这是我的/etc/apt/source.list.列表：

deb http://archive.ubuntu.com/ubuntu/ jaunty main restricted universe
deb-src http://archive.ubuntu.com/ubuntu/ jaunty main restricted universe
deb http://archive.ubuntu.com/ubuntu/ jaunty-updates main restricted universe
deb-src http://archive.ubuntu.com/ubuntu/ jaunty-updates main restricted universe
deb http://security.ubuntu.com/ubuntu jaunty-security main restricted universe
deb-src http://security.ubuntu.com/ubuntu jaunty-security main restricted universe
deb http://us.archive.ubuntu.com/ubuntu dapper main restricted
deb http://us.archive.ubuntu.com/ubuntu dapper universe multiverse.

注意多重宇宙在里面！为什么Java不安装！？

Answer 1

在最后两行中将dapper更改为jaunty，或确保为其中一个jaunty行启用了multiverse。

Answer 2

或者，您也可以使用其他jvm，例如：

sudo aptitude install openjdk-6-jre

Answer 3

为什么不直接去java.sun.com下载呢？您将得到一个二进制包装的shell脚本。将它复制到要安装它的地方，比如/usr/local/ and。(假设文件名为jdk-sun-1.6.bin)

cd /usr/local/ sh jdk-sun-1.6.bin

它将要求您接受许可，并在jdk-sun-1.6目录中提取整个jdk。现在，将您的$PATH编辑为/usr/local/jdk-sun-1.6/bin。如果您想使用更新的或更旧的版本，只需将jdk-sun-1.6吹开，或者在它旁边安装另一个jdk并更改路径即可。

我更喜欢直接从Sun站点安装JDK，而不是从apt实用程序安装JDK。它被控制在一个地方，你可以完全控制它。
