ubuntu安装jdk遇到一个问题
问题描述：
sudo apt-get install sun-java6-jdk
出现如下信息：
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

问题解决：
1. sudo gedit 打开 /ect/apt/sources.list
2. 最后加入一行
“deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse” 保存关闭。
3. sudo apt-get update
4。sudo apt-get install sun-java6-jdk

解决拉。。
