“VBoxManage: error: Failed to create the VirtualBox object Code NS_ERROR_FACTORY_NOT_REGISTERED (0x80040154)” error while creating local dcos environment using vagrant in Ubuntu Linux 17.04 and 18.04

[rajcspsg]

I'm trying to follow the steps here to install minidcos locally using vagrant.

I've installed minidcos using the below command here -

$ curl --fail -L https://github.com/dcos/dcos-e2e/releases/download/2018.12.10.0/minidcos -o /usr/local/bin/minidcos && \
  chmod +x /usr/local/bin/minidcos
minidcos vagrant doctor command output is

$ minidcos vagrant doctor
5/5 checks complete: ██████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████rajkumar@rajk$ minidcos vagrant create ./dcos_generate_config.sh --agents 0 
I assumed the above command is successfully snce there is no error in the output.


$ sudo minidcos vagrant create ./dcos_generate_config.sh --agents 0

From the above error log I thought VBoxManage list vms command failed.
So I executed manually but it is working fine.

$ VBoxManage list vms

"OpenSuseTumbleweed" {91f9de56-7a48-4dfe-9f3f-7cf6b764a0d1}

My minidcos version installed in my laptop is

$ minidcos --version
minidcos, version 2019.01.21.0

My ubuntu version is :

$ lsb_release  -a
Distributor ID: Ubuntu
Description:    Ubuntu 17.10
Release:        17.10
Codename:       artful

I've asked the same question in stackoverflow as well.

minidcos works on mac OS sierra with both virtual box 5.1.x, 5.2.x and 6.0.x
minidcos work on ubuntu 16.04 and virtualbox 5.1.x and 5.2.x
minidcos doesn't work on ubuntu 17.xx/18.xx with virtualbox 5.2.x and 6.0.x
And it looks like similar issue happens in latest Arch Linux
https://superuser.com/questions/1390130/virtualbox-error-ns-error-factory-not-registered-after-linux-4-20-and-vbox-6
So to me it seems like there is issue in latest linux kernel but I'm not sure.

And I have tested this with latest minidcos Release 2019.04.18.2 on ubuntu 16.04 and virtualbox 6.0.4 and it is working fine. So definitely there is some changes in linux kernel that is causing this problem.
