This is a bug in guix pull. It has already been reported and we're 
working
on a fix. That shouldn't cause any issue on your side: the failure to 
pull
simply means that your guix wasn't updated. As a workaround, you can try 
again
as long as it fails in this way. "guix pull --cores=1" might help too.

The error is not in the package definitions, it's more likely a race 
condition
introduced with the recent guix pull update.

Sorry about the bad experience :/ As I said, all this is due to the fact 
that
guix evolves really fast. That's also the reason why we still consider 
it
beta. Had you tested it a few days earlier, everything would have been
going smoothly.

Thank you for your advice :) I think you're right: we are still beta, so
errors are to be expected from time to time. We should fix them before 
we
go 1.0. That said, the system is robust enough that you can always 
recover
from said errors.
