Ubuntu 17.10 Artful Aardvark is ready for download

Canonical has announced the general availability of Ubuntu 17.10 Artful Aardvark. The first thing you’ll notice is the the updated user interface. It’s largely the same as a traditional GNOME desktop, but features a dock which can be moved to the left, bottom, or right of the screen. It can be set up to seem more familiar to Windows users than the Unity desktop ever did.
The new desktop features the latest version of GNOME with some extensions bolted on top – for example, the new dock is one such extension. These extensions were built in collaboration with the GNOME Shell team in order to provide a familiar experience for existing users.
Another big change with this release is that it’s the first to ship with Wayland. The move could be the watershed moment for the Wayland display server. The X display stack will be relegated to an alternative option but won’t be the default.
If you want to give it a go, just head over to Ubuntu.com and downloading the distribution will be clear enough from there.

Samsung unveils ‘Linux on Galaxy’ for DeX — run Fedora and Ubuntu on your Note8?

For whatever reason, people seem to forget that Android is Linux. Remember, folks, Linux is just a kernel — not an operating system. Actually, Android is the world’s most popular such distribution. Even the father of Windows, Mr. Bill Gates, now runs his life from Linux by way of Android.
That’s why Samsung’s new “Linux on Galaxy” — which it unveiled today — is sort of maddening. Don’t get me wrong, the possibility of running a desktop Linux distro using your phone’s hardware is amazing, but Samsung smartphones are already running Linux! In other words, the name of the project is sort of a misnomer that could confuse consumers, but I digress.
“Installed as an app, Linux on Galaxy gives smartphones the capability to run multiple operating systems, enabling developers to work with their preferred Linux-based distributions on their mobile devices. Whenever they need to use a function that is not available on the smartphone OS, users can simply switch to the app and run any program they need to in a Linux OS environment,” says Samsung. Here’s the deal, folks — there aren’t many details on what “Linux on Galaxy” exactly is. Since Galaxy phones use ARM processors, will it be running ARM-compiled distros, or will it emulate x86_64? Maybe the desktop Linux distro will just be a virtual machine running on a server remotely. After all, that is how Samsung makes Windows “run” on DeX today.

Ubuntu 17.10 releases with GNOME, Kubernetes 1.8 & minimal base images

19th October, London, UK: Canonical today announced the release of Ubuntu 17.10 featuring a new GNOME desktop on Wayland, and new versions of KDE, MATE and Budgie to suit a wide range of tastes. On the cloud, 17.10 brings Kubernetes 1.8 for hyper-elastic container operations, and minimal base images for containers. This is the 27th release of Ubuntu, the world’s most widely used Linux, and forms the baseline for features in the upcoming Long Term Support enterprise-class release in April 2018.

“Ubuntu 17.10 is a milestone in our mission to enable developers across the cloud and the Internet of Things” said Mark Shuttleworth, CEO and Founder of Canonical. “With the latest capabilities in Linux, it provides a preview of the next major LTS and a new generation of operations for AI, container-based applications and edge computing.”

Enhanced security and productivity for developers

The Atom editor and Microsoft Visual Studio Code are emerging as the new wave of popular development tools, and both are available across all supported releases of Ubuntu including 16.04 LTS and 17.10.

The new default desktop features the latest version of GNOME with extensions developed in collaboration with the GNOME Shell team to provide a familiar experience to long-standing Ubuntu users. 17.10 will run Wayland as the default display server on compatible hardware, with the option of Xorg where required.

Connecting to WiFi in public areas is simplified with support for captive portals. Firefox 56 and Thunderbird 52 both come as standard together with the latest LibreOffice 5.4.1 suite. Ubuntu 17.10 supports driverless printing with IPP Everywhere, Apple AirPrint, Mopria, and WiFi Direct. This release enables simple switching between built-in audio devices and Bluetooth.

Secure app distribution with snaps

In the 6 months since April 2017, the number of snaps has doubled with over 2000 now available for Ubuntu, Debian, Solus and other Linux distributions. Snaps are a single delivery and update mechanism for an application across multiple Linux releases, and improve security by confining the app to its own set of data. Hiri, Wavebox, and the Heroku CLI are notable snaps published during this cycle.

