Manifest not found

[Robula]

I'm trying to use launcher.gcr.io/google/ubuntu18_04 for a custom build container on GCP Cloud build but I can't build the container due to missing manifest.

Dockerfile:

FROM launcher.gcr.io/google/ubuntu18_04

RUN apt-get update && \
  apt-get -y install zip

ENTRYPOINT ["zip"]

Cloud Build Log
