Ubuntu 8.10更新源的方法及源的地址

备份一下源列表，进入终端，运行如下命令：
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

使用编辑器打开
sudo gedit /etc/apt/sources.list

清空里面的内容，选择下面提供的一到几个更新源地址，保存，然后刷新：
sudo apt-get update

刷新这一步不能少

在图形界面下更新源的方法：

依次点击“系统”－“系统管理”－“软件源”－“第三方软件（Other...）”，添加源的网址。这时你可以选择重新载入，系统也会自动进行检查是否有软件要更新，一旦系统检测到有要更新的软件，点击安装更新即可！
