Hey I pushed to core-updates, but the evaluation on ci.guix.gnu.org seems to have failed. Nothing stands out to me in the log [1], but the Guix Data Service also failed to load this revision [2], and the failure there was building Python [3]. 1: http://ci.guix.gnu.org/eval/10060/log/raw 2: http://data.guix.gnu.org/revision/227fab3ed8842b22337196ee21c79143fc093855 3: http://data.guix.gnu.org/job/10692#bottom I tried building that same derivation again, and I got the same failure. Thanks, Chris
