Install ub14jan.ova inside VirtualBox on your laptop.

If you really want to use Ubunutu 14, this is easy.

I clicked on the terminal icon and entered shell commands:

sudo apt update
sudo apt upgrade

Eventually the last command finished and then I rebooted the instance.

After bootup and login, the machine asked me:

A new version of Ubuntu is available. Would you like to upgrade?

I answered: Ask Me Later

I issued more shell commands:


sudo apt-get install autoconf bison build-essential libssl-dev libyaml-dev \
libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3       \
libgdbm-dev libsqlite3-dev gitk postgresql postgresql-server-dev-all  \
libpq-dev emacs wget curl chromium-browser openssh-server aptitude    \
ruby ruby-dev sqlite3 r-base r-base-dev

Then I rebooted again.

After bootup, I verified that Ruby 2.3.1 was installed with a simple shell command:

ruby -v
