Filed under
Ubuntu

Ubuntu 18.04.1 LTS is the first point release of the Ubuntu 18.04 LTS (Bionic Beaver) operating system series, due for release this Thursday on July 26, 2018, and Canonical now wants the community to help test the Release Candidate images before the final builds hit the streets for all supported flavors.

"These builds have bionic-proposed enabled and are not final. Despite this, please test your images and do not wait for a "final" build to test. We need you testing now, iterating uploads to get your bugs fixed, filing bugs and escalating where you need help," said Jean-Baptiste Lallement in a mailing list announcement.

Canonical Donates More Devices to UBports to Keep Ubuntu Touch Dream Alive

Filed under
Ubuntu

It isn't the first time Canonical donates devices to UBports, as back in February the company behind Ubuntu donated a total of 38 Ubuntu Phones consisting of 18 x BQ Aquaris E5 HD and 20 x Meizu MX4 to the project that continues to develop the Ubuntu Touch mobile operating system for a bunch of phones and tablets.

Today, UBports reports that Canonical donated them yet another batch of devices, and Dalton Durst confirmed for Softpedia that they received 4 x Nexus 10 tablets, 4 x Nexus 7 tablets, and a Meizu MX4 phone. With these new devices, the UBports project will continue to keep the Ubuntu Phone and Ubuntu Touch dreams alive as long as possible for the community and those who still use them.

The “Khadas Edge” SBC runs Linux or Android on a Rockchip RK3399 and offers WiFi/BT, HDMI 2.0, USB 3.0 and 2.0, and dual USB Type-C ports, as well as an MXM3 connector to plug into an upcoming “Khadas Captain” carrier.

Shenzhen Wesion’s Khadas project has posted specs for a “Khadas Edge” board that combines attributes of both a single board computer and a computer-on-module. Unlike the Amlogic based Khadas Vim and Khadas Vim2 SBCs, the Khadas Edge features the hexa-core Rockchip RK3399. Presumably, the Khadas Edge will be an open-spec board like the similarly dimensioned, 82 x 57.5mm Vim models. OS support includes Android Oreo, Ubuntu 18.04, and Debian 9.0 with mainline Linux.

ExTiX "The Ultimate Linux System" Now Uses Linux 4.18, Based on Ubuntu 18.04 LTS

Filed under
Linux
Ubuntu

Based on packages from the Ubuntu 18.04 LTS (Bionic Beaver) and Debian GNU/Linux 9 "Stretch" operating system series, ExTiX 18.7 is the first release of the GNU/Linux distribution to use the forthcoming Linux 4.18 kernel series, which is currently in development and should hit the streets early next month.

Arne Exton was brave enough to rebase his ExTiX Linux operating system on the fifth Release Candidate of Linux kernel 4.18, which is patched to allow the installation of Nvidia’s proprietary graphics drivers. Arne Exton's 4.18.0-rc5-extix kernel replaces kernel 4.16.2-exton used in the previous release, but it's an unstable kernel.

Ubuntu/GNOME Theme and Improving GHashTable

  • Ubuntu 18.10's New Community Theme Is Named Yaru, Here's What It Looks Like

    Ubuntu contributor Didier Roche announced today the name and plans of the community theme that's being prepared for the upcoming Ubuntu 18.10 (Cosmic Cuttlefish) release.

    As you're probably aware the Ubuntu 18.10 (Cosmic Cuttlefish) operating system will feature brand-new system theme and icons by default for new installations, and the theme has been developed by various members of the Ubuntu community instead of Canonical's employees. Until today, the theme was known as Communitheme, but from now on it's called Yaru.

  • Didier Roche: Open The Cosmic Gate: A beautiful theme gets a beautiful name

    Communitheme has been a community effort from the start with an overwhelming amount of feedback from an even larger community. Surprisingly, the still ongoing discussion thread of more than 1500 messages hasn’t (yet?) broken discourse!

    However, the effort to refresh the look and feel of Ubuntu has gone way beyond just a theme. From the start, Sam Hewitt’s beautiful Suru icons were included and over time, the effort brought new system sounds and new cursors under its wing. Some of the design discussions have gone even further than this, but the desire to stay as close to upstream GNOME as possible has put most of those in the freezer for now. So, in order to reflect the broad scope and in light of its upcoming inclusion in Ubuntu, a new name is in order.

    [...]

    Note that screenshots are still Work In Progress, there is still some discussions about keeping the Ubuntu logo by default on the launcher or not and other fundamentals changes that the community can decide until the Cosmic Cuttlefish release.

