I don't really understand Debian LTS, I know they more recently, meaning maybe in the last 5 years, talked about increasing the support cycle, but if I go to https://wiki.debian.org/LTS https://wiki.debian.org/LTS it says "current LTS supported until 2024, future LTS supported to 2026. There is then some "Extended LTS" that has further support, saying "adding another 5 years to the existing 5 years", which is commercial and probably something I'm not going to be able to sell over using Ubuntu LTS.
