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.geek-share.com/detail/2711272280.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
