Ubuntu 26.04 is not yet a released LTS version (scheduled for April 2026). Attempting to use ubuntu:26.04 will fail because the tag does not exist on mirror.gcr.io or Docker Hub. Additionally, many of the third-party repositories and packages installed later in this Dockerfile (such as Docker CE, Microsoft ODBC, and Chrome) do not yet have support or packages built for Ubuntu 26.04. Please keep the base image at ubuntu:24.04 until 26.04 is officially released and supported.
