I UPGRADED the operating system on my MacBook Air last week and I figured I ought to do the same on my Linux desktop.
Moving from Ubuntu 16.04 (Xenial Xerus) to 16.10 (Yakkety Yak) on my desktop PC was nowhere as quick and easy as it was to upgrade from OS X 10.11 to macOS 10.12, but the process was nonetheless pretty straightforward and relatively trouble-free.
While it took less than an hour to perform the upgrade on my Mac, it took several hours to download and install the latest version of Ubuntu.
Much has already been written about how Unity 8, the new converged interface being developed for mobile and desktop devices, again failed to make it to the latest version of Ubuntu—although a rough preview of it is built into Yakkety (just log out and choose Unity 8 in the log-in screen).
On the surface, Ubuntu 16.10 doesn’t look very different than previous releases, and its built-in Unity 7.5 interface features just minor improvements and a few bug fixes.
To find out what’s new about Ubuntu 16.10, you have to look inside.
I've stated for years how much I dislike Ubuntu's Unity interface. Yes, it's become more polished through the years, but it's just not an interface that thinks the same way I do. That's likely because I'm old and inflexible, but nevertheless, I've done everything I could to avoid using Unity, which usually means switching to Xubuntu. I actually really like Xubuntu, and the Xfce interface is close enough to the GNOME 2 look, that I hardly miss the way my laptop used to look before Unity.
I wasn't alone in my disdain for Ubuntu's flagship desktop manager switch, and many folks either switched to Xubuntu or moved to another Debian/Ubuntu-based distro like Linux Mint. The MATE desktop started as a hack, in fact, because GNOME 3 and Unity were such drastic changes. I never really got into MATE, however, because I thought it was going to be nothing more than a hack and eventually would be unusable due to old GNOME 2 libraries phasing out and so forth.
Founder Mark Shuttleworth announced the first public release of Ubuntu – version 4.10, or “Warty Warthog” – on Oct. 20, 2004. The idea behind what would become the most recognizable and widely used Linux distributions ever was simple – create a Linux operating system that anybody could use. Here’s a look back at Ubuntu’s history.
Yup, it’s twelve years to the day since Mark Shuttleworth sat down to tap out the first Ubuntu release announcement and herald in an era of “Linux for human beings”.
The de facto standard for Raspberry Pi operating systems is Raspbian–a Debian based distribution specifically for the diminutive computer. Of course, you have multiple choices and there might not be one best choice for every situation. It did catch our eye, however, that the RaspEX project released a workable Ubunutu 16.10 release for the Raspberry Pi 2 and 3.
RaspEX is a full Linux Desktop system with LXDE (a lightweight desktop environment) and many other useful programs. Firefox, Samba, and VNC4Server are present. You can use the Ubuntu repositories to install anything else you want. The system uses kernel 4.4.21. You can see a review of a much older version of RaspEX in the video below.
The Yakkety Yak 16.10 is released and now you can download the new wallpaper by clicking here. It’s the latest part of the set for the Ubuntu 2016 releases following Xenial Xerus. You can read about our wallpaper visual design process here.
We are delighted to announce the availability of a new service for Ubuntu which any user can enable on their current installations – the Canonical Livepatch Service.
This new live kernel patching service can be used on any Ubuntu 16.04 LTS system (using the generic Linux 4.4 kernel) to minimise unplanned downtime and maintain the highest levels of security.
Linux 4.0 introduced a wonderful feature for those that need insane up-time -- the ability to patch the kernel without rebooting the machine. While this is vital for servers, it can be beneficial to workstation users too. Believe it or not, some home users covet long up-time simply for fun -- bragging rights, and such.
If you are an Ubuntu 16.04 LTS user (with generic Linux kernel 4.4) and you want to take advantage of this exciting feature, I have good news -- it is now conveniently available for free! Unfortunately, this all-new Canonical Livepatch Service does have a catch -- it is limited to three machines per user. Of course, home users can register as many email addresses as they want, so it is easy to get more if needed. Businesses can pay for additional machines through Ubuntu Advantage. Want to give it a go? Read on.
"Since the release of the Linux 4.0 kernel about 18 months ago, users have been able to patch and update their kernel packages without rebooting. However, until now, no other Linux distribution has offered this feature for free to their users. That changes today with the release of the Canonical Livepatch Service", says Tom Callway, Director of Cloud Marketing, Canonical.
Earlier this week Canonical announced their Kernel Livepatching Service for Ubuntu 16.04 LTS users. Canonical's service is free for under three systems while another alternative for Ubuntu Linux users interested in a commercial service is CloudLinux's KernelCare.
The folks from CloudLinux wrote in to remind us of their kernel patching solution, which they've been offering since 2014 and believe is a superior solution to Canonical's service. KernelCare isn't limited to just Ubuntu 16.04 but also works with Ubuntu 14.04 and other distributions such as CentOS/RHEL, Debian, and other enterprise Linux distributions.
Today, October 20, 2016, Linux kernel maintainer Greg Kroah-Hartman announced three new maintenance updates for the Linux 4.8, 4.7, and 4.4 LTS kernel series, patching a major security vulnerability.
Known as "Dirty COW," the Linux kernel vulnerability documented at CVE-2016-5195 is, in fact, a nasty bug that could have allowed local users to write to any file they can read. The worst part is that the security flaw was present in various Linux kernel builds since at least the Linux 2.6.x series, which reached end of life in February this year.
As reported earlier, three new Linux kernel maintenance releases arrived for various Linux-based operating systems, patching a critical and ancient bug popularly known as "Dirty COW."
We already told you that the kernel vulnerability could be used by a local attacker to run programs as an administrator, and it looks like it also affects all supported Ubuntu releases, including Ubuntu 16.10 (Yakkety Yak), Ubuntu 16.04 LTS (Xenial Xerus), Ubuntu 14.04 LTS (Trusty Tahr), and Ubuntu 12.04 LTS (Precise Pangolin), as well as all of their official or unofficial derivatives running the same kernel builds.
Kernel live patching enables runtime correction of critical security
issues in your kernel without rebooting. It’s the best way to ensure
that machines are safe at the kernel level, while guaranteeing uptime,
especially for container hosts where a single machine may be running
thousands of different workloads.
We’re very pleased to announce that this new enterprise, commercial
service from Canonical will also be available free of charge to the
The Canonical Livepatch Service is an authenticated, encrypted, signed
stream of livepatch kernel modules for Ubuntu servers, virtual
machines and desktops.
