ubuntu换源

ubuntu换源方法

方法1. 图形界面配置（新手推荐）

依次打开：系统设置，软件和更新。在下载自中选择其他站点，然后在中国的条目下选择 mirrors.ustc.edu.cn。

下面是 Ubuntu 16.04 的操作示意图（以中科大源为例）：

方法2. 手动更改配置文件

一般情况下，将/etc/apt/sources.list文件中 Ubuntu 默认的源地址http://archive.ubuntu.com/替换为http://mirrors.ustc.edu.cn/即可。（注意：替换后的网址为中科大源网址，如需更换为其他源，请替换为相应源的网址。）

2.1 命令行替换

可以使用如下命令：

1. sudo sed -i 's/archive.ubuntu.com/mirrors.ustc.edu.cn/g' /etc/apt/sources.list

复制代码

Ubuntu 图形安装器会根据用户设定的时区推断 locale，这导致默认的源地址通常不是http://archive.ubuntu.com/，而是http://.archive.ubuntu.com/ubuntu/，如http://cn.archive.ubuntu.com/ubuntu/，此时只需将上面的命令进行相应的替换即可，即sudo sed -i 's/cn.archive.ubuntu.com/mirrors.ustc.edu.cn/g' /etc/apt/sources.list。

当然也可以直接编辑 /etc/apt/sources.list 文件（需要使用 sudo）。以下是 Ubuntu 20.04 参考配置内容：

2.2 手动替换

直接编辑/etc/apt/sources.list文件（需要使用 sudo）:
将原文件做备份：

1. sudo cp /etc/apt/sources.list /etc/apt/sources_copy.list

复制代码

打开文件：

1. sudo gedit /etc/apt/sources.list

复制代码

将文件中的内容删除，将镜像源复制到里面。镜像源参考下一章节ubuntu镜像源。

点击保存（或Ctrl+s）。

更新：

1. sudo apt-get update
2. sudo apt-get upgrade

复制代码

ubuntu的镜像源

每个版本的代号：

• 22.04：jammy；
• 20.04：focal；
• 18.04：bionic；
• 16.04：xenial；
• 14.04：trusty。

如果电脑为X86系统（一般都为X86），使用下面镜像源就可以使用，如果为ARM架构，便使用ubuntu-ports镜像。两着镜像源唯一区别是，X86系统的镜像源网址结尾为/ubuntu/，而ARM架构的镜像源网址结尾为ubuntu-ports，只要将下面镜像源修改即可，例如将http://mirrors.aliyun.com/ubuntu/修改为http://mirrors.aliyun.com/ubuntu-ports/。
