1.The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 425956BB3E31DF51
这个错误常伴 吾身
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 425956BB3E31DF51 搞定
2.tar 命令
传送门 https://www.cnblogs.com/wangluochong/p/7194037.html
3.rosweb
https://answers.ros.org/question/288585/creating-a-web-interface-for-a-ros-robot/
4.dns 不通
通过/etc/network/interfaces，在它的最后增加一句：
dns-nameservers 8.8.8.8 复制就好，很多人拼写错误
5.samba配置
https://blog.csdn.net/sunye8910/article/details/81177298
6.git clone 慢的问题
https://www.ipaddress.com/ip-lookup
查下ip github.global.ssl.fastly.net 和github.com
然后再/etc/hosts 文件后面加
sudo /etc/init.d/networking restart 刷新下dns ，搞定，好多帖子都是骗人的
7.缺serial的问题
我要是再装成rossrial我把电脑吃了
https://github.com/wjwwood/serial 源码再这里
先改下makefile 文件
然后就make; make install
8 BULLET_SOFTBODY_LIBRARY 没有
装就是了rosdep where-defined bullet;sudo apt-get install libbullet-dev
9 Could NOT find SDL (missing: SDL_LIBRARY SDL_INCLUDE_DIR)
sudo apt-get install libsdl1.2-dev
10Could NOT find SDL_image (missing: SDL_IMAGE_LIBRARIES
sudo apt-get install libsdl*
11.Could not find the required component ‘pcl_ros’
sudo apt-get install libpcl-dev
12gtk 错误
sudo apt-get install gtk2-engines-murrine
放弃了，能装上去，一些视觉的包搞不定，以后有机会再搞吧
