Canonical on Thursday released Ubuntu Linux 18.04, which utilizes live patching and a new metric data collection system. Notably missing is the Unity desktop that had distinguished the distro but was poorly received. Canonical last year made the switch from Unity 7 to upstream GNOME as Ubuntu’s default desktop environment. Unity is not an option in Ubuntu 18.04 and will not be available in desktop offerings moving forward. “The overall response was positive,” said Will Cooke, engineering director for desktop at Canonical.
