4.ubuntu换源

ubuntu换源

目的：ubuntu默认的源是国外的，使用apt-get的时候很慢，换成国内的源可以在安装软件时快很多很多。我用的是ubuntu16.04。

相关文件： /etc/apt/sources.list

步骤：

（1）.先备份这个文件（以防以后需要）

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

（2）.将文件中内容换成其他源（选一个源就行）

sudo nano /etc/apt/sources.list   ，把以前的内容删除，从下边的源中选一个复制粘贴。ctrl＋O保存，回车 确认，ctrl＋X退出，即可。（注：有的时候某个源换了也不好用，那就再换个别的试试）

（3）.命令行运行 sudo apt-get update ，更新一下就行了。
