We've provisioned a Virtual Box VM, are able to "vagrant halt", "vagrant up" and "vagrant ssh", no problems.
Next, installed docker-ce in the guest.
vagrant halt, vagrant up, we get this: The configured shell (config.ssh.shell) is invalid and unable to properly execute commands.
We've been using this VM for a couple of years now, looking to determined what has changed.
The docker version is a bit older, docker-ce-17.09.1.ce-1.el7.centos
Next step, upgrade docker in the VM, docker-ce-18.09.5-3.el7.x86_64
