Ubuntu Pro is a subscription offering for Ubuntu users who want to pay for the assurance of getting quick and high-quality security updates for Ubuntu. I tested it out to see how it works in practice, and to evaluate how well it works as a commercial open source service model for Linux.\n
Ubuntu Pro gives you 5 more years of security updates for versions that are EoL. You can see it here if you scroll down to the maintenance schedule https://ubuntu.com/security/esm
Glad to hear it’s extended maintenance for old software and not making their private users less secure.
