Vagrant issue with Ubuntu16.04

While executing the command "vagrant up" you will see the following error message.

 Box 'generic/ubuntu2004' could not be found. Attempting to find and install...

   servername: Box Provider: virtualbox

   servername: Box Version: 3.3.0

The box 'generic/ubuntu2004' could not be found or

could not be accessed in the remote catalog. If this is a private

box on HashiCorp's Atlas, please verify you're logged in via

`vagrant login`. Also, please double-check the name. The expanded

URL and error message are shown below:

URL: ["https://atlas.hashicorp.com/generic/ubuntu2004"]

Error: The requested URL returned error: 404 Not Found

So the issue is with your vagrant version (1.8.7), so here we would require the last Vagrant version 2

On your Ubuntu 16.04LTS vagrant binay download will show the following error.
