ubuntu16.04更換鏡像源為阿裏雲鏡像源

1.首先Ctrl+Alt+T打開終端,輸入cd /etc/apt/ 輸入ls命令看到有一個sources.list文件,備份它:cp sources.list sources.list.old
2.打開阿裏雲鏡像站[https://developer.aliyun.com/mirror/],找到ubuntu,點擊右邊的幫助,複制如下軟件源代碼:(ubuntu18.04自行複制對應版本)

deb http://mirrors.aliyun.com/ubuntu/ xenial main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial universe




deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main




deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security universe

3.用vim打開: sudo vim sources.list 輸入ggdG刪除所有內容,按i鍵進入插入模式,鼠標右鍵粘貼,按Esc切換到命令模式,輸入:x回車退出,至此更換鏡像源完成.
4.終端輸入sudo apt-get update更新鏡像源
