先备份：sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
编辑源列表
gksu gedit /etc/apt/sources.list #(ed)ubuntu
kdesu kate /etc/apt/sources.list #kubuntu
gksu mousepad /etc/apt/sources.list #xubuntu
sudo vim /etc/apt/sources.list #通用
从以下各服务器列表内容中选择一段替换文件中的所有内容，一般来说加入一至两组即可，加多了影响更新速度。为防止非官方源中软件包不全的问题，请在sources.list文件中尾部添加一组官方源。
保存后更新。 sudo apt-get update[code]#Archive.ubuntu.com更新服务器（欧洲，此为官方源，电信网通用户使用)：
