Pulp

Run this code:

#!/bin/bash

set -ev

repo_name="repo$RANDOM"
remote_name="remote$RANDOM"
url="https://fixtures.pulpproject.org/file-invalid/PULP_MANIFEST"

pulp file remote create --name $remote_name --url $url
pulp file repository create --name $repo_name --remote $remote_name
pulp file repository sync --name $repo_name

It'll error and you'll get a stack trace (pulpcore.exceptions.validation.DigestValidationError: A file failed validation due to checksum.). However, it doesn't tell you much information like what the problematic file is.
