Ubuntu offers a service called Ubuntu Pro that allows home users to extend support for Ubuntu 20.04 at no cost through Extended Security Maintenance (ESM), providing a decade of vulnerability management for critical, high, and select medium security issues. Ubuntu 20.04, launched in 2020, has five years of support remaining. Users can create a free Ubuntu Pro account to link their operating system to ESM, which can be done by executing the command "sudo pro attach TOKEN" after obtaining a unique token from their account. ESM is available for all Long Term Support (LTS) versions of Ubuntu, including 20.04, 22.04, and 24.04, with support lasting until 2030, 2032, and 2034, respectively.
