Canonical holds Ubuntu to the highest standards of security and quality.  This week we published candidate Ubuntu kernels providing mitigation for CVE-2017-5715 and CVE-2017-5753 (ie, Spectre / Variants 1 & 2) to their respective -proposed pockets for Ubuntu 17.10 (Artful), 16.04 LTS (Xenial), and 14.04 LTS (Trusty).  We have also expande

Canonical and Microsoft have teamed up to deliver an truly special experience — running Ubuntu containers with Hyper-V Isolation on Windows 10 and Windows Servers! We have published a fantastic tutorial at https://ubu.one/UhyperV, with screenshots and easy-to-follow instructions.  You should be up and running in minutes! Follow that tutor

Back in March, we asked the HackerNews community, “What do you want to see in Ubuntu 17.10?”: https://ubu.one/AskHNA passionate discussion ensued, the results of which are distilled into this post: http://ubu.one/thankHNIn fact, you can check that link, http://ubu.one/thankHN and see our progress so far this cycle.  We already have a beta

Just another reason why LXD is so awesome…You can easily configure your own cloud-init configuration into your LXD instance profile.In my case, I want cloud-init to automatically ssh-import-id kirkland, to fetch my keys from Launchpad.  Alternat

Yesterday, I delivered a talk to a lively audience at ContainerWorld in Santa Clara, California.If I measured “the most interesting slides” by counting “the number of people who took a picture of the slide”, then by far “the most interesting slides” ar

From Linux kernel livepatches to encryption to ASLR to compiler optimizations and configuration hardening, we strive to ensure that Ubuntu 16.04 LTS is the most secure Linux distribution out of the box.These slides try to briefly explain:what we do to

If you haven’t heard about last week’s Dirty COW vulnerability, I hope all of your Linux systems are automatically patching themselves…Why?  Because every single Linux-based phone, router, modem, tablet, desktop, PC, server, virtual machine, and absolutely everything in between — including all versions of Ubuntu since 2007 — was vulnerabl

I hope you’ll enjoy a shiny new 6-part blog series I recently published at Linux.com.The first article is a bit of back story, perhaps a behind-the-scenes look at the motivations, timelines, and some of the work performed between Microsoft and Canonica

I had the honor and privilege a couple of weeks ago, to participate in a recording of The Changelog, a podcast dedicated to Open Source technology.You can listen to it here.These guys — Jerod and Adam — produce a fantastic show, and we covered a lot

If you have long-running Ubuntu systems (server or desktop), and you keep those systems up to date, you will, over time, accumulate a lot of Linux kernels.Canonical’s Ubuntu Kernel Team regularly (about once a month) provides kernel updates, patching s

Below you can find the audio/video recording of my OpenStack Austin presentation, where I demonstrated Ubuntu OpenStack Mitaka, running on top of Ubuntu 16.04 LTS, entirely within LXD machine containers.  You can also download the PDF of the slide
