It looks like it might be related to the provider using an older version of Terraform: https://github.com/terra-farm/terraform-provider-virtualbox/blob/c4fcdba845e54a69638f7d6ba34037caf8b6246f/go.mod#L8

This would be part of #50 to get it fixed.

@basictheprogram You also are using both url and image, these two fields have been merged. Please take a look at the README. It would turn into

image = "https://vagrantcloud.com/ubuntu/boxes/xenial64/versions/20180420.0.0/providers/virtualbox.box"

This is probably not related, just a FYI.

@basictheprogram we have released a TF 0.12 compatible version. You can download it here:
