華為源
1、備份配置文件： sudo cp -a /etc/apt/sources.list /etc/apt/sources.list.bak 2、修改sources.list文件，將http://archive.ubuntu.com和http://security.ubuntu.com替換成http://repo.huaweicloud.com，可以參考如下命令： sudo sed -i "s@http://.*archive.ubuntu.com@http://repo.huaweicloud.com@g" /etc/apt/sources.list sudo sed -i "s@http://.*security.ubuntu.com@http://repo.huaweicloud.com@g" /etc/apt/sources.list 3、執行apt-get update更新索引
官方源
自帶/etc/apt/sources.list 文件中內容
選擇任意一個替換文件中的內容
3、執行更新
sudo apt-get update sudo apt-get upgrade
