The KDE neon distribution mixes a stable Ubuntu base with cutting-edge packages of the KDE Plasma desktop environment. The KDE neon team is dropping support for versions of its distribution that are based on Ubuntu 16.04 in order to streamline maintenance. "Upgrades to 18.04 are working well but maintaining twice as many builds as normal is taking its toll on our time and team of guinea pig packagers. Neon on 16.04 (xenial) base will reach End of Life on Monday [October 22, 2018]. Please update to 18.04 base to continue receiving updates."
