Description of problem:
The latest Vagrant package 2.2.6 provided by the @System repository on Fedora 31 is not compatible with the latest VirtualBox v6.1 package provided by the @System repository. 2.2.6 is only compatible with VirtualBox <=6.0


Version-Release number of selected component (if applicable):
2.2.6


How reproducible:


Steps to Reproduce:
1. Execute 'vagrant init ubuntu/bionic64'
2. Execute 'vagrant up'
3. Execute 'vagrant up --provider virtualbox'

Actual results:
'Vagrant up' fails with an error message
"The box you're attempting to add doesn't support the provider
you requested.

Name: ubuntu/bionic64
Address: https://vagrantcloud.com/ubuntu/bionic64
Requested provider: [:libvirt]"


'Vagrant up --provider virtualbox' provides the error message: 
"The provider 'virtualbox' that was requested to back the machine
'default' is reporting that it isn't usable on this system. The
reason is shown below:

Vagrant has detected that you have a version of VirtualBox installed
that is not supported by this version of Vagrant. Please install one of
the supported versions listed below to use Vagrant:

4.0, 4.1, 4.2, 4.3, 5.0, 5.1, 5.2, 6.0"

Expected results:
Executing 'vagrant up' after 'vagrant init ubuntu/bionic64' should begin to set up a virtual server via VirtualBox using the Vagrantfile created by 'vagrant init'