  • A hash table re-hash

    Hash tables! They’re everywhere. They’re also pretty boring, but I’ve had GLib issue #1198 sitting around for a while, and the GNOME move to GitLab resulted in a helpful reminder (or two) being sent out that convinced me to look into it again with an eye towards improving GHashTable and maybe answering some domain-typical questions, like “You’re using approach X, but I’ve heard approach Y is better. Why don’t you use that instead?” and “This other hash table is 10% faster in my extremely specific test. Why is your hash table so bad?”.

    And unfairly paraphrased as those questions may be, I have to admit I’m curious too. Which means benchmarks. But first, what exactly makes a hash table good? Well, it depends on what you’re looking for. I made a list.

  • Ubuntu Weekly Newsletter Issue 537

    Welcome to the Ubuntu Weekly Newsletter, Issue 537 for the week of July 15 – 21, 2018

  • Desktop team report from GUADEC 2018

    This year’s GUADEC [https://2018.guadec.org/] (GNOME Users And Developers Conference) took place in Almeria, Spain. The main conference was from 6th to 11th July, and for a few days prior to that where the GNOME Advisory Board met for an in-person catch up, and a few days afterwards for BOF days where developers met to discuss and work on specific topics which were interesting to them.

    Canonical are proud to have sponsored the conference and to send seven members of the Ubuntu Desktop team. We had a great conference and are already looking forward to next year.

  • Ubuntu 17.10 is no longer supported

    Those who are still using Ubuntu 17.10 "Artful Aardvark" should now update to the version 18.04 (nicknamed "Bionic Beaver") of this popular Linux distribution. Ubuntu 17.10 arrived on October 19, 2017, and it only received 9 months of support — as it happens with all non-LTS Ubuntu Linux releases.

Canonical Fixes Boot Failures on Ubuntu 18.04 LTS and 16.04 LTS, Update Now

Filed under
Ubuntu

About two weeks ago, Canonical patched a regression that would lead to boot failures on some AMD machines using the Ubuntu 14.04 LTS (Trusty Tahr) operating system series, which was caused by a microcode firmware update for AMD processors that was supposed to mitigate the well-known Spectre microprocessor side-channel security vulnerability.

Earlier this month, on July 2, Canonical released a Linux kernel security update for Ubuntu 18.04 LTS (Bionic Beaver) users, addressing a total of six security vulnerabilities, one of which introduced a regression also causing boot failures, though it doesn't appear to be limited to AMD processors only, but also to Intel machines.

  • PowerShell launches as a snap

    PowerShell Core from Microsoft is now available for Linux as a Snap. Built on the .NET Framework, PowerShell is an open source task-based command-line shell and scripting language with the goal of being the ubiquitous language for managing hybrid cloud assets. It is designed specifically for system administrators and power-users to rapidly automate the administration of multiple operating systems and the processes related to the applications that run on those operating systems.

  • PowerShell Core now available as a Snap package

    The goal of PowerShell Core is to be the ubiquitous language for managing your assets in the hybrid cloud. That’s why we’ve worked to make it available on many operating systems, architectures, and flavors of Linux, macOS, and Windows as possible.

  • Microsoft's PowerShell Available on Ubuntu as a Snap, Here's How to Install It

    Canonical and Microsoft announced today that PowerShell automation and configuration management system is now available as a Snap package for Ubuntu Linux and other Snap-enabled GNU/Linux distributions.

    Consisting of a cross-platform command-line shell and related scripting language, as well as a framework for dealing with cmdlets, Microsoft's PowerShell works on Windows, macOS, and Linux platforms to allow power-users and system administrators to have better and automated control over the administration of several operating systems.

  • Microsoft's PowerShell Now Available On Ubuntu In Snap Form

    Canonical and Microsoft have just announced that PowerShell Core is now available for Ubuntu users in Snap format.

    Back in the summer of 2016, Microsoft open-sourced PowerShell with plans to support Linux. PowerShell has been available on Linux for a while now without too much adoption while now it's available in Snap form for making it easy to deploy on Ubuntu and other Snap-supported platforms.

4 Neat New GTK Themes for Your Linux Desktop

The new Yaru/Communitheme theme might be the talk of the Ubuntu town right now, but it’s not the only decent desktop theme out there. If you want to give your Linux desktop a striking new look ahead of the autumn then the following quad-pack of quality GTK themes might help you out. Don’t be put off by the fact you will need to manually install these skins; it’s pretty to install GTK themes on Ubuntu 18.04 LTS above, providing you set hidden folders to show (Ctrl + H) in Nautilus first.

