Ubuntu: NGINX on Ubuntu Server 18.04, Pick, Departure From i386 and Pop!_OS 19.04 Overview

  • How to install the latest version of NGINX on Ubuntu Server 18.04

    NGINX is one of the most popular web servers on the planet. It's reliable, scalable, and easy to use. But did you know, if you install NGINX from the default Ubuntu Server 18.04 repositories, the version you get is out of date? You don't want that. In fact, you probably want the most up-to-date stable release of the software.

  • Pick – A Color Picker for Ubuntu with History Support

    For Ubuntu 18.04 and higher, you can easily install the tool from Ubuntu Software as it has been made as snap package.

  • Ubuntu Confirms It’s Dropping All 32-bit Support Going Forward

    Ubuntu has confirmed plans to drop all support for 32-bit (i386) systems going forward, beginning with the upcoming Ubuntu 19.10 release.

    The decision will mean that the distro no longer builds, packages or distributes any 32-bit software, libraries or tools on newer versions of Ubuntu.

    Users of Ubuntu 18.04 LTS 32-bit are not affected by today’s announcement and will (should?) continue to work as normal, with access to the existing 32-bit archive.

    But the move will mean they are unable to upgrade to a newer Ubuntu release — nope, not even the next LTS!

    Will such a major sounding change have much of an impact?

    Eh, no, not really.

    Ubuntu says it’s stranding a mere 1% of its current user base on 32-bit version Ubuntu 18.04 LTS (which isn’t terrible place to stay, as it is supported until 2023).

  • i386 architecture will be dropped starting with eoan (Ubuntu 19.10)
    Last year, the Ubuntu developer community considered the question of whether
    to continue carrying forward the i386 architecture in the Ubuntu archive for
    future releases.[1]  The discussion at the time was inconclusive, but in
    light of the strong possibility that we might not include i386 as a release
    architecture in 20.04 LTS, we took the proactive step to disable upgrades
    from 18.04 to 18.10 for i386 systems[2], to avoid accidentally stranding
    users on an interim release with 9 months of support instead of letting them
    continue to run Ubuntu 18.04 LTS with its 5 years of standard support.
    
    
    
    
    In February of this year, I also posted to communicate the timeline in which
    we would take a final decision about i386 support in 20.04 LTS[3], namely,
    that we would decide in the middle of 2019.
    
    
    
    
    The middle of 2019 has now arrived.   The Ubuntu engineering team has
    reviewed the facts before us and concluded that we should not continue to
    carry i386 forward as an architecture.   Consequently, i386 will not be
    included as an architecture for the 19.10 release, and we will shortly begin
    the process of disabling it for the eoan series across Ubuntu
    infrastructure.
    
    
    
    
    While this means we will not provide 32-bit builds of new upstream versions
    of libraries, there are a number of ways that 32-bit applications can
    continue to be made available to users of later Ubuntu releases, as detailed
    in [4].   We will be working to polish the 32-bit support story over the
    course of the 19.10 development cycle.  To follow the evolution of this
    support, you can participate in the discourse thread at [5].
  • Ubuntu 19.10 To Drop 32-bit x86 Packages

    Ubuntu and their downstream flavors all stopped shipping x86 32-bit images and now for the 19.10 cycle they have decided to stop their i386 support entirely. Beginning with Ubuntu 19.10, the archive/packages will not be built for x86 32-bit. 

    Longtime Ubuntu developer Steve Langasek announced their decision today that the i386 architecture will be dropped starting with Ubuntu 19.10, affecting all Ubuntu-based platforms / those relying upon the official Ubuntu Eoan archives.

Your first robotic arm with Ubuntu Core, coming from Niryo

Filed under
Hardware
Ubuntu

Niryo has built a fantastic 6-axis robotic arm called ‘Niryo One’. It is a 3D-printed, affordable robotic arm focused mainly on educational purposes. Additionally, it is fully open source and based on ROS. On the hardware side, it is powered by a Raspberry Pi 3 and NiryoStepper motors, based on Arduino microcontrollers. When we found out all this, guess what we thought? This is a perfect target for Ubuntu Core and snaps!

