Solution 4 - Ruby
Since this question was answered I have found a new alternative here:
https://www.brightbox.com/docs/ruby/ubuntu/
In short:
# For ubuntu >= 14.04 install software-properties-common
# instead of python-software-properties
sudo apt-get install python-software-properties
sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt-get update
sudo apt-get -y install ruby2.2 ruby-switch
sudo ruby-switch --set ruby2.2
I must say that according to my tests this is faster than the alternatives shown here, because the compiling step is skipped.
Solution 5 - Ruby
I particularly like ruby-install, available here: https://github.com/postmodern/ruby-install
It will install ruby (any version), JRuby, etc., and has many other features besides.
Solution 6 - Ruby
The better way to install ruby on ubuntu without RVM is to install it with rbenv in terminal as follows:
$ sudo apt-get update
Install the rbenv and Ruby dependencies with apt-get:
$ sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Now run these commands as follows:
$ cd
$ git clone https://github.com/rbenv/rbenv.git ~/.rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc
$ exec $SHELL
$ git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
$ echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
$ exec $SHELL
Time to install ruby:
$ rbenv install 2.3.3
which ever is the latest and stable version
$ rbenv global 2.3.3
To check the version
$ ruby -v
To disable the local documentation, as this process can be lengthy:
$ echo "gem: --no-document" > ~/.gemrc
Install the bundler gem, to manage your application dependencies:
$ gem install bundler
