For the same reasons that Flatpak is not available for Ubuntu 14.04, it
becomes harder and harder to backport new native packages to stale
releases, whether they have hit EOL or not. Supported until 2019 only
applies to the Ubuntu main repository, everything else is optional.

I do hope that Flatpak and Snap will make this backporting problem
obsolete for most users, but users do have to first be on a stable
platform that supports Flatpak (GLib 2.44, released March 2015).

It cannot access system libraries installed in /usr or /usr/local by
design, but it can access anything in your home directory.

I'm not entirely sure if the Flatpak developers have a plan to deal with
applications that are extendable or pluggable requiring additional
libraries.

Network sockets are shared with the host so Octave can communicate with
native local services and applications.
