Unbuntu 12.04 安装sun-java6-jdk的问题

[silentwins]

试了无数种方法，加ppa，加repo，都是不行

anonymous@ubuntu:~$ sudo apt-get install sun-java6-jdkReading package lists... Done
Building dependency tree       
Reading state information... Done
Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'sun-java6-jdk' has no installation candidate

大家有成功的没有？请不吝赐教！
为什么一个这么常用的东西会这么麻烦？就因为sun被收购了？
sun-java-jdk会不会跟oracle-java-jdk有区别啊？
我只想要sun-java6-jdk，安装不上这个没法玩了，请大家帮忙一下，非常感谢！