Python wriggles onward without its head

At the third annual PyBay Conference in San Francisco over the weekend, Python aficionados gathered to learn new tricks and touch base with old friends. Only a month earlier, Python creator Guido van Rossum said he would step down as BDFL – benevolent dictator for life – following a draining debate over the addition of a new way to assign variables within an expression (PEP 572). But if any bitterness about the proposal politics lingered, it wasn't evident among attendees. Raymond Hettinger, a Python core developer, consultant and speaker, told The Register that the retirement of Python creator Guido van Rossum hasn't really changed things. "It has not changed the tenor of development yet," he said. "Essentially, [Guido] presented us with a challenge for self-government. And at this point we don't have any active challenges or something controversial to resolve." Read more

    With UEFI BIOS updating now working well with the Fwupd firmware updating utility and Linux Vendor Firmware Service (LVFS) for distributing these UEFI update capsules, Richard Hughes at Red Hat is next focusing on NVMe solid-state drives for being able to ship firmware updates under Linux. Hughes is in the early stages at looking to support NVMe firmware updates via LVFS/fwupd. Currently he is hoping for Linux users with NVMe drives to send in the id-ctrl identification data on your drives to him. This data will be useful so he knows what drives/models are most popular but also for how the firmware revision string is advertised across drives and vendors.
  • [Older] Language, Networking Packages Get Updates in Tumbleweed
    There were two openSUSE Tumbleweed snapshots this past week that mostly focused on language and network packages. The Linux Kernel also received an update a couple days ago to version 4.17.13. The packages in the 20180812 Tumbleweed snapshot brought fixes in NetworkManager-applet 1.8.16, which also modernized the package for GTK 3 use in preparations for GTK 4. The free remote desktop protocol client had its third release candidate for freerdp 2.0.0 where it improved automatic reconnects, added Wave2 support and fixed automount issues. More network device card IDs for the Intel 9000 series were added in kernel 4.17.13. A jump from libstorage-ng 4.1.0 to version 4.1.10 brought several translations and added unit test for probing xen xvd devices. Two Common Vulnerabilities and Exposures fixes were made with the update in postgresql 10.5. Several rubygem packages were updated to versions 5.2.1 including rubygem-rails 5.2.1, which makes the master.key file read-only for the owner upon generation on POSIX-compliant systems. Processing XML and HTML with python-lxml 4.2.4 should have fewer crashes thanks to a fix of sporadic crashes during garbage collection when parse-time schema validation is used and the parser participates in a reference cycle. Several YaST packages receive updates including a new ServiceWidget to manage the service status with yast2-ftp-server 4.1.3 as well with yast2-http-server, yast2-slp-server and yast2-squid 4.1.0 versions.

    Tech is commoditizing. I've talked about this before; I think networking is commoditizing at the device level, and the days of appliance-based networking are behind us. But are networks themselves a commodity? Not any more than any other system. We are running out of useful features, so vendors are losing feature differentiation. This one is going to take a little longer… When I first started in network engineering, the world was multiprotocol, and we had a lot of different transports. For instance, we took cases on IPX, VIP, Appletalk, NetBios, and many other protocols. These all ran on top of Ethernet, T1, Frame, ATM, FDDI, RPR, Token Ring, ARCnet, various sorts of serial links ... The list always felt a little too long, to me. Today we have IPv4, IPv6, and MPLS on top of Ethernet, pretty much. All transports are framed as Ethernet, and all upper layer protocol use some form of IP. MPLS sits in the middle as the most common "transport enhancer." The first thing to note is that space across which useful features can be created is considerably smaller than it used to be.
  • Meetings that make people happy: Myth or magic?
    People tend to focus on the technical elements of meeting prep: setting the objective(s), making the agenda, choosing a place and duration, selecting stakeholders, articulating a timeline, and so on. But if you want people to come to a meeting ready to fully engage, building trust is mission-critical, too. If you need people to engage in your meetings, then you're likely expecting people to come ready to share their creativity, problem-solving, and innovation ideas.

    "The real freedom you get from open source projects is much more, and more important than the fact that you don't have to pay for it," Frank Gürkaynak, Director of ETHZ's Microelectronics Design Center, writes in an article posted on All About Circuits. "Researchers can take what we provide and freely change it for their experiments. Startup companies can build on what we provide as a starting point and concentrate their time and energy on the actual innovations they want to provide. And people who are disturbed by various attacks on their systems [1, 2] have the chance to look inside and know what exactly is in their system."

  • Fund Meant to Protect Elections May Be Too Little, Too Late
    The Election Assistance Commission, the government agency charged with distributing federal funds to support elections, released a report Tuesday detailing how each state plans to spend a total of $380 million in grants allocated to improve and secure their election systems. But even as intelligence officials warn of foreign interference in the midterm election, much of the money is not expected to be spent before Election Day. The EAC expects states to spend their allotted money within two to three years and gives them until 2023 to finish spending it. Election experts have expressed skepticism that the money will be enough to modernize election equipment and secure it against state-sponsored cyber threats.
