Thanks, Frank, I've sponsored your upload of s390x-tools. I added this
bug in d/ch entry though:

$ dput ubuntu ../s390-tools_2.33.1-0ubuntu4_source.changes

Bug description:
  This issue has already been identified and fixed in the (upstream?)
  github repository:
  https://github.com/ibm-s390-linux/s390-tools/commit/63ff07ba38dda99e2661a097d05266555c727a2e

  The issue fixed by the revert linked above is causing Cloudware
  Oracular download image builds to fail on s390x. From the image build
  log:

  ```

  The fix is in the github repo but not yet released. The LP builders
  for Oracular are using version 2.33.1, which contains the bug.
