好不容易解決install.sh的問題

又碰到一個怪東西...在第三步驟remove driver

最後出現下面的錯誤

diff: /tmp/Sk98IWnJOqcPnIGmEfLcIhMrW/config-bk2: No such file or directory
diff: /lib/modules/2.6.31-14-generic/source/.config: No such file or directory
Check modpost availability (not available) [ warn ]

The kernel's modpost utility is not available. Addtionally we did not
even find the source code for the utility. For this situation it exists
only one reason: your kernel source tree is corrupted.

You may continue to check for the modpost.c file below the directory
/usr/src/linux/scripts/mod. Normally you should find here also a binary
called modpost. Both seem to be missing.

Please contact your distribution vendor or download a kernel from
kernel.org to build your own kernel manually. It then will contain the
missing utility.

請問這又是什麼東西 我應該怎樣解決呢
