原始源进行备份。

打开终端，输入以下命令以备份原有的配置文件（可选）：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

编辑源文件配置文件：

sudo nano /etc/apt/sources.list

在文件中找到相应的镜像源地址，注释掉原有的地址，并添加新的地址。

例如，要将默认的镜像源修改为清华大学的镜像源，可以将原有的地址注释掉（在前面加上#），并添加以下内容：

// 接着进入清华镜像源网站： https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/

// 清华# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

保存文件并退出编辑器。更新软件包列表：

sudo apt-get update

实操中的问题与解决方案：

1、换源时的问题：

因为ROS安装采用的鱼香的快捷安装方法。

// 在换源过程中，通过修改该list内容来实现换源。

/etc/apt/sources.list

// 修改好后保存退出，然后执行update

sudo apt-get update

// 可一直在此过程报错，

403 E: 仓库 “http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu bionic InRelease”

E: 仓库 “https://mirrors.tuna.tsinghua.edu.cn/ros2/ubuntu bionic Release” 没有 Release 文件_无法解析域名“mirrors.tuna.tsinghua.edu.cn”

解决方法：

// 将如下路径下的文件进行处理

/etc/apt/sources.list.d/ros-fish.list

// 在此路径下执行：【也就是相当于将 ros-fish.list 删除】

hzx@vm:/etc/apt/sources.list.d$ sudo mv ros-fish.list ros-fish.list.bak

// 之后在/etc/apt/sources.list 文件内各种换源，然后进行 update 可以成功。

sudo apt-get update

2 sudo apt-get install ***package 无法定位软件包

在源码安装某包时，在catkin_ws/src 下执行 catkin_make时，会有出现如下报错：

很明显，就是缺少“moveit_visual_tools”包的依赖，安装即可以，

可以通过如下安装缺失的依赖包

<code>// 常规操作

sudo apt-get install ros-melodic-moveit-visual-tools

// 但出现如下问题：

这就说明在这个源下没有这个依赖包，需要换源。但此操作不同于【 经验 1、换源时的问题】，需要作如下修改：参考：ROS中无法定位软件包问题

<code>// 进入到该路径下，创建/打开这个list文件，

/etc/apt/sources.list.d/ros-latest.list

// 将如下填入文件内。【使用中科大的源，也可以尝试其他源】

deb https://mirrors.ustc.edu.cn/ros/ubuntu/ bionic main

<code>// 再次进行安装，发现有了这个依赖包

sudo apt-get install ros-melodic-moveit-visual-tools

最终，在catkin_ws/src 下执行 catkin_make时，不会出现报错。
