14 DAY TRIAL // Just one week after announcing the availability of the first Release Candidate (RC) build of the upcoming Ubuntu Snappy Core 16 operating system, Snappy developer Michael Vogt informed us about the release of the RC2 milestone.
That's right, Ubuntu Snappy Core 16 Release Candidate 2 is now available for download, supporting Raspberry Pi 2, Raspberry Pi 3, DragonBoard 410c, as well as 64-bit (amd64) and 32-bit (i386) PCs, and it looks like it adds various fixes to improve Raspberry Pi and DragonBoard support.
"Ubuntu Core is an operating system entirely based on snaps, including its foundation. Applications, kernel, core operating system, and gadget components are all managed as snaps and are installed and refreshed by snapd, the daemon and tooling responsible for making it all dance," said Michael Vogt in the release announcement.
Here's how to test the new Ubuntu Snappy Core 16 builds
If you're willing to take the second Release Candidate images of the Ubuntu Snappy Core 16 operating system for a test drive, you should know that the 64- and 32-bit PC images are bootable on real hardware, as well as in VirtualBox and QEMU-KVM virtualization solutions.
On the other hand, those of you who want to test the new Ubuntu Snappy Core 16 builds on Raspberry Pi 3, Raspberry Pi 2, or DragonBoard 410c single-board computers should first deploy the images on an SD card using the commands listed below in a terminal emulator by replacing "dev/sdXX" with the location of the SD card (e.g. /dev/sdc).
sudo snap install --devmode --beta godd
sudo /snap/bin/godd ubuntu-core-16-pi2.img.xz [this will print a message showing what devices are removable]
xzcat ubuntu-core-16-pi2-rc2.img.xz | sudo /snap/bin/godd - /dev/sdXX
