As you may know, Canonical has created a special Ubuntu Snappy Core image for the Raspberry Pi 2 ARM mini computer, to help the users familiarize with Ubuntu for the Internet of Things OS.
The Snappy Ubuntu Core has been updated a lot lately, adding fixes for node-snapper, a tutorial for node-to-snap, enhanced chatroom snap, and the Snappy Tools PPA has been updated with the latest .snap packages.
The latest changes have been implemented in the Snappy Ubuntu Core Image for Raspberry Pi 2 also, and it can be downloaded from people.canonical.com/~platform/snappy/raspberrypi2/.
If you are an Ubuntu enthusiast and want to help the developers, you can install and test Ubuntu Snappy Core on your Raspberry Pi 2 and report the bugs you find.
