Ubuntu 17.10, code named Artful Aardvark; I guess you already know that Artful means full of art or skill. And Aardvark is a medium-sized, burrowing, nocturnal mammal native to Africa. Colloquially, it is called African Ant Eater.
Nowadays Ubuntu become the world’s most popular desktop Linux operating system, and with its latest short-term support release, it’s clear Canonical want to keep a firm grip on the title.
As release with Artful Aardvark (Ubuntu 17.10) in October 19, 2017 Canonical continues Ubuntu’s proud tradition of integrating the latest and greatest open source technology into a high-quality, easy-to-use Linux distribution. Ubuntu 17.10 Artful Aardvark marks an all-new chapter in Ubuntu’s already rich history. As always, the team has been hard at work through this cycle, introducing new features and fixing bugs.
This is the first version of Ubuntu to use GNOME Shell as the default desktop. ‘The HUD, global menu, and other Unity features are no longer included’. By choosing to drop Unity most of Ubuntu’s home-grown usability efforts also fall by the wayside.
In Unity’s place comes a bespoke version of GNOME Shell that is ‘customized’ to resemble something that’s superficially close to the Unity desktop layout. The Ubuntu 17.10 desktop uses a two-panel layout: a full-height vertical dock sits on the left-hand side of the screen, while a ‘top bar’ is stripped across the top.
The top bar plays host a new type of app menu, a calendar applet/message tray, app indicators, and a unified status menu for managing network, volume, Bluetooth and user sessions.
The new Ubuntu Dock is both a task manager and an application launcher. It shows icons for open and running software windows as well as ‘pinned’ launchers for user’s favorite apps.
The dock is also global; it displays icons/applications from all workspaces regardless of which one user is actually viewing.
Both the Ubuntu Dock and the top bar are semi-transparent, which adds nice visual presence. When a window touches either element the “dynamic transparency” feature kicks in to render both dock and top bar darker, making panel label contents more legible in the foreground.
The main “desktop” area remains a usable space on which user can place icons, folders and files.
Though there’s no longer a true global app menu, but the majority of apps place a small menu in the top bar bearing the name of the app in focus. These app menus contain a solitary ‘quit’ button at the least, or a full complement of options at most.
Workspaces are a common feature found on most modern desktop operating systems including Windows 10, so it’s a good thing that Ubuntu hasn’t ditched them. User can easily move windows between workspaces by clicking on a window and moving it on over the workspace.
In Ubuntu 17.10 Applications are listed alphabetically, ordered into scrollable pages. User can launch an application by clicking on it, selecting it with keyboard arrow keys and pressing enter, or by touching it.
After years of ‘footnote’ releases that brought only minor tweaks, the ‘Artful Aardvark’ brings all-out with change, ready to usher in the new era. Under the hood, there have been updates to many core packages, including a new 4.13-based kernel, glibc 2.26, gcc 7.2, and much more in Ubuntu Desktop. Let’s have a brief list view on some of those updates.
Note: Install gnome-session and choose GNOME from the cog on the login screen if user would like to try a more upstream version of GNOME. If any user’ d like to also install more core apps, he’d install the vanilla-gnome-desktop met package.
Not only the Ubuntu 17.10 Desktop but also, there are significant changes into the Ubuntu 17.10 Server version too. For the Ubuntu Server 17.10, the OS Version for the printing server has been increased to announce Windows Server 2003 R2 SP2 ID mapping checks added to the testparm(1) tool. There are some ID mapping backends too, which are not allowed to be used for the default backend. Winbind will no longer start if an invalid backend is configured as the default backend. The others are as follows,
Qemu has been updated to the 2.10 release. Since the last version was 2.8.
Among many other changes there is one that might need follow on activity by the user/admin: Image locking is added and enabled by default. This generally makes execution much safer, but can break some old use cases that now explicitly have to opt-in to ignore/share the locks by tools and subcommands using the –force-share option or the share-rw dqev property.
Libvirt has been updated to version 3.6.
LXD was updated to version 2.18. Some of the top new features of LXD 2.18 are:
Ubuntu 17.10 includes the latest release of DPDK that has stable updates: 17.05.2. This made it possible to integrate Open vSwitch 2.8.
Open vSwitch has been updated to 2.8. Though user need to specify dpdk devices via dpdk-devargs.
The DNS server BIND9 was updated to include the new Key Signing Key (KSK) that was published on July 11, 2017. Starting on October 11, 2017, that key will sign the root zone key, which in turn is used to sign the actual root zones.
The cloud-init version was updated to 17.1. Notable new features for cloud-init are as follows,
The Curtin version is updated to ‘0.1.0~bzr519-0ubuntu1’. New features are:
Samba is updated to version 4.6.7. Important changes in the 4.6.x series are:
There are many other changes too. We recommend that all users read the release notes, which document caveats, workarounds for known issues, as well as more in-depth Release Notes.
