Ubuntu 18.04 Extended Security Maintenance

Canonical provides Extended Security Maintenance (ESM) for Ubuntu 18.04 LTS. The support lifecycle of ESM is tracked on the releases page in the Ubuntu Project documentation.

What's covered with ESM (Ubuntu Pro Infra-Only)?

During the lifetime of an Ubuntu release, Canonical provides security maintenance. Basic Security Maintenance covers binary packages that reside in the 'main' and 'restricted' components of the Ubuntu archive, as well as Linux kernel Livepatching, typically for a period of 5 years from LTS release. This FAQ entry contains more information. For Ubuntu 18.04 LTS, where technically feasible, Canonical will provide extended security maintenance to most of the binary packages that reside in the Ubuntu Main Repository for the 64-bit x86 AMD/Intel (amd64), 64-bit ARM (arm64), IBM POWER (ppc64el) and IBM Z and LinuxONE (s390x) architectures. See expanded Security Maintenance for Ubuntu and open source and the service description for additional details. A set of packages is receiving updates only through the snap store as listed below.
