1 解决Unbuntu上安装ROS特别慢问题

在安装ROS的时候速度特别慢，显示需要时间可能需要一天多，网上查看提示可以更换下载ros的镜像源：

1.1 Ubunut 更换ROS的镜像源为国内的镜像源

WIKI上有给出ROS的国内镜像源

1、中国科学技术大学 ros镜像源

sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.ustc.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'

2、清华大学 ros镜像源

sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'

3、北京外国语大学ros镜像源

sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.bfsu.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'

4、上海交通大学 ros镜像源

sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.sjtug.sjtu.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'

我用的是清华的镜像源，真的很快，嗖的一下

1.2 如果是Mint19.3系统，请参考如下添加ros镜像源

由于我的系统是Mint19.3，是Ubuntu改造出来的系统，对应的Ubuntu版本为Ubuntu18.04，因此对因的Ubuntu版本号为bionic，具体添加如下：

sudo sh -c 'echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ bionic main" > /etc/apt/sources.list.d/ros-latest.list'

2 ROS安装过程sudo rosdep init+rosdep update出现错误:‘The read operation timed out’

参考

解决方法：

1、删除之前的源文件

sudo rm /etc/ros/rosdep/sources.list.d/20-default.list

2、更新

sudo apt-get update

3、rosdep初始化

sudo rosdep init

4、rosdep再次更新

rosdep update

具体操作返回信息如下：