Users of Ubuntu 17.04 will be offered an automatic upgrade to 17.10. As always, upgrades to the latest version of Ubuntu are entirely free of charge.
Remember, here at eRacks, we offer pre-installed Ubuntu 17.10 Artful Aardvark with our new systems either directly from the OS dropdown, or by custom quote.

Fedora (formerly Fedora Core) is a Unix-like operating system based on the Linux kernel and GNU programs (a Linux distribution), developed by the community-supported Fedora Project and sponsored by the Red Hat company. Fedora contains software distributed under various free and open-source licenses and aims to be on the leading edge of such technologies. Fedora is the upstream source of the commercial Red Hat Enterprise Linux distribution.
Since the release of Fedora 21, three different editions are available: Workstation, focused on the personal computer, Server and Cloud for servers, and Atomic being the edition meant for cloud computing. As released on July, 11, 2017 they introduced Fedora 26!
Fedora 26 has arrived with thousands of improvements to development tools, partitioning tools, better caching of user and group information, better debugging, an improved DNF package manager, and so much more.
Let’s see some of many upgraded System Requirements & features, those are new Fedora 26 offering.
Fedora 26 provides software to suit a wide variety of applications. The storage, memory and processing requirements vary depending on usage. For example, a high traffic database server requires much more memory and storage than a business desktop, which in turn has higher requirements than a single-purpose virtual machine. Your requirements may differ, and most applications will benefit from more than the minimum resources.
Fedora 26 recommended minimum System Configuration for the default installation are as follows:
Fedora 26 can be installed and used on systems with limited resources. Text, VNC, or kickstart installations are advised over graphical installation for systems with very low memory. Larger package sets require more memory during installation, so users with less than 768MB of system memory may have better results preforming a minimal install and adding to it afterward.
For best results on systems with less than 1GB of memory, one should use the DVD installation image. Fedora also give us some guidelines for it’s best practices and performances.
Graphical installation of Fedora requires a minimum screen resolution of 800×600. Owners of devices with lower resolution, such as some netbooks, should use text or VNC installation. Once installed, Fedora will support these lower resolution devices. The minimum resolution requirement applies only to graphical installation.
Fedora 26 supports most display adapters. Modern, feature-rich desktop environments like GNOME3 and KDE Plasma Workspaces use video devices to provide 3D-accelerated desktops. Systems with older or no graphics acceleration devices can have accelerated desktop environments using LLVMpipe technology, which uses the CPU to render graphics. LLVMpipe requires a processor with SSE2.
Fedora 26 offers latest GNOME 3.24, LibreOffice 5.3, Fedora Media Writer, Improved Qt app compatibility & so on…
Newest version of the GNOME desktop now has a Natural Light Filter feature that changes display’s color temperature. It works based on the time of day and helps prevent sleeplessness and eye strain. Also, there are updates to the Settings panel for online accounts, printers, and users. The notifications area sports a cleaner, simpler layout, with integrated weather information.
For developers, Builder now features improved support for systems like Flatpak, CMake, Meson, and Rust. It also integrates Valgrind to help profile your project. There are numerous other improvements, which you can find in the GNOME 3.24 release notes.
The latest version of the popular office suite features many changes. It includes a preview of the experimental new NotebookBar UI. There’s also a new internal text layout engine to ensure consistent text layout on all platforms.
The new version of the Fedora Media Writer can create bootable SD cards with Fedora for ARM devices such as Raspberry Pi. It also features better support for Windows 7 and screenshot handling. The utility also notifies you when a new release of Fedora is available.
The Adwaita theme contains many improvements and looks closer to its GTK counterpart than ever. There are also two variants ported to Qt, dark and high contrast. If you switch to dark or high contrast Adwaita, your Qt apps will switch as well.
Matthew Miller, Fedora Project Leader, wrote in a Fedora Magazine post about Fedora 26. As he wrote “First, of course, we have thousands of improvements from the various upstream software we integrate, including new development tools like GCC 7, Golang 1.8, and Python 3.6. We’ve added a new partitioning tool to Anaconda (the Fedora installer) — the existing workflow is great for non-experts, but this option will be appreciated by enthusiasts and sysadmins who like to build up their storage scheme from basic building blocks. F26 also has many under-the-hood improvements, like better caching of user and group info and better handling of debug information. And the DNF package manager is at a new major version (2.5), bringing many new features. Really, there’s new stuff everywhere — read more in the release notes.”
Among the current Fedora users, most of may wish to go straight for the clean install—which makes perfect sense and always winds up with a reliable and stable instance.
As with release of latest version of Fedora, we offer latest Fedora 26 with our systems as pre-configured according to your custom quote…
