'''Kubuntu''' ({{IPAc-en|k|ʊ|ˈ|b|ʊ|n|t|uː}} {{Respell|kuu|BUUN|too}})<ref name=:0>{{Cite web|url=https://www.ubuntu.com/about|title=About the Ubuntu project|last=Canonical|website=www.ubuntu.com|access-date=1 May 2018}}</ref><!--"oǒ'boǒntoō" is a modified AHD notation, see [[Phonetic notation of the American Heritage Dictionary]]--> is an official flavor of the [[Ubuntu]] [[operating system]] that uses the [[KDE Plasma Desktop | KDE Plasma Desktop Environment]] instead of the [[GNOME]] desktop environment. As part of the Ubuntu project, Kubuntu uses the same underlying systems. Kubuntu shares the same repositories as Ubuntu<ref>{{cite web|url=http://www.kubuntu.org/faq.php#fork|title=Is Kubuntu a fork?|archive-url=https://web.archive.org/web/20080307181806/http://www.kubuntu.org/faq.php|archive-date=2008-03-07|url-status=dead}}</ref> and is released regularly on the same schedule as Ubuntu.<ref>{{cite web|url=https://community.kde.org/Kubuntu|title=KDE Community Wiki|website=Kubuntu|date=22 March 2020|access-date=9 December 2020}}</ref>

Kubuntu was sponsored by [[Canonical Ltd.]] until 2012, and then directly by [[Blue Systems]]. Now, employees of Blue Systems contribute upstream to [[KDE]] and [[Debian]], and Kubuntu development is led by community contributors. During the changeover, Kubuntu retained the use of Ubuntu project servers and existing developers.<ref>{{cite news|url=https://www.wired.com/wiredenterprise/2012/04/kubuntu-blue-systems|title=Kubuntu Linux Gets New Sugar Daddy|magazine=Wired|first=Caleb|last=Garling|date=2012-04-11}}</ref>

==Name==
"Kubuntu" is a registered trademark held by Canonical.<ref>{{cite web|url=https://www.ipo.gov.uk/tmcase/Results/4/EU004541661|title=Trade Mark Number EU004541661|website=IPO.gov.uk|publisher=[[Intellectual Property Office (United Kingdom)|Intellectual Property Office]]|date=2006-05-18|access-date=2020-12-09}}</ref> It is derived from the name ''Ubuntu'', prefixing a ''K'' to represent the KDE platform that Kubuntu is built upon (following a widespread naming convention of prefixing ''K'' to the name of any software released for use on KDE platforms), as well as the KDE community.

{{Lang|bnt|[[Ubuntu philosophy|Ubuntu]]}} is a [[Bantu languages|Bantu]] term translating roughly to 'humanity'. Since Bantu grammar involves prefixes to form [[noun classes]], and the prefix {{Lang|bem|ku-}} has the meaning 'toward' in [[Bemba language|Bemba]], {{Lang|bem|kubuntu}} is therefore also a meaningful Bemba word or phrase translating to 'toward humanity'. Reportedly, the same word, by coincidence, also takes the meaning of 'free' (in the sense of '[[Gratis versus libre|without payment]]') in [[Kirundi]].<ref>{{cite web|url=http://www.kubuntu.org/faq.php#kubuntumeaning|title=Meaning of Kubuntu|archive-url=https://web.archive.org/web/20080307181806/http://www.kubuntu.org/faq.php|archive-date=2008-03-07|url-status=dead}}</ref>

==History==
Development started back in December 2004 at the Ubuntu Mataró Conference in [[Mataró]], [[Spain]]<ref>{{cite web|url=https://wiki.ubuntu.com/MataroConference|title=Kubuntu Birthdate|publisher=Ubuntu|access-date=2004-12-10}}</ref> when a Canonical employee Andreas Mueller, from Gnoppix, had the idea to make an Ubuntu KDE variant and got the approval from [[Mark Shuttleworth]] to start the first Ubuntu variant, called Kubuntu. On the same evening Chris Halls from the [[OpenOffice.org]] project and Jonathan Riddell from KDE started volunteering on the newborn project.

Shortly after Ubuntu was started, [[Mark Shuttleworth]] stated in an interview that he recognized the need for the KDE-based distribution in order to maintain diversity in Linux distributions, which in his belief aligns with Ubuntu project's overall purpose of increasing the adoption of free software.<ref>{{cite web|date=2006-04-26|title=Mark Shuttleworth on the Future of Kubuntu|url=https://lwn.net/Articles/181465|access-date=2013-09-23|website=LWN.net}}</ref>

[[K Desktop Environment 3]] was used as default interface until Kubuntu 8.04. That version included [[KDE Plasma Desktop]] as unsupported option which became default in the subsequent release, 8.10.<ref>{{cite web|url=http://www.kubuntu.org/news/8.10-release|title=8.10 Refreshes the Desktop|publisher=Kubuntu|date=2008-10-30|access-date=2013-09-23|archive-url=https://web.archive.org/web/20150703152517/http://www.kubuntu.org/news/8.10-release|archive-date=3 July 2015|url-status=dead}}</ref>

On {{Start date|2012|02|06}}, Canonical employee Jonathan Riddell announced the end of Canonical's Kubuntu sponsorship.<ref>{{cite web|url=https://lists.ubuntu.com/archives/kubuntu-devel/2012-February/005782.html|title=Kubuntu Status|website=Lists.Ubuntu.com|date=February 6, 2012|access-date=2013-09-23}}</ref> On {{Start date|2012|04|10}}, [[Blue Systems]] was announced on the Kubuntu website as the new sponsor.<ref name=BlueSponsor/> As a result, both developers employed by Canonical to work on Kubuntu–Jonathan Riddell and Aurélien Gâteau–transferred to Blue Systems.<ref>{{cite web|url=http://agateau.com/2012/04/11/into-the-blue|title=Into the blue|website=Agateau.com|date=2012-04-11|access-date=2013-09-23}}</ref>

Since 2019, Kubuntu has partnered with MindShare Inc. to offer "Kubuntu Focus" laptops and mini-PCs optimized and supported specifically for the LTS releases.<ref>{{cite web|url=https://kfocus.org/|title=Kubuntu Focus|website=kfocus.org|date=February 15, 2024|access-date=2024-02-15}}</ref>

==Releases==
Kubuntu follows the same naming/versioning system as Ubuntu, with each release having a code name and a version number (based on the year and month of release). Canonical provides support and security updates for Kubuntu components that are shared with Ubuntu for 18 months – five years in case of [[long-term support]] (LTS) versions – after release.<ref>{{cite web|url=http://www.ubuntu.com/business/desktop|title=Ubuntu – Desktop for Business|access-date=2012-05-26}}</ref> Both a [[Live CD|desktop]] version and an alternative (installation) version (for the [[x86]] and [[AMD64]] platforms) are available. Kubuntu CDs were also available through the ShipIt service (which was discontinued as of April 2011).<ref>{{cite web|url=https://shipit.kubuntu.org|title=ShipIt Kubuntu|archive-url=https://web.archive.org/web/20101212162154/https://shipit.kubuntu.org|archive-date=2010-12-12}}</ref>
