Verifying archive integrity... All good.
Uncompressing VirtualBox for Linux installation........
VirtualBox Version 1.4.0 (Wed Jun 6 00:03:39 CEST 2007) installation
Please install the build and header files for your current Linux kernel.
The current kernel version is 18.104.22.168-86
Problems were found which would prevent VirtualBox from installing.
Please correct these problems and try again.
Probably I have to install something. On the dutch forum Willem told me to install the kernel-headers package, but it's already installed.
Does anybody know what to do?
