As you may know, Canonical has created Snapcraft, an open-source tool that helps the users to package deb packages to the snappy format.
While still under development, Snapcraft 2.38 has been released, bringing a lot of changes and fixes.
Installation instructions:
Canonical has placed Snapcraft in its own PPA, to permit the developers to easily install the software on Ubuntu 16.10 Yakkety Yak, Ubuntu 16.04 Xenial Xerus, Ubuntu 14.04 Trusty Tahr, Linux Mint 18.x, Linux Mint 17.x, Elementary OS 0.3 Freya, Elementary OS 0.4 Loki and other Ubuntu derivative systems.
So, all you need to do is add the PPA to your system, update the local repository index and install the snapcraft package:
$ sudo add-apt-repository ppa:snappy-dev/tools
$ sudo apt-get update
$ sudo apt-get install snapcraft
Or, if you want to install the development version of snapcraft on the same Ubuntu and derivative systems, you need to use another PPA:
$ sudo add-apt-repository ppa:snappy-dev/tools-proposed
$ sudo apt-get update
$ sudo apt-get install snapcraft
Optional, to remove either the stable of the development version of snapcraft, do:
$ sudo apt-get remove snapcraft
