如何使用Ubuntu推荐的源

不同的网络状况连接以下源的速度不同, 所以cn99并不一定是最快的源,建议在添加前手动验证以下源的连接速度(ping下就行),比如说北京网通ADSL用户连接cn99就非常慢,而ftp.sjtu.edu.cn是相对较快的源,选择最快的源可以节省大批下载时间

1 首先备份源列表:

sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

2 而后用gedit或其他编辑器打开:

 gksu gedit /etc/apt/sources.list
 kdesu kate /etc/apt/sources.list  
 gksu mousepad /etc/apt/sources.list
 gksu gedit /etc/apt/sources.list

3 从下面列表中选择合适的源，替换掉文件中所有的内容，保存编辑好的文件:

注意：一定要选对版本 8.10 8.04 7.10 6.06

4 然后，刷新列表:

sudo apt-get update

注意：一定要执行刷新
