I've been trying to start a new box from an existing repo:
$ vagrant box add ubuntu/trusty64
==> box: Loading metadata for box 'ubuntu/trusty64'
==> box: Adding box 'ubuntu/trusty64' (v20160303.0.0) for provider: virtualbox
An error occurred while downloading the remote file. The error
message, if any, is reproduced below. Please fix this error and try
again. The requested URL returned error: 404 Not Found
Is there anyway to download a previous version of a box?
Thanks
