Does Ubuntu 24.04 support hibernation?

Though the Generative AI response has a lot of back-and-forth answer.

As of now, Amazon EC2 does not support hibernation for Ubuntu 24.04. For the most recent information, please refer to the updated documentation: AWS EC2 Hibernation Prerequisites. Amazon communicates updates through documentation changes, "What's New" announcements, or blog posts.

See the list of "What's New" Hibernation announcements for your reference: AWS 'What's New'—Hibernation Announcements.

Based on the available information, Ubuntu 24.04 is not currently listed as officially supported for EC2 instance hibernation. The most recent Ubuntu version mentioned in the documentation for hibernation support is Ubuntu 22.04.2 LTS (Jammy Jellyfish).

It's important to note that Ubuntu 24.04 has not been released yet, as it is scheduled for release in April 2024. AWS typically adds support for new Ubuntu LTS versions after they are officially released and have undergone testing to ensure compatibility with EC2 hibernation.

While it's possible that Ubuntu 24.04 might work with hibernation once it's released, it would not be advisable to assume compatibility or rely on it for production use until AWS officially announces support. AWS regularly updates their supported AMIs for hibernation, so it's likely that Ubuntu 24.04 will be added to the list of supported versions after its release and necessary testing.

For the most up-to-date and reliable information on supported AMIs for EC2 hibernation, it's best to refer to the official AWS documentation or contact AWS support directly. If you need to use hibernation with Ubuntu, it's recommended to stick with the currently supported versions like Ubuntu 22.04.2 LTS until official support for Ubuntu 24.04 is announced.
