The Ubuntu 18.10 Linux release became generally available on Oct 18, providing new capabilities for desktop, server and cloud users.
On the desktop there is a new theme called “Yaru” that provides a different look and feel than what was provided by default in the prior 18.04 LTS release. Unlike 18.04, the 18.10 update is not a Long Term Support (LTS) release and will not get five years of support, instead it will only have nine months of support.
