kernel drivers are not installed

[KES]

When I install new kernel I get error:

run-parts: executing /etc/kernel/postinst.d/dkms 4.2.0-040200-generic /boot/vmlinuz-4.2.0-040200-generic
Error! Bad return status for module build on kernel: 4.2.0-040200-generic (x86_64)

After this and reboot the Virtual Box stops to work. I need deinstall/reinstall to reanimate it.

It is strange that error says vbox is 4.3.18, but my version is:

You are talking about the VirtualBox Guest Additions kernel modules. The Additions of VBox 4.3.18 do NOT support Linux 4.2.x (for obvious reasons). You have to upgrade the Guest Additions to version 4.3.30 or 5.0.2.
