The Source

The focus of this week has been preparing for our trip to Brussels where we’ll be spending 3 days all working together on LXD before attending and presenting at FOSDEM. @brauner is making good progress on preparing for the liblxc 3.0 release, moving all the various language bindings and tools out of the main tree

The Snapcraft Summit, taking place in Seattle from January 29th to February 2nd, is a forward-thinking five day software hackathon being attended by major software vendors and snap developers working to move the industry forward with software delivery. In the style introduced by the famous BarCamps of old, the agenda is totally free-form

Machine containers, like LXD, proliferate in the datacenters: they provide a native control plane for OpenStack and a lightweight hypervisor for its tenants. LXD optimizes resource allocation and utilization for Kubernetes clusters, modernizes workload management in HPC infrastructure and streamlines lift and shift for legacy applications

Bionic Beaver, the codename for the next Ubuntu LTS release, is due in April 2018 and will ship with both the traditional Xorg graphics stack as well as the newer Wayland based stack, but Xorg will be the default. 17.10, released in October 2017, ships with the Wayland based graphics server as the default and

As details of the Meltdown and Spectre vulnerabilities1 have become clearer a number of statements have been published by the multiple vendors affected; Canonical has issued advisories and updates on fixes and mitigations, the latest of which includes a first round of Spectre mitigations. However, most of these statements focus on the mec

January 09 through January 23 The Kernel Team is completely focused on addressing any Spectre and Meltdown issues as they arise. A secure Ubuntu is our top priority. No new Livepatches are being produced and our regular SRU cycles are suspended while we address Spectre and Meltdown. Spectre mitigation kernels are available. The kernels i

Introduction Nothing too major happened this past week. Part of the time was at an internal planning meeting and the rest have been working on clustering, preparation for 3.0 and fixing a variety of bugs. Next week the entire LXD team will be traveling to Brussels to attend a small team sprint followed by FOSDEM!

  The purpose of this communication is to provide a status update and highlights for any interesting subjects from the Ubuntu Server Team. If you would like to reach the server team, you can find us at the #ubuntu-server channel on Freenode. Alternatively, you can sign up and use the Ubuntu Server Team mailing list.

Here’s an update on what we’ve been working on over the last couple of weeks: GNOME We’ve been working on a patch for udisks to hide snaps from applications such as GNOME’s Disks.  This will hide all loop devices, including installed snaps, from disk management utilities making it less confusing and less cluttered.  We’ve reworked

This is the second blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we walked through all the hardware necessary to follow this series, and introduced Ubuntu Core, the operating system for IoT devices. We installed it on our Raspberry Pi, and used it to

Bullet-proof continuous delivery of software is crucial to the health of your community, more than a way to run manual tests, it also enables your early adopters to test code and give feedback on it as soon as it lands. You may be already using build.snapcraft.io to do so for snaps, but in some cases,

The digital workspace will now be available to all Linux users London, UK – 18th January 2018 – Canonical, the company behind Ubuntu, today announced the first iteration of Slack as a snap, bringing collaboration to open source users. Slack is an enterprise software platform that allows teams and businesses of all sizes to communicate eff

  Introduction The main highlight for this week was the inclusion of the new proxy device in LXD, thanks to the hard work of some University of Texas students! The rest of the time was spent fixing a number of bugs, working on various bits of kernel work, getting the upcoming clustering work to go

This article originally appeared on Kevin Monroe’s blog Keeping an eye on logs and metrics is a necessary evil for cluster admins. The benefits are clear: metrics help you set reasonable performance goals, while log analysis can uncover issues that impact your workloads. The hard part, however, is getting a slew of applications to work

On Tuesday, January 9, 2018 we released Ubuntu kernel updates for mitigation of CVE-2017-5754 (aka Meltdown / Variant 3) for the x86-64 architecture. Releases were made for the following supported Ubuntu series: 12.04 ESM Precise (kernel v3.2) 14.04 LTS Trusty (kernel v3.13) 16.04 LTS Xenial (kernel v4.4) 17.10 Artful (kernel v4.13) Optim
