Broken links inside Linux header file folder

Question

I installed the Linux header file for my kernel using command:

sudo apt-get install linux-headers-`uname -r`

In the folder

/usr/src/linux-headers-2.6.32-21-generic

all the files have broken links.

Example: The file linux-headers-2.6.32-21/crypto has broken link points to ../linux-headers-2.6.32-21/crypto.

Output of

ls -l /usr/src/linux-headers-2.6.32-21-generic :

Output of:

uname -r

2.6.32-21-generic

How should i fix this? (I want the headers files without broken links).

Answer 1

Those missing files in the /usr/src/linux-headers-2.6.32-21 directory are provided by the package linux-headers-2.6.32-21 . To get them, try installing that package.

If you want to install it from the command line, run:

sudo apt-get update && sudo apt-get install linux-headers-2.6.32-21

(The apt-get update part will help to make sure the system installs the package based in correct and consistent information about what packages are available from where and in what versions.)
