Hi everyone, Jumping in with a possibly related problem reported by a participant of the Reproducible Research MOOC.
He gets an error when running an example from one of our exercises: guix time-machine --channels=channels.scm -- shell --container --network --manifest=manifest.scm -- jupyter lab guix-science/build-system/node.scm:119:2: error: #{ %make-build-system-procedure/abi-check}#: unbound variable hint: Did you forget a `use-modules' form? It's this error message that led me to this thread. He gets the same error message when running some of our other examples. I asked for his channels and did a "guix pull" on my machine with the exact same ones. But there's no problem for me, everything works fine. Inspired by the reference to "old guix-daemon", I asked him to update his daemon. After that, he still gets the error message but the time-machined "shell" command is run nevertheless - and produces another error that it doesn't produce on my machine. Are there any diagnostics we can do to explore this issue? Cheers, Konrad