Ubuntu 17.10 features platform snaps for GNOME and KDE which enable developers to build and distribute smaller snaps with shared common libraries. Delta updates already ensure that snap updates are generally faster, use less bandwidth, and are more reliable than updates to traditional deb packages in Ubuntu.

The catkin Snapcraft plugin enables Robot Operating System (ROS) snaps for secure, easily updated robots and drones. There are many new mediated secure interfaces available to snap developers, including the ability to use Amazon Greengrass and Password Manager.

The latest hardware support and container capabilities

Ubuntu 17.10 ships with the 4.13 based Linux kernel, enabling the latest hardware and peripherals from ARM, IBM, Dell, Intel, and others. The 17.10 kernel adds support for OPAL disk drives and numerous improvements to disk I/O. Namespaced file capabilities and Linux Security Module stacking reinforce Ubuntu’s leadership in container capabilities for cloud and bare-metal Kubernetes, Docker and LXD operations.

Canonical’s Distribution of Kubernetes, CDK, supports the latest 1.8 series of Kubernetes. In addition to supporting the new features of Kubernetes 1.8, CDK also enables native cloud integration with AWS, native deployment and operations on VMWare, Canal as an additional networking choice, and support for the IBM zSeries mainframe.

Netplan by default

Network configuration has over the years become fragmented between NetworkManager, ifupdown and other tools. 17.10 introduces netplan as the standard declarative YAML syntax for configuring interfaces in Ubuntu. Netplan is backwards compatible, enabling interfaces to continue to be managed by tools like NetworkManager, while providing a simple overview of the entire system in a single place. New installations of Ubuntu 17.10 will use Netplan to drive systemd-networkd and NetworkManager. Desktop users will see their system fully managed by NetworkManager as in previous releases. On Ubuntu server and in the cloud, users now have their network devices assigned to systemd-networkd in netplan. Ifupdown remains supported; upgrades will continue to use ifupdown and it can be installed for new machines as needed.

Linux kernel community tries to castrate GPL copyright troll

Linux kernel maintainer Greg Kroah-Hartman and several other senior Linux figures have published a “Linux Kernel Community Enforcement Statement” to be included in future Linux documentation, in order to ensure contributions to the kernel don’t fall foul of copyright claims that have already seen a single developer win “at least a few million Euros.”
In a post released on Monday, October 16th, Kroah-Hartman explained the Statement’s needed because not everyone who contributes to the kernel understands the obligations the GNU Public Licence 2.0 (GPL 2.0), and the licence has “ambiguities … that no one in our community has ever considered part of compliance.”
Those ambiguities, he writes, have been used by a developer named Patrick McHardy to run multiple copyright enforcement lawsuits.
McHardy is a former contributor to a project called Netfilter that brings useful networking functionality such as network address translation to Linux. However the project suspended him from its core team in 2016 over “license enforcement activities” that contravened the project’s own policies. He’s also been criticised by the Software Freedom Conservancy for “prioritizing financial gain over compliance.”
Lawyer Heather Meeker believes that McHardy wrote “well under .25% of the code in the kernel” but has parlayed that into around 50 copyright complaints about Linux companies’ use of Netfilter. Most of his actions take place in Germany, where local law makes such claims easier to mount.

System76 ‘Lemur’ and ‘Galago Pro’ Ubuntu Linux laptops get 8th gen Intel Core CPUs

Earlier today, Microsoft unveiled the all-new Surface Book 2. People all over the world are probably very excited about the device. Oh, what? You aren’t excited? You mean, you don’t want a super-expensive non-upgradeable Windows 10 tablet that plugs into a keyboard? What a shocker! All joking aside, that is very understandable. After all, most consumers would be better served by a traditional laptop.
If you don’t want a gimmicky Windows 10 tablet, a laptop running a Linux-based operating system, such as Ubuntu, is a wise alternative. System76 is one of the best sellers of these types of notebooks, and today, two of its most popular models are getting huge upgrades. You see, both the Lemur and Galago Pro laptops now have 8th generation ‘Coffee Lake’ Intel Core CPU options.
New processors aside, these laptops should be pretty much identical to prior generations — which is a very good thing. If you want to configure a Lemur with a Coffee Lake chip, you can build your own.
Keep in mind, while the laptops are still shipping with vanilla Ubuntu, that will change in the near future. System76 will soon begin offering its own Ubuntu-based Pop_OS! operating system by default.

