Three or five or more? I've written an article explaining the system update and security implications for Kubuntu 22.04 LTS past the April 2025 three-year support date, including inaccurate upgrade notification popup, apt architecture overview, third-party repositories, snaps, other software sources, Expanded Security Maintenance pro offering, essential differences between Ubuntu and Kubuntu, practical examples from previous releases, some other tips and tricks, and more. Enjoy.
