I dont know how to install the latest Ruby on Ubuntu.

First I installed the default Ruby 1.9.3, using

sudo apt-get install ruby

Then I tried to install the 2.0 version using

sudo apt-get install ruby2.0

My version of Ruby is still "ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux])"

What should I do?

There is a PPA with up-to-date versions of Ruby 2.x for Ubuntu 12.04+:

$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update
$ sudo apt-get install ruby2.4

$ ruby -v
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux-gnu]
