  • Ubuntu 14.04 LTS Gets Compiler-Based Retpoline Kernel Mitigation for Spectre V2

    Canonical announced today the availability of a new kernel security update for Ubuntu 14.04 LTS (Trusty Tahr) operating systems running the Linux 3.13 kernel to fix the second variant of the Spectre vulnerability on both 32-bit and 64-bit installations.

    On January 23, 2018, Canonical updated the kernel packages of Ubuntu 14.04 LTS (Trusty Tahr) to version linux-image 3.13.0-141.190, patching the Spectre Variant 2 security vulnerability discovered by Jann Horn, for the 64-bit (amd64) hardware architecture.

    The Spectre flaw can be exploited by a local attacker to expose sensitive information from kernel memory on modern microprocessors with branch prediction and speculative execution capabilities. Canonical now added support for 32-bit hardware architectures as well for Ubuntu 14.04 LTS systems.

  • Kotlin Programming Language Now Available On Linux Distros As A Snap

    Over the past year, the adoption of Kotlin programming language has increased at a rapid pace. Apart from its long list of great features, Google’s announcement of making Kotlin an officially supported language for Android development was a major reason behind the same. Being a general-purpose language, Kotlin can also be used on various applications as well.

Ubuntu 'Bionic Beaver' 18.04 Beta 1

Filed under
  • 18.04 Beta 1 Released For Opt-In Ubuntu Flavors

    Today marks the first beta release of opt-in flavors participating for the Ubuntu 18.04 "Bionic Beaver" development cycle.

    Ubuntu itself continues to skip these development releases in favor of focusing on daily quality of their ISOs. The flavors participating this round for today's beta release are Kubuntu, Ubuntu Budgie, Ubuntu Kylin, Ubuntu MATE, and Xubuntu.

  • Bionic Beaver 18.04 Beta 1 Released!

    "The beaver told the rabbit as they stared at the Hoover Dam: No, I didn't
    build it myself, but it's based on an idea of mine".
    -- Charles Hard Townes

    The first beta of the Bionic Beaver (to become 18.04) has now been
    released, and is available for download!

    This milestone features images for Kubuntu, Ubuntu Budgie, Ubuntu Kylin,
    Ubuntu MATE, and Xubuntu.

    Pre-releases of the Bionic Beaver are *not* encouraged for anyone needing a
    stable system or anyone who is not comfortable running into occasional,
    even frequent breakage. They are, however, recommended for Ubuntu flavour
    developers and those who want to help in testing, reporting, and fixing
    bugs as we work towards getting this release ready.

  • Ubuntu MATE 18.04 Beta 1

    We’ve been refining Ubuntu MATE since the 17.10 release and making improvements to ensure that Ubuntu MATE offers what our users want today and what they’ll need over the life of this LTS release. This is what’s changed since 17.10.

  • Kubuntu Bionic Beaver (18.04) Beta 1 Released!

Ubuntu 18.04 LTS (Bionic Beaver) Beta Released for Opt-In Flavors, Download Now

Filed under

Ubuntu 18.04 LTS (Bionic Beaver) had one of the busiest development cycles, especially due to the Meltdown and Spectre security vulnerabilities, but also because of other causes, including the not very well planned release schedule.

For example, the opt-in flavors were supposed to get two alpha releases, the first one within a week and a half after the New Year's Eve and the second one on February 1st. None of these alpha milestones happened, so that's why we're now seeing the beta.

Kubuntu, Ubuntu 17.10 Users Can Now Install the Latest KDE Plasma 5.12.3 Desktop

Filed under

The KDE Project released earlier this week the third bugfix update to their long-term supported KDE Plasma 5.12 desktop environment, and Ubuntu/Kubuntu 17.10 (Artful Aardvark) users are among the first to install it. The update brings an impressive list of improvements for the Plasma Discover package manager.

While Kubuntu/Ubuntu 17.10 users are already receiving the most recent stable KDE Plasma packages, it looks like Ubuntu 18.04 (Bionic Beaver) early adopters will have to wait a little longer for the new updates, as the upcoming operating system is currently in Beta freeze and the repositories are blocked.

Checking Out Ubuntu 18.04's Minimal Desktop Install Option

Filed under

Besides the Ubuntu 18.04 minimal spin that is around to 30MB compressed, the Ubuntu 18.04 "Bionic Beaver" installer recently added an option for a "minimal installation" from the desktop Live DVD/USB environment. Here's a look at what that means for desktop users.

The minimal installation option from the Ubuntu 18.04 Ubiquity installer isn't to be confused with the lightweight Ubuntu minimal spin for containers and building your Ubuntu stack from scratch. Rather, the desktop minimal installation is advertised as only installing "a minimal desktop environment with a browser and utilities."

