Updating AL2023

Focus mode
Updating AL2023 - Amazon Linux 2023

It's important to keep up to date with AL2023 releases so that you can benefit from security updates and new features. With AL2023, you can ensure consistency between package versions and updates across your environment through Deterministic upgrades through versioned repositories on AL2023.

Warning

Running dnf --releasever=latest update is not best practice, and is likely to result in an OS update being first tested in production.

Instead of using latest, use a specific AL2023 release version. This ensures you are deploying the same changes across production instances as you previously tested. For example, dnf --releasever=2023.7.20250331 update will always update to the 2023.7.20250331 release.

For more information, see the Updating AL2023 section in the AL2023 User Guide.
