That's strange that there isn't a log file to report, it looks like util-linux didn't build but I'm not sure. What you could try is to run `guix pull -v3' to enable more verbosity, and it should show build output for packages as it's building them. > I don't fully understand what guix pull does. If I was to run it again, would everything begin from the start, or is there some chance re-running it would pick up where it left off? Yeah, luckily guix pull should pickup where it left off and not rebuild packages that are already built and present in /gnu/store. So normally, you should only have to go through the couple of days of building once (Well actually, in normal times we should have binary substitutes that guix pull can download instead of building them, but the CI is having issues with aarch64 at the moment :-/.). That being said, new commits could be pushed and cause new rebuilds between guix pull invokation, what you can do is pull a specific commit first: guix pull -v3 --commit=2641621 # Commit picked from the log file. Hope that helps! Thanks, Pierre
