The travis log usually ends with this:
Rebuilding docker image ubuntu-bionic Sending build context to Docker daemon 11.78kB Step 1/48 : FROM buildpack-deps:bionic-scm bionic-scm: Pulling from library/buildpack-deps : Pulling from library/buildpack-deps toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit The command "if [[ `uname` == "Linux" ]]; then build/docker/refresh.sh; fi" failed and exited with 1 during . Your build has been stopped. Not sure if there's a good solution to that. Does the ASF have a contract with docker, or maybe have an internal docker registry mirror, or something? Or maybe since the ASF has a contract with travis, we should escalate this to travis?
