Trying to upgrade to ubuntu/xenial64

[estribiyo]

I've been trying to upgrade to Ubuntu Xenial 64, because of SSL error on Python <2.7.9 because I figured that is the straight way... instead of installing Python 2.7.9 on Ubuntu Trusty 64.

The matter is that ubuntu/xenial64 comes with NO Python at all...

What do you think would be the best solution? I'm newbie to Vagrant but my tries include:

Trying to install it via ansible-install-roles.sh, but the problem is the lack of Python, that causes ansible-galaxy cannot run.

Include a line in Vagrantfile:
config.vm.provision "shell", inline: "sudo apt-get update && sudo apt-get install -y python"
but this solution needs to run before ansible-install-roles.sh then run it and after all, run again vagrant provision.

Many thanks!
