Filed under
Security
Ubuntu

After releasing a major kernel update for the Ubuntu 17.10 (Artful Aardvark) operating system series on both 64/32-bit and Raspberry Pi 2 devices, Canonical released an important kernel update for Ubuntu 16.04 LTS (Xenial Xerus) systems.

The new kernel update published earlier this week addresses a total of 39 security vulnerabilities for the long-term supported Ubuntu 16.04 LTS (Xenial Xerus) operating system series and its official derivatives, including Kubuntu, Lubuntu, Xubuntu, Ubuntu MATE, Ubuntu Kylin, and Ubuntu Studio.

Canonical Releases Major Linux Kernel Update for Ubuntu 17.10 for Raspberry Pi 2

Filed under
Ubuntu

Canonical released a major Linux kernel update for Ubuntu 17.10 for Raspberry Pi 2, addressing various security vulnerabilities that were previously patched for 64-bit and 32-bit architectures earlier this week.

The security advisory mentions a total of 21 security vulnerabilities fixed for linux-raspi2, the Linux kernel for Raspberry Pi 2 on Ubuntu 17.10 (Artful Aardvark) operating systems, including a race condition that could lead to a use-after-free vulnerability in Linux kernel's ALSA PCM subsystem, and a use-after-free vulnerability in the network namespaces implementation.

The update also addresses a race condition in Linux kernel's OCFS2 filesystem and loop block device implementations, as well as a null pointer dereference in the RDS (Reliable Datagram Sockets) protocol implementation. Most of these flaws could allow a local attacker to crash the vulnerable system by causing a denial of service or possibly execute arbitrary code.

Xubuntu Zesty Aardvark upgrade

Filed under
Ubuntu

The Xubuntu upgrade process worked rather well. First, I was able to work around the Zesty EOL quirks, and that's an important one, but I expect Ubuntu (and friends) to offer a seamless GUI mechanism. Users should not have to wonder how to get an upgrade underway. Then, the actual upgrade was successful, especially considering I had an UKUU kernel, lots of third-party repos, and that all of this runs in a complex eight-boot UEFI configuration.

Post boot, we had a single error, but nothing after that. Smooth sailing. Good performance, Meltdown and microcode stuff notwithstanding, good hardware support, lots of nice programs and sweet looks all over the place. Fewer niggles than with Kubuntu 17.10, meaning the dev teams had time to polish all those beta-quality rough edges that were unleashed onto unsuspecting users. This leaves my Xubuntu instance ready and waiting for the LTS in April. That will be an interesting experience, I'm sure. But if you're wondering, you can safely attempt to update, and by now, Aardvark has reached a usable state, so you will have none of those tribulations like I did when I tested early on. Oh me, the sacrificial goat lover of the Linux world. Commence, brave people!

Ubuntu: Ubuntu 18.04 Preparations

  • Ubuntu 18.04 Gives Nautilus a Striking New Look

    There’s a rather large visual change in Ubuntu 18.04 that I’ve only just noticed.

    It’s not because the change in question is subtle or easy to miss. It’s because I have only just booted up a copy of the Bionic Beaver thanks to the release of Ubuntu 18.04 beta 2.

  • Ubuntu Linux 18.04 LTS 'Bionic Beaver' Beta 2 now available

    Ubuntu Linux 18.04 "Bionic Beaver" is almost here -- it is due on April 26. In the interim, today, the second -- and final -- beta becomes available. Bionic Beaver is very significant, as it is an LTS version, meaning "Long Term Support." This is important to those that prefer stability to bleeding edge and don't want to deal with the hassle of upgrades. In other words, you can install 18.04 and be confident that it will be supported for 5 years. In comparison, non-LTS Ubuntu versions get a mere 9 months.

    There is plenty to be excited about with Ubuntu Linux 18.04 LTS 'Bionic Beaver' Beta 2, including the GNOME 3.28 desktop environment -- Beta 1 did not include GNOME at all. Of course, all the other DE flavors are available too, such as KDE and Xfce. The kernel is at 4.15, which while not the most current version, is still quite modern. Also included is LibreOffice 6.0 -- an essential tool that rivals Microsoft Office. Wayland is available as a technical preview, although X remains the default display server -- for now.

  • Ubuntu 18.04 Final Beta Available to Download

    USB thumb drives at the ready as the Ubuntu 18.04 beta download is now available for testing.

    This release marks the first official testing snapshot of what will become Ubuntu 18.04 LTS later this month.

  • Ubuntu 18.04 LTS Final Beta Released
  • Ubuntu Studio 18.04 Bionic Beaver Beta is released!

    The beta of the upcoming release of Ubuntu Studio 18.04 is ready for testing.

  • Ubuntu MATE 18.04 Beta 2

    We are preparing Ubuntu MATE 18.04 (Bionic Beaver) for distribution on April 26th, 2018 With this Beta pre-release, you can see what we are trying out in preparation for our next (stable) version.

  • Ubuntu 18.04 LTS (Bionic Beaver) Final Beta released

    The Ubuntu team is pleased to announce the final beta release of the
    Ubuntu 18.04 LTS Desktop, Server, and Cloud products.

    Codenamed "Bionic Beaver", 18.04 LTS continues Ubuntu's proud tradition
    of integrating the latest and greatest open source technologies into a
    high-quality, easy-to-use Linux distribution.  The team has been hard
    at work through this cycle, introducing new features and fixing bugs.

    This beta release includes images from not only the Ubuntu Desktop,
    Server, and Cloud products, but also the Kubuntu, Lubuntu, Ubuntu
    Budgie, UbuntuKylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu flavours.

    The beta images are known to be reasonably free of showstopper CD
    build or installer bugs, while representing a very recent snapshot of
    18.04 that should be representative of the features intended to ship
    with the final release expected on April 26th, 2018.

  • The Nextcloud Box: a review of building an IoT device with snaps

    In 2016, Canonical, Nextcloud and WDLabs introduced the Nextcloud Box, the first IoT style device running with snaps out of the box. Besides sales of nearly 2K boxes before Western Digital shut down their research division WDLabs late last year, the snap been extremely popular with some days hitting over 10,000 downloads. Its installed base is estimated to be over 8000, making it a popular way to run a private cloud. Read our guest blog by Nextcloud’s Jos Poortvliet on to learn more about Nextcloud, the Box and how snaps help thousands of Nextcloud users keep their data under their control.

Open Hardware: Good for Your Brand, Good for Your Bottom Line

Chip makers are starting to catch on to the advantages of open, however. SiFive has released an entirely open RISC-V development board. Its campaign on the Crowd Supply crowd-funding website very quickly raised more than $140,000 USD. The board itself is hailed as a game-changer in the world of hardware. Developments like these will ensure that it won't be long before the hardware equivalent of LEGO's bricks will soon be as open as the designs built using them. Read more
