While the manual documents how to compare a failing challenge result $ wget -q -O - https://ci.guix.info/nar/=E2=80=A6-git-2.5.0 \ | guix archive -x /tmp/git $ diff -ur --no-dereference /gnu/store/=E2=80=A6-git.2.5.0 /tmp/git To check "git", you need to run "guix challenge git" and if the results are inconclusive, manually cut-and-paste the correct URL(s) from the challenge output and manually download it and unpack with guix archive, and then run a comparison utility... What about an argument to "guix challenge" that handles the downloading and unpacking to a temporary directory, and possibly another that also runs a comparison tool against the results. Maybe something like: $ guix challenge --download-differences /tmp/git-XXXXX/SUBSTITTE-X/...-git-2.5.0 /tmp/git-XXXXX/SUBSTITUTE-Y/...-git-2.5.0 /gnu/store/...-git-2.5.0 Downloads and unpacks the substitutes, and outputs the resulting directories. $ guix challenge --download-differences --compare-with=3D"diffoscope ..." This would do the above, plus run diffoscope on the directories ... though I think diffoscope can only compare between two things at a time... so that might get difficult if many substitutes return results. live well, vagrant --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQRlgHNhO/zFx+LkXUXcUY/If5cWqgUCXNHIHQAKCRDcUY/If5cW qmXdAP95qyDG+bnknxZfhFVFZuzE3eLIhLSbvAm76MmQPpHCQgD/UGZudd1dDL2D hmIIUuXK1VkwbLge+7R2pzOZaJ2uDgs= =/t7l -----END PGP SIGNATURE----- --=-=-=--
