Ubuntu系統修改資源爲阿里雲鏡像

通常都會推薦使用國內的鏡像源，好比163或者阿里雲的鏡像服務器
將下列文本添加到/etc/apt/sources.list文件裏

deb http://mirrors.aliyun.com/ubuntu/ raring main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ raring-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ raring-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ raring-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ raring-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ raring main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ raring-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ raring-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ raring-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ raring-backports main restricted universe multiverse

可是執行sudo apt-get update仍然報錯，問題在於DNS沒有配置好。
解決方法：

sudo vi /etc/resolv.conf

添加

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
#這裏用的是阿里雲的DNS服務器
nameserver 223.5.5.5
nameserver 223.6.6.6

以後執行sudo apt-get update就正常了。
