前言:安装好ubuntu双系统后,默认的软件更新源是国外的,在国内使用速度很慢,用"apt install xxx"安装软件时可能出现"网络不可达"、"你的网络需要认证吗"、"无法定位软件包"等错误,所以我们需要更换成国内的源,这样才能正常安装和更新软件。 目录 一、ubuntu16.04更换国内源 1.备份原始源文件source.list 2.修改源文件sources.list 3.更新源 二、ubuntu18.04更换国内源 1.备份原始文件sources.list 2. 修改源文件sources.list 3. 更新源 三、Ubuntu ROS更换国内源 1.ubuntu16.04 1.1 清华源 2.ubuntu18.04 2.1 清华源 四、国内几个源的链接 一、ubuntu16.04更换国内源 1.备份原始源文件source.list桌面打开终端,执行命令:sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak 2.修改源文件sources.list(1)终端执行命令:sudo chmod 777 /etc/apt/sources.list 更改文件权限使其可编辑; (2)执行命令: sudo gedit /etc/apt/sources.list 打开文件进行编辑; (3)删除原来的文件内容,复制下面的任意一个到其中并保存(常用的是阿里源和清华源,推荐阿里源); 阿里源: deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse清华源: deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted un |
