prisoninmate writes: On Monday, February 22, 2016, Softpedia reported on the availability of new kernel updates for several of Canonical's supported Ubuntu Linux operating systems, including Ubuntu 15.10, for which five kernel vulnerabilities have been patched at that point in time. And from the looks of it, the respective kernel updates introduced a regression, which Canonical patched four days later, on February 26, 2016, saying that the issue was introduced along with the fixed vulnerabilities for Ubuntu 15.10 (Wily Werewolf) and it broke graphics displays for those running the OS in VMWare VMs.

LichtSpektren writes: Phoronix reports that Bradley M. Kuhn and Karen M. Sandler at the Software Freedom Conservancy (SFS) have posted a blog post today arguing that Canonical's plan to distribute Ubuntu 16.04 LTS "Xenial Xerus" with support for the ZFS file system violates the Linux kernel's GPLv2 license.

On February 18, Dustin Kirkland at Canonical wrote on his blog: "We at Canonical have conducted a legal review, including discussion with the industry's leading software freedom legal counsel, of the licenses that apply to the Linux kernel and to ZFS. And in doing so, we have concluded that we are acting within the rights granted and in compliance with their terms of both of those licenses...The CDDL cannot apply to the Linux kernel because zfs.ko is a self-contained file system module — the kernel itself is quite obviously not a derivative work of this new file system. And zfs.ko, as a self-contained file system module, is clearly not a derivative work of the Linux kernel but rather quite obviously a derivative work of OpenZFS and OpenSolaris. Equivalent exceptions have existed for many years, for various other stand alone, self-contained, non-GPL kernel modules. Our conclusion is good for Ubuntu users, good for Linux, and good for all of free and open source software."

The SFS's blog post of today states: "We are sympathetic to Canonical's frustration in this desire to easily support more features for their users. However, as set out below, we have concluded that their distribution of zfs.ko violates the GPL."

While these attacks are regrettable, and part of an infrastructure problem rather than a problem with the distribution itself, it increasingly appears that the Linux Mint team is spread too thin when it comes to security. The distribution itself blacklists updates that work perfectly in Ubuntu and Debian, and the graphical utilities don't update the kernel. Because the value added by Linux Mint is in Cinnamon, why do the developers need to distribute a broken version of Ubuntu when the Cinnamon DE could be distributed as an Ubuntu spin?

But not only Ubuntu 14.04 LTS (Trusty Tahr) users can update, as all the official flavors have been updated as well, so users of Kubuntu 14.04 LTS, Edubuntu 14.04 LTS, Xubuntu 14.04 LTS, Lubuntu 14.04 LTS, Ubuntu Studio 14.04 LTS, Mythbuntu 14.04 LTS, Ubuntu GNOME 14.04 LTS, and Ubuntu Kylin 14.04 LTS can also update their systems today or grab the new ISOs.

LichtSpektren writes: Ubuntu developer Dustin Kirkland has posted on his blog that Canonical plans to officially support the ZFS file system for the next Ubuntu LTS release, 16.04 "Xenial Xerus." The file system, which originates in Solaris UNIX, is renowned for its feature set (Kirkland touts "snapshots, copy-on-write cloning, continuous integrity checking against data corruption, automatic repair, efficient data compression") and its stability. "You'll find zfs.ko automatically built and installed on your Ubuntu systems. No more DKMS-built modules!" N.B. ext4 will still be the default file system due to the unresolved licensing conflict between Linux's GPLv2 and ZFS's CDDL.

Last week you asked questions of Ubuntu Unleashed author Matthew Helmke, about everything from system D to the future of Ubuntu and Canonical; he's responded, at length. Read on for Matthew's answers.

New submitter Tenebrousedge writes: Docker container sizes continue a race to the bottom with a couple of environments weighing in at less than 10MB. Following on the heels of this week's story regarding small images based on Alpine Linux, it appears that the official Docker images will be moving from Debian/Ubuntu to Alpine Linux in the near future. How low will they go?

An anonymous reader writes: Tests were carried out at Phoronix of all Ubuntu Long-Term Support releases from the 6.06 "Dapper Drake" release to 16.04 "Xenial Xerus," looking at the long-term performance of (Ubuntu) Linux using a dual-socket AMD Opteron server. Their benchmarks of Ubuntu's LTS releases over 10 years found that the Radeon graphics performance improved substantially, the disk performance was similar while taking into account the switch from EXT3 to EXT4, and that the CPU performance had overall improved for many workloads thanks to the continued evolution of the GCC compiler.

Matthew Helmke (personal blog) is the author of the newly published 11th edition of Ubuntu Unleashed (published by Pearson); this updated edition of the book will cover the OS through Ubuntu's 15.10 and (forthcoming) 16.04 releases. Helmke is also a former Ubuntu Forum administrator, a musician, an entrepreneur, and a long-time Slashdot reader who now leads a "nice quiet life in Iowa." Ask Matthew about what it's like to be a Linux book author and community leader, and his thoughts on Canonical, the goods and bads of modern Linux distributions, and the future of Ubuntu -- especially relevant with the upcoming release of the first Ubuntu-based tablet. (Remember, Matthew isn't responsible for gripes you may have with either Ubuntu or Canonical, but he might have some good solutions to particular problems.) Ask as many questions as you'd like; we just ask that you keep them on-topic, and please stick to one question per post.

