Ubuntu下无法安装sun-java6-jdk的解决办法

我确认了下我的sdk版本：

b748@b748-desktop:/$ java -version

java version "1.6.0_27"
OpenJDK Runtime Environment (IcedTea6 1.12.1) (6b27-1.12.1-2ubuntu0.10.04.2)

OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

显示我用的是OpenJDK，这导致我在做bulid的时候，总是失败。原因在于我需要的是需要sun java jdk。

安装方法如下：

sudo apt-get install sun-java6-jdk

echo " PATH=/usr/local/jdk1.6/bin:\$PATH:
CLASSPATH=/usr/local/jdk1.6/lib:.
JAVA_HOME=/usr/local/jdk1.6
export PATH CLASSPATH JAVA_HOME"
 >>/etc/bash.bashrc

但是安装这个sun java jdk的过程中出错：

安装 sun-java6-jdk出现以下错误

root@stu-system:/home# sudo apt-get install sun-java6-jdk
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

解决办法如下：

1、添加这个源：

deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse

方法：

sudo gedit /etc/apt/sources.list

打开源列表，在最后一行添加

deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse

保存退出。

2、更新apt源

sudo apt-get update

3、安装sun-java6-jdk

sudo apt-get install sun-java6-jdk

当出现：

The following NEW packages will be installed:
  gsfonts-x11 java-common odbcinst odbcinst1debian1 sun-java6-bin
  sun-java6-jdk sun-java6-jre unixodbc

我试过，惯用。
