I’ve got a reproducible build failure when a particular off-the-shelf Docker image is specified for a job in
config.yml. The image,
kcov/kcov:latest, is downloaded successfully in the setup phase, and I can also download it locally without problems. However, the
attach_workspace step fails with an error:
Error downloading workspace layer for job a491b12f-1e3d-41f6-9568-4460eecf7f8d: RequestError: send request failed caused by: Get https://circle-production-customer-artifacts.s3.amazonaws.com/?list-type=2&prefix=picard%2F5a9c03d706e7a707755d9bba%2Fworkflows%2Fworkspaces%2Ff462365f-46d0-40ee-8063-2981ae991a43%2F0%2Fa491b12f-1e3d-41f6-9568-4460eecf7f8d: x509: certificate signed by unknown authority
Replacing the job image with
ragnaroek/kcov:v33 makes the problem go away.