LichtSpektren writes: Several tech sites have now broke the news that Canonical has revealed their BQ Aquaris M10 Ubuntu Tablet. Joey-Elijah Sneddon builds the hype: "A stunning 10.1-inch IPS touch display powered a full HD 1920×1200 pixel resolution at 240 ppi. Inside is a 64-bit MediaTek MT8163A 1.5GHz quad-core processor, 2GB of RAM, and 16GB of internal memory. A micro SD memory card is included, adding storage expansion of up to 64GB. Furthermore, the converged slate includes an 8-megapixel rear camera with autofocus and dual LED flash (and capable of recording in full 1080p), plus a front facing 3-megapixel camera for video chats, vlogs and selfies. Front facing Dolby Atmos speakers will provide a superior sound experience during movie playback. The M10 measure 246mm x 171mm x 8.2mm, weighs just 470 grams — lighter than the Apple iPad Air — and has a 7280 mAh battery to give up to 10 hours of use. ... Tablet mode offers a side stage for running two apps side-by-side, plus a full range of legacy desktop applications, mobile apps and scopes. LibreOffice, Mozilla Firefox, The GIMP and Gedit are among a 'curated collection of legacy apps' to ship pre-installed on the tablet. It will also be possible for developers and enthusiasts to install virtually any ARM compatible app available on Ubuntu using the familiar 'apt-get' command." A photo gallery can also be seen on his website here. The price is not yet announced, but the Android version of the same tablet is currently on sale for €229.

There is Fedora that offers latest from Gnome, but there is no such distro that offers the same level of integration with KDE software; yes, there is openSUSE but it offers KDE as an option. So Kubuntu based KDE Neon is a project to give KDE users and contributors a way to get KDE's desktop software while it's still fresh. It'll be providing packages of the latest KDE software so users can install it and stay up to date on a stable base.

An anonymous reader writes: This article details a Linux user's struggles to submit a grant application when the process requires finicky, proprietary software. It also covers familiar ground made timely by the upcoming elections: the U.S. should prefer open source software and open standards over proprietary alternatives. The grant application required a PDF created by Adobe Acrobat — software Adobe no longer supports for Linux. Once the document was created, attempting to submit it while using Ubuntu fails silently. (On Windows 7, it worked immediately.) The reader argues, "By requiring Acrobat the government gives preference to a particular software vendor, assuring that thousands of people who otherwise would not choose to use Adobe software are forced to install it. Worse, endorsing a proprietary, narrowly supported technology for government data poses the risk that public information could become inaccessible if the vendor decides to stop supporting the software. Last but not least, there are privacy and fairness issues at stake. Acrobat is a totally closed-source program, which means we have to take Adobe's word for it that nothing sketchy is going on in its code. ... It would seem to be in the interest of the public for the government to prefer an open source solution, since it is much harder to hide nefarious features inside code that can be publicly inspected."

An anonymous reader writes: A new report at Phoronix looks at the OpenGL performance of 27 graphics cards from the GeForce 8 through GeForce 900 series. Various Ubuntu OpenGL games were tested on these graphics cards dating back to 2006, focusing on raw performance and power efficiency. From oldest to newest, there was a 72x increase in performance-per-Watt, and a 100x increase in raw performance. The NVIDIA Linux results arrive after doing a similar AMD comparison from R600 graphics cards through the R9 Fury. However, that analysis found that for many of the older graphics cards, their open-source driver support regressed into an unworkable state. For the cards that did work, the performance gains were not nearly as significant over time.

You see, the company has partnered with Canonical to utilize Ubuntu for cloud, network, and enterprise applications. That's right, AT&T did not choose Microsoft's Windows when exploring options. Canonical will provide continued engineering support too.

An anonymous reader writes: In response to an article claiming Ubuntu didn't reach its goal of 200 million users this year — a goal set out by Mark Shuttleworth in 2011 to surpass 200 million users by 2015 — a Canonical engineer has come out to say the opposite. Dustin Kirkland, a member of Ubuntu Product and Strategy team, has come out to say there are more than one billion Ubuntu users. His billion tally though does include cloud/container instances as well as those shopping online at Wallmart, watching popular movies where the studios used Ubuntu servers, streamed from Netflix, rode with Uber, and other businesses that rely upon Ubuntu servers.

jones_supa writes: Canonical introduced Amazon Product Results as part of Ubuntu 12.10, which meant that local searches performed by a user in Dash were also sent online. This made many Ubuntu users spill their coffee and got criticism from EFF and FSF as well. The so called "Shopping Lens" had to be manually disabled if that kind of search behavior was not desired. Finally after years, Canonical is reacting to the negative feedback and respecting users' privacy, so that Ubuntu 16.04 (the next Long Term Support release) won't send local searches over the web by default. The Amazon search feature is still available for those who explicitly want to use it.
