Linux – Can’t install guest additions to Lubuntu

I'm running Lubuntu as a virtual machine in virtual box.
The problem I'm getting is trying to install guest additions.

When I run uname -r I get:

3.11.0-14-generic

This is my log for /var/lib/dkms/vboxguest/4.2.4/build/make.log:

DKMS make.log for vboxguest-4.2.4 for kernel 3.11.0-14-generic (i686)

make: Leaving directory `/usr/src/linux-headers-3.11.0-14-generic'

I get this whenever I'm trying to apt-get install 3.11.0-14-generic, I get that error in the make. This is my log for the apt-get:
