【Ubuntu 】Ubuntu 更换国内源—解决终端下载错误或速度慢的问题「建议收藏」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”aptinstallxxx”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更换国内源二、ubuntu18.04更换国内源三、UbuntuROS更换国内源

大家好,又见面了,我是你们的朋友全栈君。

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。

 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);

3.更新源

桌面终端执行命令:sudo apt update更新软件列表,换源完成。

二、ubuntu18.04更换国内源

1.备份原始文件sources.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,内容可以去博客复制);
