Debian provisioning failed: no sudo

Problem

Vagrant will install rsync after a VM booted but it failed because debian 8 image on Vultr don't have sudo command.

... after booted the VM and vagrant detected it is debian

==> default: Installing rsync to the VM...

how to solve

vagrant-digitalocean had same issue but it solved, so we can fix same ways. However, I think this issue may also be fixed improving provisioning code in Vagrant... How do you think?

Anyway, I try dealing with this issue next weekend.

I no longer actively maintain this plugin, so if you'd like to become a maintainer and fix this (along with few other unresolved issues), I'm more than happy to give you full access.
