I do not know what is wrong, but some thing is. From https://lists.gnu.org/archive/html/guix-devel/2020-10/msg00096.html the commit ranges: https://data.guix.gnu.org/repository/1/branch/master/package/ghc-haddock/ou= tput-history does not match with the Git history if I am not wrong. The first commit producing j5llsz=E2=80=A6-ghc-haddock is not 3922208091 but 12dc9f58c4. And then compare: author date commit date 3922208091|Thu Jul 23 14:03:19 2020|Fri Jul 24 14:21:31 2020 12dc9f58c4|Fri Jul 24 09:56:25 2020|Fri Jul 24 14:21:30 2020 I have not checked what guix-commits says. Maybe the mess is overthere. All the best, simon
