Ubuntu Core 16 Release Candidate 2 (with Pi and more)

Hi, The Snappy team is happy to announce the second Release Candidate of Ubuntu Core 16. 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. Since the previous release: - Several small bugfixes - Fixes for the pi2/pi3/dragonboard The images are available currently for PC (amd64, i386) and for Pi2/Pi3 and Dragonboard: http://cdimage.ubuntu.com/ubuntu-core/xenial/daily-preinstalled/current Once unpacked, the images are bootable, the PC image can be booted directly in qemu-kvm, virtualbox or on real hardware. When running the images in qemu-kvm it is helpful to use the "-redir" feature of qemu-kvm. E.g.: $ kvm -smp 2 -m 1500 -redir tcp:10022::22 ubuntu-core-16-amd64-rc2.img The message from console-conf is a bit misleading in this setup. It will say "ssh USER at 10.0.2.15". However due to the way that qemu-kvm user networking behaves, you will actually have to run the following to ssh into the images: $ ssh -p 10022 USER at localhost or if you have the following snippet in ~/.ssh/config Host kvm.snappy Hostname localhost Port 10022 User USER UserKnownHostsFile /dev/null StrictHostKeyChecking no then you can just $ ssh kvm.snappy The pi2/pi3/dragonboard image can be written to a sdcard via dd. An alternative way to write the image is to use "go-dd": $ 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 After booting the image you can enter your Ubuntu One email and it will automatically create a matching user with the right ssh keys. If you do not have an Ubuntu SSO account yet you can create one at: https://login.ubuntu.com/ (don't forget to add your public ssh keys to that account). Known issues: - pi3 wlan can not be initially configured, wired network needs to be used for the initial setup (you can re-run "sudo console-conf" at any later point to re-configure the device for wlan only operation). These images follow the "candidate" channel. If you find any issues, please let us know via: https://bugs.launchpad.net/snappy/ Enjoy the fresh images!
