Let me upgrade that for you, for only 9.99 Tux. Behold, an article about the Kubuntu upgrade experience and results going from 17.10 Artful Aardvark to 18.08 Bionic Beaver on two different laptops - multi-boot Windows-and-Linux BIOS/Nvidia graphics and UEFI/Intel graphics setups, including third-party repo management, drivers, boot times, fonts, resources, performance, various inconsistencies and problems, and more. Enjoy.
