Canonical Announces Major Ubuntu Kernel Change

A New Approach to Kernel Version Selection

Introducing a More Predictable and Stable Kernel Upgrade Process

Canonical, the company behind Ubuntu, has announced a major change to the way it selects kernel versions for its popular Linux distribution. The new approach, detailed in a blog post by Ubuntu Server Technical Lead Will Cooke, is designed to make the kernel upgrade process more predictable and stable.

Under the old approach, Canonical would typically select the latest stable kernel version for each point release of Ubuntu. However, this could sometimes lead to problems, as new kernels can introduce bugs or other issues. The new approach will address this problem by introducing a new concept called "Long-Term Support" (LTS) kernels.

LTS kernels will be supported for a longer period of time than regular kernels, and they will only receive security and stability updates. This will make it easier for users to stay on a stable kernel version without having to worry about potential problems caused by new features or changes.

The first LTS kernel for Ubuntu will be Linux 5.15, which will be used in Ubuntu 22.04 LTS. Canonical plans to release new LTS kernels every two years, and they will be supported for five years after their release.

In addition to LTS kernels, Canonical will also continue to offer regular kernels for users who want to stay on the latest version. However, the LTS kernels are expected to be the default choice for most users, as they provide a more stable and predictable upgrade process.

The new approach to kernel version selection is a significant change for Ubuntu, but it is one that is likely to benefit users in the long run. By providing LTS kernels, Canonical is making it easier for users to stay on a stable and secure kernel version, while still having the option to upgrade to the latest version if they want to.
