Cosmic Cuttlefish is the Ubuntu codename for version 18.10 of the Ubuntu Linux-based operating system. Officially released on October 18, 2018, Cosmic Cuttlefish follows the Bionic Beaver (v18.04) release.
Unlike Bionic Beaver, which was a Long-Term Support (LTS) release designed to be supported for five years, Cosmic Cuttlefish will only be supported for nine months. As a result, the Ubuntu 18.10 Cosmic Cuttlefish release will be supported through July 2019, while Bionic Beaver will continue to be supported until April 2023.
