For people who don't know Ubuntu is a distro of Linux a OS for PC's its free to download. But any way every 6 months a new version of Ubuntu comes out 17.04 will be release in April called Zesty Zapus then in October it will restart its naming convention with A so in October 2018 the letter C will be up and as you can see https://wiki.ubuntu.com/DevelopmentCodeNames#C Cheshire Cat is a possible name. Heres hoping the devs over at Ubuntu hear about this thread and consider Cheshire Cat as its name for Ubuntu 18.10 after Blink-182's for Album in 1995
