安装sun-java6
添加partner源deb http://archive.canonical.com/ lucid partner 到/etc/apt/sources.list文件中
(或者 sudo add-apt-repository “deb http://archive.canonical.com/ lucid partner” 如果系统提示没有add-apt-repository命令，则需要先安装python-software-properties，命令sudo apt-get install python-software-properties。另外，有些版本的ubuntu即使安装了python-software-properties 也无add-apt-repository命令,此时需要手动添加此行"deb http://archive.canonical.com/ubuntu maverick partner"到/etc/apt/sources.list文件中。)

sudo apt-get update
