Do I need to upgrade my PHP 7.2 to 7.4 in order to keep getting security updates for PHP if I'm running Ubuntu 18.04 LTS? I know that 18.04 is supported until April of 2023, but PHP 7.2 goes out of support in November of 2020. Does Canonical keep releasing security updates for PHP 7.2 for the entire EOL of Ubuntu 18.04?

The Ubuntu Security Team will continue to patch high-priority security vulnerabilities in the Ubuntu 18.04 -main repository pocket until 2028.
- The
phppackage in Ubuntu 18.04 is in the -main pocket, so it's covered. - 18.04 community support ends in 2023.
- ESM (2023-2028) is security ONLY. No community technical support.
They won't patch ALL reported vulnerabilities; they prioritize.
They will patch common packages in -universe, those are available only to Ubuntu Pro subscribers.
Security patches won't protect any non-Ubuntu versions that you install.
