Image build failures with logs similar to the following lead to frequent pipeline failures. I've only observed this failure on bullseye, so it seems to occur more frequently there, if not necessarily exclusively. Specific example of a failed job is [9522858](https://salsa.debian.org/cloud-admin-team/debian-cloud-images-daily/-/jobs/9522858) It's not clear from the logs what the actual failure was. Capturing `debootstrap.log` may be a worthwhile next step. ``` I: Extracting util-linux... I: Extracting zlib1g...
