This was a vagrant script I fiddled with for way too long. Also discussed here: https://talk.jekyllrb.com/t/install-problem-with-rbenv/3068/3 It's kind of working, but for the automation of starting the server at the end there.

But the ultimate thing which took me way too long to realise, is that while there's lots of rbenv advice out there, life is far easier if ubuntu packages are available with the ruby version you want, which (and I failed to understand this initially) you get if you're on a later version of ubuntu. Easy with vagrant. Just start from a different base box. With a 'xenial32' base box you can just install a 'ruby2.3' ubuntu package! Job done. Alternatively use "ppa packages". I'm told http://ppa.launchpad.net/brightbox/ruby-ng/ubuntu is the normal solution on older ubuntus