When the robotic arm came to my hands, the first thing I did was play with Niryo Studio; a tool from Niryo that lets you move the robotic arm, teach sequences to it and store them, and many more things. You can programme the robotic arm with Python or with a graphical editor based on Google’s Blocky. Niryo Studio is a great tool that makes starting on robotics easy and pleasant.

DJI spices up Matrice drones with 2nd Gen Manifold computer running Ubuntu with snaps

Filed under
Ubuntu

Canonical announced Ubuntu snaps support for DJI’s second-gen Manifold companion computer for its Matrice drones. The Manifold 2 offers a choice of Jetson TX2 or Intel Coffee Lake-U chips.

DJI’s industry leading drones such as its Phantom and Matrice models are directed by flight controllers that run a proprietary operating system. Yet, in 2015, the company announced a Manifold development computer for its Matrice 100 drone that runs Ubuntu on an Nvidia Tegra K1. A few weeks ago, DJI unveiled a more powerful Manifold 2 computer with a choice of Nvidia Jetson TX2 and Intel Core i7-8550U processors (see farther below). Canonical has followed up by announcing that not only will Ubuntu 16.04 return as the pre-installed OS for the device, but that it will include support for Ubuntu snaps application packages.

Developers Devising Plan To Ship Newer NVIDIA Drivers On Ubuntu Stable Releases

Filed under
Graphics/Benchmarks
Linux
Ubuntu

Currently NVIDIA's packaged drivers on Ubuntu can get a bit stale on Ubuntu stable releases since they aren't updated in-step with the latest driver releases. But a new stable release update (SRU) policy/exception similar to the Firefox approach is being made for Ubuntu so that new releases will end up working their way into currently supported Ubuntu series.

The Canonical developers working on Ubuntu are really ramping up their support for NVIDIA's proprietary driver. On top of Ubuntu 19.10 to bundle the NVIDIA binary driver into the operating system's ISO image, they are working out the SRU details for shipping newer NVIDIA driver releases on existing Ubuntu stable releases.

Regolith Linux is the i3 Ubuntu Spin You’ve Been Waiting For

Filed under
Ubuntu

Okay, okay. If you are sat there mouthing “what is i3?” at me with a confused, borderline-desperate look on your face, I’ll fill you in:

i3 is a tiling window manager created for X11 (the display manager most Linux distros use, including Ubuntu). i3 supports traditional horizontal vertical window tiling — think window snapping, but arranged and resized automatically — as well as stacking and tabbing.

The differences don’t end there, though.

Like me, you’re probably used to managing app windows with a mouse, but the i3 window manager is largely keyboard driven. The idea is that you use keyboard shortcuts to move, manage and arrange open apps and windows (though you can use a mouse too).

Give Ubuntu a Bold New Look with the Qogir Theme

GNOME
Ubuntu

The background imagery in the Nautilus file manager (the effect also apparently works with Nemo, but I haven’t tested it) is the most visually striking element in the Qogir theme.

It’s a love it/hate it gimmick, which explains why it’s rarely used. Personally I enjoy the visual flourish it adds (though it certainly helps if your desktop wallpaper compliments it).

Ubuntu: LXD, New Stuff and Snaps

Filed under
Ubuntu
  • Development in LXD

    Most of my development is done in LXD containers. I love this for a few reasons. It takes all of my development dependencies and makes it so that they're not installed on my host system, reducing the attack surface there. It means that I can do development on any Linux that I want (or several). But it also means that I can migrate my development environment from my laptop to my desktop depending on whether I need more CPU or whether I want it to be closer to where I'm working (usually when travelling).

    When I'm traveling I use my Pagekite SSH setup on a Raspberry Pi as the SSH gateway. So when I'm at home I want to connect to the desktop directly, but when away connect through the gateway.

  • Snap Store Is Available for Ubuntu!, How to Install It?

    Snap is a software used to install software packages that can run on various Linux distributions. This time Snap Store can be installed and used like using the Software Center (on Ubuntu), or GNOME Software. This application was created specifically to make it easier for users when installing software packages on Snap.

    Actually, the Ubuntu Software Center and GNOME software can add the url of a software package and install it. But both of these applications will mix search results that are snap, flatpak and others.

