If you find that vagrant box list somehow does not contain a box you previously had, you can sometimes add the box back if you still have the sources for it in ~/.vagrant.d/boxes.
$ cd ~/.vagrant.d/boxes/precise64/0/virtualbox/
$ tar czf ~/precise64.box .
$ vagrant box add precise64 ~/precise64.box
Downloading box from URL: file:/Users/ryanuber/precise64.box

Successfully added box 'precise64' with provider 'virtualbox'!
Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.
The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows
the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.
Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to
a specific version, you will need to compile it yourself. Then asdf is your best friend.

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.
As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).
For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:
| # -*- mode: ruby -*- | |
| # vi: set ft=ruby : | |
| Vagrant.configure(2) do |config| | |
| config.vm.box = 'ubuntu/trusty64' | |
| config.vm.provision 'shell', path: 'install-python' | |
| end |
| #!/bin/sh | |
| KERNEL=$1 | |
| PATCHVER=$2 | |
| [ -z "$1" -o -z "$2" ] && { | |
| echo "usage: refresh_kernel.sh <version> <release>" | |
| echo "example: refresh_kernel.sh 3.18 3.18.30" | |
| exit 1 | |
