Ubuntu 18.10 (Cosmic Cuttlefish) Reached End of Life, Upgrade to Ubuntu 19.04

Dubbed Cosmic Cuttlefish by Canonical’s CEO Mark Shuttleworth, the Ubuntu 18.10 operating system was released last year on October 18th featuring the GNOME 3.30 desktop environment by default with a fresh new look and feel based on the in-house developed Yaru theme, formerly Communitheme. The system was using the Linux 4.18 kernel series. On July 19th, 2019, Canonical’s Adam Conrad announced in an email that Ubuntu 18.10 (Cosmic Cuttlefish) has reached end of life nine months after its initial release, and that no package updates will be allowed in the software repositories after July 18th, which will be archived and kept for historical purposes for a few more months.
