Ubuntu 2018 Recap: From Memory Leak to Marvellous LTS

Filed under

Ubuntu began the year on a buoyant note, carried high by a wave of (much-needed) positive press resulting from the release of Ubuntu 17.10 ‘Artful Aardvark’ a few months prior.

But with a new long-term support release looming large, a reimagined installer to debate, and a gaping memory hole to plug in GNOME Shell, the rest of 2018 was a little less plain sailing for Ubuntu’s engineers!

In this post we take a look back at Ubuntu’s key moments in 2018, plus give a shout-out to the notable Snap app releases that showed up along the way…

Ubuntu 19.04 Makes It Easier to Manage Reboot-free Kernel Updates

Filed under

Users of Canonical’s Livepatch service — which lets you install Linux kernel updates without rebooting — will find additional settings available in Ubuntu 19.04.

The feature, which made its desktop debut in Ubuntu 18.04 LTS, is free for Ubuntu desktop users on up to three separate machines.

The Ubuntu Welcome screen includes live patch set-up as part of its fresh-install orientation but is easily skipped.

Lubuntu kicks 32-bit Linux users to the curb

Filed under

It is the year 2018, and 2019 is right around the corner -- 64-bit processors have been mainstream for a really long time. If you are still using a computer that is 32-bit only, it is time to toss it into a dumpster. No, I’m not being an elitist; it is simply time to move on. A much superior laptop can be had new for a few hundred bucks. Hell, you could probably buy a used 64-bit machine for under $100.

With all of that said, I am proud of all Linux-based operating system maintainers that have the courage to ditch 32-bit processor support. Some misguided Linux community members will decry this, claiming that the open source kernel can breathe new life into old hardware. That’s true, but it’s time for the world to raise the bar on what the bottom is -- all hardware can’t be supported forever. The latest major operating system to drop 32-bit support? Lubuntu.

Canonical/Ubuntu: Robotics, Design and Lubuntu Deprecating i386

Filed under
  • An ‘App Store’ for robots? It’s coming and it’s a game-changer [Ed: Canonical targets the robotics market with Ubuntu]

    Subscription-based robotics models are already being implemented in an industrial setting by Small Robot Company, with farming-as-a-service ensuring farmers only pay for the exact work achieved by the robot, rather than the robot itself.

    Businesses will then be able to learn on the job and develop solutions on top of the hardware, such as real-time packaging or predictive maintenance. Value, therefore, is extended beyond the initial point of sale.

    Increasing robots’ longevity and usefulness through apps could hold the answer to accelerating their adoption across different industries for years to come.

    As we learned from the Apple App Store, democratizing software distribution can be a game-changer and make a device much greater than the sum of its parts.

  • [ubuntu] Design and Web team summary – 19 December 2018
  • [Lubuntu] Sunsetting i386

    Lubuntu has been and continues to be the go-to Ubuntu flavor for people who want the most from their computers, especially older hardware that cannot handle today’s workloads. However, the project and computing as a whole has drastically changed in many ways since its origin ten years ago. Computers have become faster, more secure, and most notably, have moved off of the traditional 32-bit i686 (generalized as i386 in Debian and Ubuntu) architecture.

    As an increasing number of Linux distributions have focused their attention on the 64-bit x86 architecture (amd64) and not on i386, we have found that it is harder to support than it once was. With i386-only machines becoming an artifact of the past, it has become increasingly clear to the Lubuntu Team that we need to evaluate its removal from the architectures we support. After careful consideration, we regret to inform our users that Lubuntu 19.04 and future versions will not see a release for the i386 architecture. Please do note that we will continue to support Lubuntu 18.04 LTS i386 users as a first-class citizen until its End of Life date in April of 2021.

  • Lubuntu Will Stop Providing 32-Bit Releases - Starting With 19.04

    The Lubuntu developers have announced today that their LXDE/LXQt downstream of Ubuntu Linux will no longer be offering 32-bit x86 releases moving forward while Lubuntu 18.04 LTS will continue to be supported. 

    Earlier this month Xubuntu announced that their Xfce spin would stop offering 32-bit ISOs for future releases. That left Lubuntu as the last of major Ubuntu derivatives providing 32-bit ISOs. But now the team announced today they too are parting ways with 32-bit releases.

Ubuntu-based Linux Mint 19.1 'Tessa' finally available with Cinnamon, MATE, or Xfce

The mainstreaming of Linux is accelerating every day. Many servers use Linux distributions, while Android remains the undisputed king of mobile. True, adoption of operating systems based on the open source kernel are still virtually nonexistent on the desktop, but as Windows 10 gets worse and worse, more and more home users may turn to Ubuntu, Google Chrome OS, and others. Just yesterday, Dell updated two of its mobile workstations to the latest Ubuntu LTS version.

  • Bring Back Desktop Icons on GNOME 3.30

    If you use GNOME 3.30 or later, you may find that 'icons on desktop' feature does not exist anymore. You cannot add anything to your personal Desktop folder like you usually did. Fortunately, thanks to csoriano, this removed feature can be added back by installing Desktop Icons  extension. You will find this extension useful if you use latest GNOME on Fedora, Arch, openSUSE, and Ubuntu if the Nautilus version is over 3.26. This article shows how it looks from openSUSE Tumbleweed GNOME. Try it and enjoy!

