In April 2017, it was announced that 17.04 would be the last release. The distribution was to be discontinued in favor of the standard Ubuntu distribution, which switched from using Unity to GNOME Shell as its desktop environment starting with its 17.10 release.
History
The project began as an unofficial "remix" because some users preferred the GNOME 3 desktop environment over Unity.[3] Ubuntu GNOME 12.10 Quantal Quetzal was the first stable version, released on 18 October 2012.[4]
Writing in October 2013, Jim Lynch stated:
"Ubuntu GNOME 13.10 will be welcomed by GNOME fans. GNOME 3.8 adds some significant new features that enhance the desktop experience, and all of it has been combined well with Ubuntu 13.10 itself. So the end result will probably be quite appealing for those who want Ubuntu, but with GNOME 3.8 instead of Unity. If you are not a fan of GNOME 3 then Lubuntu, Kubuntu or Xubuntu are much better desktop environments if you need to stay within the Ubuntu family. If none of those appeal to you then you might want to just sit tight and wait for Linux Mint 16 to arrive."[5]
Jim Lynch reviewed Ubuntu GNOME 14.04 LTS again in April 2014 and concluded:
"I have seen some reviews of regular Ubuntu 14.04 that have proclaimed it to be "the best version of Ubuntu yet" and that sort of thing. Well, I think it's fair to say that Ubuntu GNOME 14.04 may also be the finest version of Ubuntu GNOME as well, and that's something that the Ubuntu GNOME developers and users can take pride in."[6]
On 5 April 2017, Canonical Executive Chairman and Ubuntu founder Mark Shuttleworth announced that the mainline version of Ubuntu would move from Unity to the GNOME 3 desktop starting by version 18.04 LTS, which would make it virtually identical to Ubuntu GNOME.[7][8] It was later revealed that Ubuntu 17.10 would in fact be the first version to use GNOME.[9]
Shuttleworth wrote on 8 April 2017, "We will invest in Ubuntu GNOME with the intent of delivering a fantastic all-GNOME desktop. We're helping the Ubuntu GNOME team, not creating something different or competitive with that effort. While I am passionate about the design ideas in Unity and hope GNOME may be more open to them now, I think we should respect the GNOME design leadership by delivering GNOME the way GNOME wants it delivered. Our role in that, as usual, will be to make sure that upgrades, integration, security, performance and the full experience are fantastic."[10]
In light of Ubuntu's announcement that it would switch desktop environments from Unity to GNOME, the Ubuntu GNOME developers announced on 13 April 2017 that the distribution would merge into the mainline Ubuntu, starting with the 17.10 release.[11]
