Canonical extends the life cycle of Ubuntu 14.04 and 16.04 from eight to ten years. Originally, the Linux distributions were to receive ESM support (Extended Security Maintenance) with security updates and kernel live patches by April 2022 or 2024. Now companies have until 2024 or 2026 to replace their aging systems with Trusty Tahr and Xenial Xerus.
Nothing will change for Ubuntu 18.04 and 20.04: Canonical has already been providing updates to the distributions released in April 2018 and 2020 for ten years. The step justifies the provider with the IT budgets: These have been increased significantly in the past three years, now customers can distribute their infrastructure upgrades more economically over longer periods of time.
