ubuntu关于源的修改

ubuntu系统配置更新“源”

在ubuntu系统（其他linux系统，如Redhat,Open SUSE,Fedora Core也差不多）里，“源”就是指系统更新用的服务器，源地址，自然就是指更新服务器的地址了。 ubuntu“源文件”所在位置： /etc/apt 文件夹，名称：sources.list

1. 编辑源的文件：sudo gedit /etc/apt/sources.list

2. 更新源上的包：sudo apt-get update

3. 备份源的文件：sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

4. ubuntu系统ubuntu 8.10 台湾源。其他的都不稳定，大家想要的话，可以去网上搜索，很多的，我这里只给出我认为最稳定，速度也不错的台湾源：
