Ubuntu Core provides transactional updates with rigorous application isolation. This is the smallest, safest Ubuntu ever, on devices and on the cloud. We’re excited to unleash a new wave of developer innovation with snappy Ubuntu Core! ” - Mark Shuttleworth, founder of Ubuntu and Canonical.
So we decided to try the new system to use the advantages of the snappy package system and give you the possibility to play with Ubuntu Core and guh on you Beaglebone Black or Raspberry Pi 2. You can find a good documentation of the new operating system from Canonical Ubuntu Core.
Currently we provide a guhIO snappy package only armhf, but we have planned to change that soon. If you want to install guhIO on you device you can do following:
First you need to add the PPA file:
$ sudo add-apt-repository ppa:snappy-dev/tools
Now you can install the snappy-tools
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install snappy-tools bzr
If you want to install Ubuntu Core on your device, you can follow the official instruction or use this one.
