Ubuntu 10.04 LTS 安装 sun-java6-jdk ，出现错误。
Reading 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
说是Ubuntu 10.04已经去掉 sun-java6-jdk 和 sun-java6-jre的软件包
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
sudo apt-get install sun-java6-jdk
错误提示还是一样：

这些都干过了。也查了源列表。。也有http://archive.canonical.com/ lucid partner，并且有了好几个。
求解。。。。
