如何得到UBUNTU源代码

在按书作测试，有难点一一解决。

Ubuntu's Source code can be found here http://archive.ubuntu.com/

And to access kernel source code:
1. Make sure you have the source code repository enabled. To do this, go to System>Administration>Software Sources and check the source code repository. Reload the package information.

2. Open a terminal window and type

sudo apt-get install linux-source-2.x.xx

Replace 2.x.xx with the kernel version. If you don't know what your kernel version is, use the following command:

uname -r

The output will be something like this "2.6.27-9-generic"

In this case you will have to replace 2.x.xx with 2.6.27
