Ubuntu安装后默认的官方源是美国的服务器，但是美国服务器在国内安装软件等会有较大的限制。所以我们需要将默认的源切换为国内源。一般来说，常用的国内源有阿里源（这是中国官方源）、网易源和搜狐源等等。除此之外，还有高校源，比如清华、中科大以及浙大等等。如果是在校学生，那么换成自己学校内部的源，更新和安装软件的速度会很快。如果是非校园网络，那么最推荐的就是阿里源。不同版本的Ubuntu系统的源列表不相同，在这里我只列举Ubuntu 16.04系统的源列表。

1. 更换源的两种方式

（1）打开系统设置选择，software&updates，如下：

然后在跳出来的框中点击选择”Download from：“选项

image

再点击other选项会出现一个choose a download server框并选择China，里面有很多国内服务器可选择。

（2）在sources.list文件中手动更改源，即将对应源列表中的代码复制到sources.list文件中，过程如下：

<1> 打开终端，通过cd指令进入sources.list文件所在目录。

$ cd /etc/apt

image

<2> 将原sources.list文件拷贝做备份，可以进入/etc/apt目录下看到有一个sources.list.bak文件。

$ sudo cp sources.list sources.list.bak

image

<3> 通过gedit指令对sources.list进行编辑（也可以用vim指令），并将sources.list文件中的内容全选删除，再把对应的源列表的内容复制到文件中。

$ sudo gedit sources.list
或 执行
$ sudo vi sources.list 进入 sources.list后 按 ggdG 快捷vi操作删除原文件内容

image

<4>访问源列表里的网址，并读取软件列表，然后更新保存在本地电脑，换源结束。

$ sudo apt-get update

国内的源地址
