Ubuntu version history#Ubuntu 17.10 (Artful Aardvark)

After each version of Ubuntu has reached its end-of-life time, its repositories are removed from the main Ubuntu servers and consequently the mirrors.{{Cite mailing list |url=https://lists.ubuntu.com/archives/ubuntu-mirrors-announce/2007-May/000010.html |title=Old packages from unsupported Ubuntu releases will be removed from archive.ubuntu.com |last=Moffitt |first=Nick |mailing-list=ubuntu-mirrors-announce |date=31 May 2007 |access-date=1 December 2008}} Older versions of Ubuntu repositories and releases can be found on the old Ubuntu releases website.{{Cite web |url=http://releases.ubuntu.com/ |title=Ubuntu Releases |publisher=Ubuntu |access-date=11 August 2008}}{{Cite web|url=http://old-releases.ubuntu.com/releases/ |title=Old Ubuntu Releases |publisher=Old-releases.ubuntu.com |access-date=17 July 2013}}

Ubuntu releases are also given code names, using an adjective and an animal with the same first letter{{snd}}an alliteration{{snd}}e.g., "Dapper Drake". With the exception of the first two releases, code names are in alphabetical order, and except for the first three releases, the first letters are sequential, allowing a quick determination of which release is newer. As of Ubuntu 17.10, however, the initial letter "rolled over" and returned to "A". Names are occasionally chosen so that animal appearance or habits reflects some new feature, e.g., "Koala's favourite leaf is Eucalyptus"; see {{slink||Ubuntu 9.10 (Karmic Koala)}}. Ubuntu releases are often referred to using only the adjective portion of the code name, e.g., "Feisty".{{Cite web |url=https://wiki.ubuntu.com/DevelopmentCodeNames |title=DevelopmentCodeNames |work=Ubuntu Team Wiki |publisher=Canonical Ltd. |access-date=8 May 2009}}

On 4 March 2010 it was announced that Lucid Lynx would feature a new theme, including new logos, taking Ubuntu's new visual style into account:{{Cite web |url=https://wiki.ubuntu.com/Brand#Light:%20Ubuntu%20is%20Lightware |title=Light: Ubuntu is Lightware |publisher=ubuntu.com |access-date=4 March 2010 |archive-url=https://web.archive.org/web/20220523203914/https://wiki.ubuntu.com/Brand#Light:%20Ubuntu%20is%20Lightware|archive-date=2022-05-23|url-status=dead}}

{{Blockquote | The new style in Ubuntu is inspired by the idea of "Light".

We're drawn to Light, because it denotes both warmth and clarity, and intrigued by the idea that "light" is a good value in software. Good software is "light" in the sense that it uses your resources efficiently, runs quickly, and can easily be reshaped as needed. Ubuntu represents a break with the bloatware of proprietary operating systems and an opportunity to delight to those who use computers for work and play. More and more of our communications are powered by light, and in future, our processing power will depend on our ability to work with light, too.

Visually, light is beautiful, light is ethereal, light brings clarity and comfort.

Historical perspective: From 2004–2010, the theme in Ubuntu was "Human". Our tagline was "Linux for Human Beings" and we used a palette reflective of the full range of humanity. Our focus as a project was bringing Linux from the data center into the lives of our friends and global family.

The new theme met with mixed critical responses. Ars Technica's Ryan Paul said: "The new themes and updated color palette are nice improvement for Ubuntu ... After testing the new theme for several hours, I feel like it's a step forward, but it still falls a bit short of my expectations." One aspect of controversy from the new design was the placement of the window-control buttons on the left instead of on the right side of the windows.{{Cite web |url=https://arstechnica.com/open-source/reviews/2010/03/hands-on-a-close-look-at-ubuntus-new-non-brown-theme.ars |title=Hands-on: a close look at Ubuntu's new non-brown theme |access-date=8 March 2010 |last=Paul |first=Ryan |date=5 March 2010}}{{Cite web |url=https://arstechnica.com/open-source/news/2010/03/ubuntu-dumps-the-brown-introduces-new-theme.ars |title=Ubuntu dumps the brown, introduces new theme and branding |access-date=8 March 2010 |last=Paul |first=Ryan |date=March 2010}} TechSource's Jun Auza expressed concern that the new theme was too close to that used by Apple's Mac OS X: "I think Ubuntu is having an identity crisis right now and should seriously consider changing several things in terms of look and feel to avoid being branded as a Mac OS X rip-off, or worse, get sued by Apple. I believe the fans are divided right now. Some have learned to love the brown color scheme since it uniquely represents Ubuntu, while others wanted change."{{Cite web |url=http://www.junauza.com/2010/03/ubuntus-new-look-pale-imitation-of-mac.html |title=Ubuntu's New Look, a Pale Imitation of Mac OS X? |access-date=8 March 2010 |last=Auza |first=Jun |date=March 2010}}

The naming of Ubuntu 11.10 (Oneiric Ocelot) was announced on 7 March 2011 by Mark Shuttleworth. He explained that Oneiric means "dreamy".{{Cite web|url=http://www.markshuttleworth.com/archives/646|title=Next after Natty?|access-date=9 September 2011|last=Shuttleworth|first=Mark|date=March 2011}} Ubuntu 11.10 was released on 13 October 2011.