  • An OpenJPEG Surprise

    My previous blog post seems to have resolved most concerns about my requests for Ubuntu stable release updates, but I again received rather a lot of criticism for the choice to make WebKit depend on OpenJPEG, even though my previous post explained clearly why there are are not any good alternatives.

    I was surprised to receive a pointer to ffmpeg, which has its own JPEG 2000 decoder that I did not know about. However, we can immediately dismiss this option due to legal problems with depending on ffmpeg. I also received a pointer to a resurrected libjasper, which is interesting, but since libjasper was removed from Ubuntu, its status is not currently better than OpenJPEG.

    But there is some good news! I have looked through Ubuntu’s security review of the OpenJPEG code and found some surprising results. Half the reported issues affect the library’s companion tools, not the library itself. And the other half of the issues affect the libmj2 library, a component of OpenJPEG that is not built by Ubuntu and not used by WebKit. So while these are real security issues that raise concerns about the quality of the OpenJPEG codebase, none of them actually affect OpenJPEG as used by WebKit. Yay!

  • Call for testing: chromium-browser deb to snap transition

    The chromium browser has been available as a deb package for all supported Ubuntu releases and as a snap since version 60, and the time has come to start transitioning away from the debs.

  • Canonical Announces Embedded Computer Manifold 2 for Drone Developers, Request For Help Testing Snap Package, PHP v7.4.0 Available, PyCharm 2019.2 EAP3 Released, Talks To Port Over Microsoft's Chromium-Based Edge browser To Linux

    Yesterday, Canonical, the company behind Ubuntu announced the availability of Manifold 2, a high-performance embedded computer offered by leading enterprise drone manufacturer, DJI. This availability will allow developers access to containerized software packages (e.g. Snaps), allowing for infinite evolution and functionality changes.

    It looks as if Ubuntu is transitioning the Chromium Debian package to a Snap one. The community behind this effort is asking for assistance in testing the Snap package.

Canonical's Linux Snap Store Adds 10 Distro-Specific Installation Pages For Every App

Filed under
Linux
Ubuntu

Canonical's Snap Store -- a fairly distro-agnostic solution for easily installing a wide variety of apps -- is loaded up and ready to go in Linux distributions like Zorin OS and Ubuntu. It's also supported on dozens of others including Arch, Linux Mint, Manjaro and elementary OS, provided you install the Snapd service first. Now it looks like Canonical is striving to make the entire experience more user-friendly by serving up distro-specific landing pages for every single app in the Snap Store.

They look pretty slick, too.

For example, if you want to install something like Telegram, the Snap Store is ready to serve up a unique page, complete with an appropriately colored and logo-laden background explaining how to install both the required Snapd service and the app for the distro you're using. In the screenshot below, you'll notice commands to pull Snapd from the AUR (Arch User Repository), enable the service and then install Telegram Desktop.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

Red Hat and SUSE Leftovers

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.

    This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications. Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.

NSA Back Doors in Windows Causing Chaos While Media is Obsessing Over DoS Linux Bug

  • U.S. Government Announces Critical Warning For Microsoft Windows Users
    The United States Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) has gone public with a warning to Microsoft Windows users regarding a critical security vulnerability. By issuing the "update now" warning, CISA has joined the likes of Microsoft itself and the National Security Agency (NSA) in warning Windows users of the danger from the BlueKeep vulnerability. This latest warning, and many would argue the one with most gravitas, comes hot on the heels of Yaniv Balmas, the global head of cyber research at security vendor Check Point, telling me in an interview for SC Magazine UK that "it's now a race against the clock by cyber criminals which makes this vulnerability a ticking cyber bomb." Balmas also predicted that it will only be "a matter of weeks" before attackers started exploiting BlueKeep. The CISA alert appears to confirm this, stating that it has, "coordinated with external stakeholders and determined that Windows 2000 is vulnerable to BlueKeep." That it can confirm a remote code execution on Windows 2000 might not sound too frightening, this is an old operating system after all, it would be unwise to classify this as an exercise in fear, uncertainty and doubt. Until now, the exploits that have been developed, at least those seen in operation, did nothing more than crash the computer. Achieving remote code execution brings the specter of the BlueKeep worm into view as it brings control of infected machines to the attacker.
