Ubuntu 26.04 is not a released stable LTS version. Upgrading the base image to an unreleased version will cause the Docker build to fail, as many package repositories (such as Microsoft ODBC, Bazel, and Google Chrome) do not yet support Ubuntu 26.04. Please keep the base image at ubuntu:24.04 until 26.04 is officially released and supported by all required dependencies.
