I noticed that the old version of ngSpice is being used with the kicad_5.0.2 package from the repository (that does not support VDMOS models).
So, I made a new version of the package libngspice-kicad with ngSpice 30. I used the original source package and just replaced the source code of ngSpice, incremented the version numbers and added new entry in the changelog.
libngspice-kicad_0.2-30_amd64.deb (1.9 MB)
libngspice-kicad_0.2-30_amd64.deb.sha512sum (166 Bytes)
I also built again the kicad_5.0.2 package. The kicad_5.0.2 from the repository is working with the new library, however I am not sure if it’s correct to use it with the newer ngspice library.
Download from Google Drive (download all at once link):
Packages are built on Ubuntu 16.04.5 LTS.
First, I built and installed the new version of the ngspice library (version 30):
$ sudo dpkg -i libngspice-kicad_0.2-30_amd64.deb
$ sudo dpkg -i libngspice-kicad-doc_0.2-30_amd64.deb
Then, I installed most of the packages from the repository (except kicad - note the sign “-” after the “kicad”):
$ sudo apt-get install kicad-doc-en kicad-footprints kicad-packages3d kicad-symbols kicad-templates kicad-
Then, I built and installed my version of the kicad.
$ sudo dpkg -i kicad_5.0.2-stable-201811280958+bee76a0~70~ubuntu16.04.1_amd64.deb
Here is the list of installed “kicad” packages on my system:

I did not rebuilt all the packages, because I think there is no need to do it.
I did not installed kicad-dbg_5.0.2 and kicad-demo_5.0.2, because they are not critical.

I tested it and it works with some subcircuits. But with other subcircuits KiCad crashes (segmentation fault).
Example of subcircuit that induces crash:
.SUBCKT Transistor 1 2 3
M5 1 2 3 Si4842DY
.model Si4842DY VDMOS(Rg=3 Rd=2.4m Rs=1.8m Vto=2 Kp=98 Cgdmax=1n Cgdmin=.13n Cgs=1.7n Cjo=.5n Is=50p Rb=3m mfg=Siliconix Vds=30 Ron=6m Qg=25n)
.ENDS Transistor
Example of subcircuit that does not induce crash (but is wrong and the program return error message):
.SUBCKT Transistor 1 2 3
V5 1 2 3 Si4842DY
.model Si4842DY VDMOS(Rg=3 Rd=2.4m Rs=1.8m Vto=2 Kp=98 Cgdmax=1n Cgdmin=.13n Cgs=1.7n Cjo=.5n Is=50p Rb=3m mfg=Siliconix Vds=30 Ron=6m Qg=25n)
.ENDS Transistor
The error message is:
Error on line 0 :
v.xm1.v5 vds vgs 3 3 si4842dy
unknown parameter (3)
Archive of the project (if you want to test it).
When I use transistors defined as MOSFET (without subcircuit) it works. For example:
.model Si4842DY VDMOS(Rg=3 Rd=2.4m Rs=1.8m Vto=2 Kp=98 Cgdmax=1n Cgdmin=.13n Cgs=1.7n Cjo=.5n Is=50p Rb=3m mfg=Siliconix Vds=30 Ron=6m Qg=25n)