Ubuntu: Nautilus 3.30 and Mir 1.1.0 Release

  • Nautilus 3.30 Lands In Ubuntu 19.04 Disco Dingo

    Nautilus 3.30 has landed in Ubuntu 19.04 Disco Dingo. The application has finally been updated after staying at version 3.26 for the past two Ubuntu releases.

    As many users are probably aware, Ubuntu 18.04 and 18.04 use an older version of Nautilus (3.26) because the default Gnome file manager lots its desktop icons functionality with version 3.28, and the Ubuntu devs wanted to keep this functionality.

    About a month ago, Desktop Icons, a Gnome Shell extension that brings back desktop icons in Gnome, was added to the Ubuntu 19.04 Disco Dingo repositories. Thanks to this extension, the desktop icons functionality is no longer needed in Nautilus, so the default Gnome file manager was finally updated to the latest version (3.30) in Ubuntu 19.04 Disco Dingo.

  • Mir 1.1.0 Release

    We’re pleased to announce the release of Mir 1.1.0. The main thing to note with this release is a new package mir-graphics-drivers-nvidia with support for Nvidia binary “eglstream” drivers.

    There are also some bugfixes and some changes upstreamed by PostmarketOS developers building Mir on Musl and the UBports developers preparing to update the Mir version used by their Ubuntu Touch phones.

  • Mir 1.1 Released With EGLStreams KMS Support To Work With NVIDIA's Binary Driver

    The Canonical developers maintaining the Mir display server with its modern focus on being a Wayland compositor have just issued Mir 1.1.

    The primary addition with Mir 1.1 is the introduction of NVIDIA proprietary driver support by means of adding an EGLStreams KMS back-end that is compatible with the NVIDIA Linux driver architecture. If you are on the latest NVIDIA Linux drivers, it's now possible to fire up Mir 1.1 and enjoy its functionality and Wayland support.

Opening Files with Qt on Android

After addressing Android support in KF5Notifications another fairly generic task that so far required Android specific code is next: opening files. Due to the security isolation of apps and the way the native “file dialog” works on Android this is quite different from other platforms, which makes application code a bit ugly. This can be fixed in Qt though. Read more

Ubuntu-Centric Full Circle Magazine and Debian on the Raspberryscape

  • Full Circle Magazine: Full Circle Weekly News #121
  • Debian on the Raspberryscape: Great news!
    I already mentioned here having adopted and updated the Raspberry Pi 3 Debian Buster Unofficial Preview image generation project. As you might know, the hardware differences between the three families are quite deep ? The original Raspberry Pi (models A and B), as well as the Zero and Zero W, are ARMv6 (which, in Debian-speak, belong to the armel architecture, a.k.a. EABI / Embedded ABI). Raspberry Pi 2 is an ARMv7 (so, we call it armhf or ARM hard-float, as it does support floating point instructions). Finally, the Raspberry Pi 3 is an ARMv8-A (in Debian it corresponds to the ARM64 architecture). [...] As for the little guy, the Zero that sits atop them, I only have to upload a new version of raspberry3-firmware built also for armel. I will add to it the needed devicetree files. I have to check with the release-team members if it would be possible to rename the package to simply raspberry-firmware (as it's no longer v3-specific). Why is this relevant? Well, the Raspberry Pi is by far the most popular ARM machine ever. It is a board people love playing with. It is the base for many, many, many projects. And now, finally, it can run with straight Debian! And, of course, if you don't trust me providing clean images, you can prepare them by yourself, trusting the same distribution you have come to trust and love over the years.

OSS: SVT-AV1, LibreOffice, FSF and Software Freedom Conservancy

  • SVT-AV1 Already Seeing Nice Performance Improvements Since Open-Sourcing
    It was just a few weeks ago that Intel open-sourced the SVT-AV1 project as a CPU-based AV1 video encoder. In the short time since publishing it, there's already been some significant performance improvements.  Since the start of the month, SVT-AV1 has added multi-threaded CDEF search, more AVX optimizations, and other improvements to this fast evolving AV1 encoder. With having updated the test profile against the latest state as of today, here's a quick look at the performance of this Intel open-source AV1 video encoder.

  • What I learned during my internship with the FSF tech team
    Hello everyone, I am Hrishikesh, and this is my follow-up blog post concluding my experiences and the work I did during my 3.5 month remote internship with the FSF. During my internship, I worked with the tech team to research and propose replacements for their network monitoring infrastructure. A few things did not go quite as planned, but a lot of good things that I did not plan happened along the way. For example, I planned to work on GNU LibreJS, but never could find enough time for it. On the other hand, I gained a lot of system administration experience by reading IRC conversations, and by working on my project. I even got to have a brief conversation with RMS! My mentors, Ian, Andrew, and Ruben, were extremely helpful and understanding throughout my internship. As someone who previously had not worked with a team, I learned a lot about teamwork. Aside from IRC, we interacted weekly in a conference call via phone, and used the FSF's Etherpad instance for live collaborative editing, to take notes. The first two months were mostly spent studying the FSF's existing Nagios- and Munin-based monitoring and alert system, to understand how it works. The tech team provided two VMs for experimenting with Prometheus and Nagios, which I used throughout the internship. During this time, I also spent a lot of time reading about licenses, and other posts about free software published by the FSF.
