0 ubuntu常见的源列表（选择合适的源可加快更新速度－转）

  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(Then what's the fastest source for Beijing Netcom? ),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

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:
(源列表在下方，自己选择吧)

4 然后，刷新列表:

sudo apt-get update
