apt-get update fails - Failed to fetch jessie backports repository

[rocketlobster]

Since the jessie-updates repository has been removed, every attempt to run apt-get update fails with the following stacktrace:

W: Failed to fetch http://httpredir.debian.org/debian/dists/jessie-updates/main/binary-amd64/Packages  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.
The command '/bin/sh -c apt-get update -qq && apt-get install liblcms2-utils' returned a non-zero code: 100
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/docker" failed: exit status 100

Maybe Google should just re-build and publish one image to fix it for everyone?

How are you reproducing this error? The current image is based on Ubuntu, not Debian, and should not be using Jessie-related repositories at all.
