For the narinfo of 'hello' from ci.guix.gnu.org, I see there is also a gzipped substitute available, maybe that's the difference? I guess the solution or work-around is to update the guix daemon (I'm guessing it's an old version). If that fails, you could for now avoid the broken(?) substitute of git-minimal by building things locally: $ guix pull --keep-going --fallback # download as much substitutes as we can, even if eventually it fails # sometimes --fallback doesn't work (I don't recall the details), build the remainder locally $ guix pull --no-substitutes Greetings, Maxime. (?) I don't know if this is a bug in the old or new substitution code or in Cuirass.
