Hi. Important note: The failure happens randomly, not always, so a single successful build should not be interpreted as the problem not being there.
The failure rate I get here is around 80% (tested on machines with 1 CPU and 2 CPUs, without significant differences between them). It's also interesting to see that the same failure (No module named 'delme') happened at least once while running the s390x autopkgtests: https://ci.debian.net/packages/p/python-scitrack/testing/s390x/73953161/ Thanks.
