That kernel is obsolete, it's not in the repository any more.

Try these:

uname -a

Please, append its output to the question.

Update the kernel

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-generic

Reboot, check if kernel upgraded:

uname -a

Then see again with virtual box.
