Hi Richard, I've encountered the diffoscope failure as well, and looked at their repo to see how new version 271 was and what activity has happened since. It looks like they may have already fixed the test failures, pending a new release: https://salsa.debian.org/reproducible-builds/diffoscope/-/commit/0743d63f85f298131e78045ec6d73acdc50b97eb
Cheers, Kaelyn
