Which version of ubuntu are you running? I am running 11.04 and Ruby 1.9.1 is available in Synaptic package manager. – yasouser Aug 14 '11 at 15:08

I use Ubuntu, and I've found the easiest way to install newer versions of Ruby is to use rvm.
The instructions are here: https://rvm.io/rvm/install/
Basically, it installs different versions of Ruby locally for the user and updates environment variables for Ruby and gems based on which version you decide to use.
It's this easy:
jim@schubert:~$ rvm use system
Now using system ruby.
jim@schubert:~$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]
jim@schubert:~$ gem -v
1.3.7
jim@schubert:~$ rvm use 1.9.2
Using /home/jim/.rvm/gems/ruby-1.9.2-p180
jim@schubert:~$ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
jim@schubert:~$ gem -v
1.5.2
jim@schubert:~$

I don't like having RVM on production server, so I usually install ruby from source with an install script like this:
#!/bin/bash
tmp_dir="/tmp"
version="2.2.3"
minor_version="2.2"
ruby_version="ruby-$version"
echo "*******************"
echo "* Installing Ruby *"
echo "*******************"
sudo apt-get install -y autoconf build-essential libreadline-dev libssl-dev libyaml-dev zlib1g-dev libffi-dev
mkdir -p "$tmp_dir"
cd "$tmp_dir"
wget "http://cache.ruby-lang.org/pub/ruby/$minor_version/$ruby_version.tar.gz"
tar -xvzf $ruby_version.tar.gz
cd $ruby_version
./configure --disable-install-doc
make --jobs `nproc`
sudo make install
cd ..
rm $ruby_version.tar.gz
rm -rf $ruby_version
echo "*******************"
echo "* Ruby installed! *"
echo "*******************"

Since the original question was about the latest version, here is how to get Ruby 2.2.
apt-add-repository ppa:brightbox/ruby-ng
apt-get update
apt-get install ruby2.2
Here is how to get Ruby 2.3.
apt-get install ruby2.3 ruby2.3-dev
Info on brightbox's maintainance of these.

Using sudo apt-get install ruby-full you will get
old version of ruby (1.9) currently existing in Ubuntu repos.
You might want to check installation from source
Download ruby tar from here and then run:
$ tar -xf ruby-X.X.X.tar.gz
$ cd ruby-X.X.X
$ ./configure
$ make
$ sudo make install
In some cases you will need to realod bash by typing:
$ bash

I might came late but this is a very useful website that provides Ubuntu packages and it seems to be maintained and up-to-date. Look here.

Exactly what I wanted! Thank you! Note that `apt` may not install the *latest* Ruby version automatically, because the `brightbox.com` repository may specify an earlier version as preferred. For example, if `apt install ruby` installs `ruby2.3` but you want 2.4, be explicit, e.g., `apt install ruby2.4`. – Ben Johnson Nov 28 '17 at 14:56

It depends on what Ubuntu version you are running, you can get the ruby packages with this link http://packages.ubuntu.com/search?keywords=ruby1.9.1&searchon=names&suite=all§ion=all, to get the latest Ruby(1.9.2-p290) installed, you have to upgrade your Ubuntu to oneiric, if you don't like to upgrade your system, maybe you have to install Ruby with RVM as fl00r answered.