In April 2011, Shuttleworth announced that Ubuntu 11.10 would not include the classic GNOME desktop as a fall back to Unity. Instead, 11.10 included a 2D version of Unity as a fallback for computers that lacked the hardware resources for the Compiz-based 3D version. Shuttleworth also confirmed that Unity in Ubuntu 11.10 would run as a shell for GNOME 3 on top of GNOME 3 libraries, unlike in Ubuntu 11.04 where it ran as a shell for GNOME 2. Meanwhile, users were able to install the entire GNOME 3 stack along with GNOME Shell directly from the Ubuntu repositories.{{Cite web|url=http://www.markshuttleworth.com/archives/669|title=Celebrating Gnome 3.0|author=Mark Shuttleworth}} During the development cycle there were many changes to Unity, including the placement of the Ubuntu button on the left Launcher instead of on the top Panel, the autohiding of the window controls (and the global menu) on maximized windows, and the introduction of window controls and more transparency into the Dash search utility.{{Cite web|url=http://www.markshuttleworth.com/archives/717|title=Dash takes shape for 11.10 Unity|date=16 August 2011|publisher=Mark Shuttleworth|access-date=21 October 2011}}

Jesse Smith of DistroWatch reviewed that while many people had questioned Ubuntu's direction, he felt that the "puzzle pieces, which may have been underwhelming individually, have come together to form a whole, clear picture."

Experimental support for the ZFS filesystem is now available from the installer. NVIDIA-specific improvements were made. Proprietary Nvidia graphics drivers are now bundled with the installer in place of the open-source Nouveau drivers. Support for the Raspberry Pi 4 platform was added. The installation media now uses LZ4 compression which, compared to the previously used compression algorithm, gzip, offers faster installation times. This was decided following benchmarking of a variety of compression algorithms conducted by the Ubuntu kernel team.{{cite web|url=https://smackerelofopinion.blogspot.com/2019/09/boot-speed-improvements-for-ubuntu-1910.html?m=1|title=Boot speed improvements for Ubuntu 19.10 Eoan Ermine|access-date=17 October 2019|date=10 September 2019}}{{cite web| url=https://kernel.ubuntu.com/~cking/boot-speed-eoan-5.3/kernel-compression-method.txt| title=Comparison of Kernel Compression Methods (x86)| access-date=17 October 2019| archive-date=17 October 2019| archive-url=https://web.archive.org/web/20191017194258/https://kernel.ubuntu.com/~cking/boot-speed-eoan-5.3/kernel-compression-method.txt| url-status=dead}} Kernel load and decompression times were tested and LZ4 was found to offer decompression as much as seven times faster.

I think the launch of Ubuntu 22.04 is a clear sign Canonical is much more interested in publishing releases on a set schedule than producing something worthwhile. This version was not ready for release and it is probably going to be a costly endeavour to maintain this collection of mixed versioned software and mixed display server and mixed designs for a full five years. It's a platform I would recommend avoiding.

Nautilus, the file manager, has received several quality-of-life features, and Wi-Fi settings now include an option to generate a QR code for network credentials. Notifications now include a header for the sender app's name, settings have been reorganized, touch users now tap to click by default, and users can now log in from a remote desktop.{{Citation |title=Introducing GNOME 46, "Kathmandu" |date=2024-03-20 |url=https://release.gnome.org/46/ |access-date=2024-04-25 |publisher=GNOME |language=en}}

Cheese, a Photo Booth-like camera app, has been replaced by GNOME Snapshot in the extended install, and GNOME Games is now never bundled on install. Thunderbird is now provided as only its snap version.

Abishek of It's Foss News strongly criticized the LTS release for not changing behavior from 23.10, the last release, that by default made users unable to graphically install .deb packages, the most popular format for distributing software. Combined with the App Center, a recommended application to open the package with, freezing when attempting to open a .deb file, along with .deb's being opened with the archive extractor by default in 20.04, he argued that this was indicative of Canonical resorting to sabotaging user experience to promote their own products—in this case, snap packages. Conversely, It's Foss praised other aspects of the release as "a near-perfect upgrade". By July 15, the App Center received the ability to install .deb packages (while providing a warning), though they still cannot be managed even if installed from the App Center's store.{{Citation |last=Ankush |first=Das |title=Ubuntu 24.04 LTS Can Now Do What It Should Have Always Done |date=2024-07-15 |work=It's FOSS News |url=https://news.itsfoss.com/ubuntu-24-04-deb-install/ |access-date=2024-09-05 |language=en}}
