package nvidia-dkms-390 (not installed) failed to install/upgrade: installed nvidia-dkms-390 package post-installation script subprocess returned error exit status 1

[Leif]

Happens after upgrading from ubuntu 16.04 to 18.04.

Kernel gets stuck at 4.13, and nvidia drivers won't install due to headers removed during installation.

For fixing in installation: Remove nvidia drivers before installing new kernel.

Steps to fix manually after upgrading:
Remove nvidia
Remove new kernel
Install new kernel
Reboot
Remove old kernel
Install nvidia
Reboot