    Finally, I updated my Debian packaging with Git notes, and wrote new notes on using sbuild.

  • Women in MiniDebConf Curitiba campaign

    Here is what Anna has to say about Debian: "Debian is one of the strongest GNU/Linux distributions with the free software philosophy, and that's why it's so impressive. Anyone who comes in contact with Debian necessarily learns more about free software and the FLOSS culture."

  • Debian/TeX Live 2017.20180305-1

    TeX Live 2017 has received its final update just the other day and we are moving forward to start the period of testing leading up to the release of TeX Live 2018. Thus, this release for Debian is also the last one based on the TeX Live 2017, and updates based on TeX Live 2018 pretest will hit experimental in the next days. This release does not bring too much new items, mostly a bug fix for upgrades from Jessie, plus the usual bunch of updated packages, see below.

Exton|OS Claims to Be First Distribution Based on Ubuntu 18.04 LTS, Linux 4.16

Filed under

Tagged as Build 180301, the new Exton|OS release is based on Ubuntu 18.04 LTS and features the lightweight and modern Budgie desktop environment created by the Solus devs. Budgie 10.4 is on-board this release, which comes with the renowned Calamares universal installer framework by default.

According to the developer, Exton|OS is now fully compatible with the software repositories of Ubuntu 18.04 LTS, which means that users can install any upstream package they need. Also, Arne Exton claims Exton|OS would be the first GNU/Linux distro to be based on Ubuntu 18.04 LTS (Bionic Beaver), due for release on April 26, 2018.

Xubuntu and Xfce Released

Filed under
  • Testing for Xubuntu

    Xubuntu 18.04 “Bionic Beaver” is just around the corner. The first beta milestone arrives next week, and the final release is a little over a month away. 18.04 is an LTS release, meaning it has a 3-year support cycle and is definitely recommended for all users. Or it would be, if we knew it was ready. Stick around… this is a bit of a long read, but it’s important.

    The ISO Tracker has seen little activity for the last few development cycles. We know we have some excited users already using and testing 18.04. But without testing results being recorded anywhere, we have to assume that nobody is testing the daily images and milestones. And this has major implications for both the 18.04 release and the project as a whole.

  • Parole Media Player 1.0.0 Released

Thread-optimized IoT gateway adds Ubuntu Core support

Filed under

Rigado announced that its i.MX6 UL based Vesta IoT Gateway, which offer Ethernet, WiFi, BT, Thread, and optional LTE, LoRa, and PoE, will soon be available with Ubuntu Core and Canonical’s IoT app store.

Starting this summer, Portland, Oregon-based Rigado will offer its Edge Connectivity gateway solutions with Canonical’s IoT-focused, transactional Ubuntu Core distribution. Rigado is referring to its low-cost, Yocto Project powered Vesta IoT Gateway, which launched in Dec. 2016 without the Vesta name. The new Ubuntu Core support will enable “sophisticated control, monitoring and tracking applications,” as well as “connected guest experiences,” says Canonical in its version of the announcement.

How to build something ‘useful’ with a Raspberry Pi

In honor of Pi Day, Chaim Gartenberg and I cooked up a tiny little Raspberry Pi project for yesterday’s episode of Circuit Breaker Live. We started with a simple concept: a button that says “Why?” when you press it, in honor of our favorite podcast. So we knew we’d need a button, some sound files, a little bit of Python code, and, of course, a Raspberry Pi. A new Pi is $35, but we found an old Raspberry Pi 2 in my desk drawer, which was up to the task. (Newer Pis have built-in Wi-Fi and faster processors, but for our simple button project we didn’t need internet or extra horsepower.) Read more

Graphics: AMDGPU, Mesa 17.3.7, RADV

  • Linux 4.17 To Enable AMDGPU DC By Default For All Supported GPUs
    Since the introduction of the AMDGPU DC display code (formerly known as DAL) in Linux 4.15, this modern display stack has just been enabled by default for newer Radeon Vega and Raven Ridge devices. With Linux 4.17 that is changing with AMDGPU DC being enabled by default across the board for supported GPUs. Building off the earlier DRM-Next material for Linux 4.17, Alex Deucher minutes ago sent in another round of feature updates for targeting this next kernel cycle. This latest batch has continued code refactoring around PowerPlay, support for fetching the video RAM type from the video BIOS, allowing the TTM memory manager to drop its backing store when not needed, DC bandwidth calculation updates, enabling DC backlight control for pre-DCE11 GPUs, various display code fixes, and other bug fixes.
