The Canonical has released Ubuntu 22.04 on 21 April 2022. Ubuntu OS distribution is presently the most popular OpenSource GNU GPL software across the Globe. Ubuntu 22.04 is a Long-Term Support (LTS) release and will receive ongoing app updates and critical security fixes for five years from release. New Linux kernel releases and graphics driver updates are also rolled out as software updates every six months or so.
While overall support for Ubuntu 22.04 ends in 2027 it is likely that Extended Support Maintenance (ESM) will offer updates for a further three to five years. ESM updates aren’t automatic and do require you to enrol your computer in for Ubuntu Advantage/Ubuntu Pro (which is free for home users).
