Ubuntu 18.04 LTS will use GNOME as its default desktop environment, and not Unity 8 — or even Unity 7.
In an extraordinary blog post that I have yet to fully digest, Mark Shuttleworth has announced that Canonical is to end its investment in Unity 8, Mir, Ubuntu for phones and tablets, and will no longer pursue its goal of “convergence”.
‘we will end our investment in Unity 8, the phone and convergence shell’
In a further striking admission Ubuntu’s founder adds that the Ubuntu desktop will ‘shift back to GNOME for Ubuntu 18.04 LTS.’
“We will continue to produce the most usable open source desktop in the world, to maintain the existing LTS releases, to work with our commercial partners to distribute that desktop, to support our corporate customers who rely on it, and to delight the millions of IoT and cloud developers who innovate on top of it,” he says.
Despite the blunt about turn in developing technologies and projects that have dominated the project over the past few years Shuttleworth reaffirms Canonical’s “ongoing passion for, investment in, and commitment to, the Ubuntu desktop that millions rely on.”
All current LTS releases will continue to be maintained and supported as expected going forward. The Unity 7 desktop has been in maintenance mode for several years.
But on the diversion into the mobile space the Ubuntu founder is more pragmatic.
