不说猝不及防

内核？如下

uname -a
Linux E60-Server 4.10.0-42-generic #46-Ubuntu SMP Mon Dec 4 14:38:01 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

后记：ubuntu还是不要upgrade比较好，免得upgrade失败后问题一堆。对于大部分来说到这就能用了（建议升到18.04,毕竟17不再支持了），可是我是用来装ROS的。

首先，我先试了kinetic，报错。然后lunar，报错。难道我这个不支持ROS想想真是白开心一场,如下报错，一度绝望

我去这又是zesty ？？？好吧手工导入，换下ROS Melodic安装（支持ubuntu17.10版本）

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu artful main" > /etc/apt/sources.list.d/ros-latest.list'
sudo apt-get install ros-melodic-desktop-full

自此ubuntu能够安装ROS了，不过ROS最新版本好像是5月份才发稳定版。

然后安装KinetcV1驱动

source 一下setup.bash,然后

sudo apt-get install ros-kinetic-rgbd-launch

可以解决如下错误

roslaunch freenect_launch freenect.launch

rosrun rqt_image_view rqt_image_view
rosrun rviz rviz

depth/image_raw就是深度图了

前两天用了下激光雷达，然后官方操作是错误的，其实roslaunch的是时候已经包括了发布的名字。感觉激光雷达的code好几家都差不多。。
