Ubuntu Server 14.04配置apt-get源

1.在安装Ubuntu系统时候我们已经安装了ssh服务，所以直接xshell连接到ubuntu

2.下面进行apt-get源配置

注意：我们平时修改配置文件时候一定要先备份下原来的配置文件

• 备份源：

zzq@ubuntu:~$ sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

• 配置源：

zzq@ubuntu:~$ sudo vim /etc/apt/sources.list 

首先清空里面得到所有内容
然后写上国内比较好的源：中科大源、阿里源

• 升级源：

首先更新软件列表

zzq@ubuntu:~$ sudo apt-get update

然后更新软件

zzq@ubuntu:~$ sudo apt-get upgrade 

此时ubuntu源配置就OK了！
