不同的网络状况连接以下源的速度不同, 建议在添加前手动验证以下源的连接速度(ping下就行),选择最快的源可以节省大批下载时间。
首先备份源列表:
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
而后用gedit或其他编辑器打开:
gksu gedit /etc/apt/sources.list
kdesudo kate /etc/apt/sources.list
gksu mousepad /etc/apt/sources.list
gksu leafpad /etc/apt/sources.list (12.04版)
gksu gedit /etc/apt/sources.list
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
然后，刷新列表:
sudo apt-get update
注意：一定要执行刷新
