stdout. This flexibility should make any system administrator or developer
guru happy.
Ubuntu Core
Ubuntu Core adds the absolute minimum of files and code necessary for a
usable Ubuntu server image to it a new means of managing software
packages. The idea is similar to how smart phones like Android-based phones
provide software: The software packages include everything they need to run
on the operating system, effectively making it so that a package is isolated
from the operating system more completely. This is designed to protect
against the possibility of a package breaking other packages or an entire
operating system installation. It is also intended to make updates easier and
cleaner for use cases like cloud deployment or IoT (Internet of things). This
feature first appeared in Ubuntu 16.04 LTS.
Using Snaps
Software bundles that can be packaged using Ubuntu Core are called snaps.
Snaps can be installed using Ubuntu Software or from the command line, as
described in this section.
To show a list of snap packages that are available to be installed, use the
following:

matthew@seymour:~$ snap find
Because snaps are new, few packages are available today. However, the list is
growing and is likely to become unwieldy at some point. Sure, you can use
grep to search through the output to try to find a specific package in the list,
but you can also use this:

matthew@seymour:~$ snap find searchterm
To install a snap package, use the following:
Click here to view code image
matthew@seymour:~$ sudo snap install packagename
To show a list of snap packages that are currently installed, use the following:
