ubuntu顯示的是17.04
但是竟然用17.10的源就好啦，去年有的問題，一年沒怎麼玩這個機子，突發奇想試試，就好了。。。。。。
首先錯誤如下:
忽略:76 http://mirrors.aliyun.com/ubuntu zesty-updates/multiverse all Packages

我們沒有key？？？什麼鬼。如果有key導入就好。
1.那我想DNS是不是對的，現在來看，我能ping通也能打開網址應該可以，沒問題。
2.我也讓軟件更新選擇最佳源，結果不是鏈接網絡失敗就是其他國家的小服務器，更新也不會成功
3.那是不是版本問題？我看了一下17.04沒問題，可是眼見不一定爲實，想了想換着試試，竟然可以用。。。。
感覺中了獎，如果你想換，一定要備份再做！！！我之前換過一次名字改錯了，搞了一天= =

竟然這樣，不得不說猝不及防
內核？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
後記：ubuntu還是不要upgrade比較好，免得upgrade失敗後問題一堆。對於大部分來說到這就能用了（建議升到18.04,畢竟17不再支持了），可是我是用來裝ROS的。
首先，我先試了kinetic，報錯。然後lunar，報錯。難道我這個不支持ROS想想真是白開心一場,如下報錯，一度絕望
我去這又是zesty ？？？好吧手工導入，換下ROS Melodic安裝（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能夠安裝ROS了，不過ROS最新版本好像是5月份才發穩定版。
然後安裝KinetcV1驅動
source 一下setup.bash,然後
sudo apt-get install ros-kinetic-rgbd-launch
可以解決如下錯誤
roslaunch freenect_launch freenect.launch
rosrun rqt_image_view rqt_image_view
rosrun rviz rviz
depth/image_raw就是深度圖了

前兩天用了下激光雷達，然後官方操作是錯誤的，其實roslaunch的是時候已經包括了發佈的名字。感覺激光雷達的code好幾家都差不多。。
