I had this problem starting the vagrant box (Using git as Terminal, https://git-scm.com/download/win):
$ vagrant box add ubuntu/trusty64
The box 'ubuntu/trusty64' could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp's Vagrant Cloud, 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://vagrantcloud.com/ubuntu/trusty64"]
Error: schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.
The problem was my anti virus (Kaspersky) that was preventing me from adding the box.
I deactivated the anti virus and the command worked:
$ vagrant box add ubuntu/trusty64
$ vagrant init ubuntu/trusty64
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
