The Ubuntu version 26.04 is not a released version of the operating system and does not exist in the registry. Ubuntu LTS releases follow a biennial cycle, and the next LTS (26.04) is not expected until 2026. This change will cause the Docker build to fail with a 'manifest not found' error. It appears the automated dependency update incorrectly identified the next major LTS version before its release. Additionally, any future base image upgrade should also address version-specific configurations elsewhere in the file, such as the Microsoft SQL Server repository on line 103 (currently pinned to 20.04) and the deprecated apt-key usage.
