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 1.0 has been released, bringing bug-fixes only.
Installation instructions:
Canonical has placed Snapcraft in its own PPA, to permit the developers to easily install the software on Ubuntu 15.10 Wily Werewolf, Ubuntu 14.04 Trusty Tahr and derivative systems like Linux Mint 17.x, Elementary OS 0.3 Freya 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 15.10, Ubuntu 15.04, Ubuntu 14.04, Linux Mint 17.x and Elementary OS 0.3 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
