ubuntu 更换数据源

ubuntu16.04LTS更换阿里源

1.直接在原文件中修改
sudo vim /etc/apt/sources.list
替换：

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted
deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse

2. 在etc/apt中找到source.list文件下载到本地

　　用新的数据源替换原来的内容，保存，因为没有权限的问题，所有先把修改后的文件上传到home/ubuntu/目录下 ,

　　执行 sudo cp -r /home/ubuntu/source.list /etc/apt/source.list （替换掉etc/apt下的source.list文件）
更新：
sudo apt-get update

如果报以下类似的错误，是因为解析域名不成功

Err:1 http://archive.canonical.com/ubuntu xenial InRelease
Temporary failure resolving ‘archive.canonical.com‘

此时运行：sudo vim /etc/resolv.conf

添加：nameserver 8.8.8.8

即可
