Ubuntu 18.04 LTS officially transitions to extended security maintenance phase

News on June 1, Canonical issued a notice today, announcing Ubuntu 18.04 LTS (codename Bionic Beaver) operating system series has officially entered the Extended Security Maintenance (ESM) phase, effective immediately from May 31, 2023.

As far as the editor understands, Ubuntu 18.04 LTS (Bionic Beaver) is a long-term support version of the operating system that has moved into extended security maintenance after five years of standard support maintenance. A similar situation will also happen with Ubuntu 16.04 in April 2024 ESM products.

Ubuntu 18.04 LTS was released on April 26, 2018, and will continue to be supported with critical bug fixes and security updates for five years until April 2028 through the Extended Security Maintenance (ESM) package provided by Canonical.

In order for businesses that rely on stability and cannot upgrade to newer Ubuntu LTS versions to benefit from the five years of support provided by Bionic Beaver, they are recommended to purchase Ubuntu Pro subscription.

Ubuntu Pro subscription is available on multiple architectures, including amd64, arm64, s390X and PowerPC, and is available on desktops, servers, IoT devices, Amazon Web Services (AWS), Azure, Google Public cloud platforms such as Cloud, as well as platforms such as IBM Cloud and Oracle Cloud.

Canonical says: “By subscribing to Ubuntu Pro, you can ensure Ubuntu 18.04 LTS is fully supported until 2028. This extended support period provides ongoing assistance and maintenance for your workloads. ”

For those users who have no plans to purchase an Ubuntu Pro subscription, we strongly recommend that they upgrade their installation to Ubuntu 22.04 LTS (codename Jammy) as soon as possible Jellyfish). This version brings an updated kernel, supports more devices, and contains many update packages.

Canonical points out that the upgrade path from Ubuntu 18.04 LTS is through Ubuntu 20.04 LTS and then upgrading to Ubuntu 22.04 LTS.

Users still running Ubuntu 18.04 after May 31, 2023 will not receive any security updates, putting their systems at risk of security threats.
