安装了最新版的Ubuntu之后，本人就开始了Ubuntu 10.10的折腾之旅。客观的说，启动速度和关机速度还是相当快的。打开Firefox之后的第一件事就是安装五笔输入法，没有软件源的Ubuntu显示很是无能为力，那就添加比较快的Ubuntu 10.10的更新源，下面就是apt-get的天下了。
1、备份原来的Ubuntu 10.10源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bk
2、添加Ubuntu 10.10更新源(见图1)
sudo gedit /etc/apt/sources.list

编辑你的源列表，将原来的内容全部删除，添加第2页列表中最适合你的源(注意不要全部添加)，选择一个最合适你的即可，复制到你的列表中，然后保存列表。
3、更新源列表信息(见图2)
sudo apt-get update
