How to install Ruby 1.9.3 on Ubuntu 12.04

The latest and greatest version of Ruby - 1.9.3 - is in the Ubuntu repos. All you need to do is to grab it from there.

So, if you don't have any other version of Ruby installed on the system, just do the following:

sudo apt-get update

sudo apt-get install ruby1.9.1 ruby1.9.1-dev \ rubygems1.9.1 irb1.9.1 ri1.9.1 rdoc1.9.1 \ build-essential libopenssl-ruby1.9.1 libssl-dev zlib1g-dev

After Ruby is installed, check the version of the programming language - run in terminal:
ruby --version