This is a guest post by Michael Iatrou

OpenStack is the dominant solution in the IaaS space, fueled by the need for reliable, scalable and interoperable private cloud infrastructure to accommodate cloud native applications. Through OpenStack’s open APIs, tenants can easily deploy elaborate virtual (overlay) networks, integrate with a variety of storage backends, even leverage modern hypervisor-like machine containers (LXD) for bare metal performance. Although the tooling allows a full fledged OpenStack deployment on just a single machine, the intrinsic efficiencies that OpenStack’s design promises, materialize at a certain scale — typically at least 12 servers.

There is a large number of environments which would benefit from the merits of virtualization, including but not limited to hydrocarbon exploration sites, diagnostic imaging for health centers, backoffice for restaurants and retail store IT operations. But their per location server footprint is very small, usually no more than a handful of machines. We will explore here how to use the same tooling that delivers operational efficiency for large OpenStack and Kubernetes deployments, in order to revamp small scale environments.

MAAS stands for Metal As A Service and enables you to treat physical servers like an elastic cloud-like resource. As of MAAS 2.2 “pod” is introduced as an operational concept. A MAAS pod effectively describes the availability of resources and enables the creation (or composition) of machines with a set of those resources. A user can allocate the needed CPU, RAM, and (local or remote) storage resources manually (using the MAAS UI or CLI) or dynamically (using Juju or the MAAS API). That is, machines can be allocated "just in time", based on CPU, RAM, and storage constraints of a specific workload. MAAS 2.2. supports two types of pods, (1) Physical systems with Intel RSD and (2) Virtual Machines with KVM (using the virsh interface).

We have published a detailed tutorial with step by step instructions on how to install and configure a testbed environment for MAAS KVM pods. You can quickly transformed a physical server into a lightweight, reliable virtual machine management node. You can even test it on your laptop.

MAAS has been designed to be a modern, agile machine provisioning and infrastructure modelling solution, enabling both physical and virtual infrastructure. Beyond MAAS’ extensive adoption in cloud native environments, it can optimize the utilisation of existing in-house, small scale IT infrastructure using VM pods. The pod abstraction is very powerful and flexible, and it has quickly gained attention, with many new features coming soon! Try it out!

Top snaps in September: games, GNOME apps and more!

October, it’s almost time for a new Ubuntu release! This month’s pick of the top snaps is all about spending relaxing time with your computer: playing games, listening to music and enjoying beautiful GNOME applications!

If the term snaps doesn’t ring a bell, they are a new way for developers to package their apps, bringing many advantages over traditional package formats such as .deb, .rpm, and others. They are secure, isolated and allow apps to be rolled back should an issue occur. They also aim to work on any distribution or platform, from IoT devices to servers, desktops and mobile devices. Snaps really are the future of Linux application packaging and we’re excited to showcase some great examples of these each month.

Ubuntu, Debian, Fedora and elementary OS All Patched Against WPA2 KRACK Bug

As you are aware, there’s a major WPA2 (Wi-Fi Protected Access II) security vulnerability in the wild, affecting virtually any device or operating system that uses the security protocol, including all GNU/Linux distributions.
Security researcher Mathy Vanhoef was the one to discover the WPA2 bug, which affects the wpa_supplicant and hostapd packages on Linux-based operating systems, allowing a remote attacker to obtain sensitive information like credit card numbers, passwords, usernames, etc. with key reinstallation attacks (a.k.a. KRACK).
Canonical announced that it patched the security issue in the Ubuntu 17.04 (Zesty Zapus), Ubuntu 16.04 LTS (Xenial Xerus), and Ubuntu 14.04 LTS (Trusty Tahr) releases, as well as all official derivatives, including Kubuntu, Xubuntu, Lubuntu, Ubuntu MATE, Ubuntu Budgie, Ubuntu Kylin, and Ubuntu Studio.
In their security notice, Canonical notes the fact that two other security vulnerabilities were patched, both discovered by Imre Rad.
Run updates and restart ASAP! A major security update was issued that affects anyone using Wifi.
