Ubuntu 12.04LTS 下安装JAVA-JDK

今天再一次尝试Ubuntu系统，安装的是Ubuntu12.04LTS

麻烦的是 Ubuntu默认是不开启root用户的，需要使用：su passwd root 来启用root

然后自己想搭建Android开发环境，需要安装JAVA JDK，在root权限下：

apt-get install sun-java6-jdk

但是找不到下载源，通过google，找到了源：

1、添加这个源：
add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse"
2、sudo apt-get update
 
3、sudo apt-get install sun-java6-jdk
 
然后就会出现下载安装sun-java6-jdk。。。有点久

在Ubuntu12.04 Desktop Release Notes中提到：

Java Toolchain

The default run time for Java is OpenJDK 6b24 (IcedTea 1.11.1). OpenJDK 7u3 (IcedTea 2.1) is available in the archive as well.

但是没有给出替代的下载源

在Ubuntu10.04 Desktop Release Notes中提到：

Sun Java moved to the Partner repository

 

For Ubuntu 10.04 LTS, the sun-java6 packages have been dropped from the Multiverse section of the Ubuntu archive. It is recommended that you use openjdk-6 instead.

If you can not switch from the proprietary Sun JDK/JRE to OpenJDK, you can install sun-java6 packages from the Canonical Partner Repository. You can configure your system to use this repository via command-line:

     add-apt-repository "deb http://archive.canonical.com/ lucid partner"
