Ubuntu 26.04 is not a released version of Ubuntu (LTS releases occur in April of even years, making 26.04 scheduled for April 2026). Attempting to pull mirror.gcr.io/library/ubuntu:26.04 will fail because the tag does not exist. Please revert this change to keep using a stable, existing LTS release like 24.04.
