I am getting this error right now on multiple machines: substitute: updating list of substitutes from 'http://mirror.hydra.gnu.org'... 100.0% substitute: updating list of substitutes from 'http://mirror.hydra.gnu.org'... 100.0% substitute: updating list of substitutes from 'http://mirror.hydra.gnu.org'... 66.7%Backtrace: substitute: In ice-9/boot-9.scm: substitute: 160: 9 [catch #t #<catch-closure 1d5ba00> ...] substitute: In unknown file: substitute: ?: 8 [apply-smob/1 #<catch-closure 1d5ba00>] substitute: In ice-9/boot-9.scm: substitute: 66: 7 [call-with-prompt prompt0 ...] substitute: In ice-9/eval.scm: substitute: 432: 6 [eval # #] substitute: In ice-9/boot-9.scm: substitute: 2412: 5 [save-module-excursion #<procedure 1d7c900 at ice-9/boot-9.scm:4084:3 ()>] substitute: 4089: 4 [#<procedure 1d7c900 at ice-9/boot-9.scm:4084:3 ()>] substitute: 1734: 3 [%start-stack load-stack ...] substitute: 1739: 2 [#<procedure 1d8eb40 ()>] substitute: In unknown file: substitute: ?: 1 [primitive-load "/gnu/store/nqy9m6hhnkkfwr5wyq5bac96v9s9hc9i-guix-0.12.0-9.25a4/bin/.guix-real"] substitute: In guix/ui.scm: substitute: 1255: 0 [run-guix-command substitute "--query"] substitute: substitute: guix/ui.scm:1255:8: In procedure run-guix-command: substitute: guix/ui.scm:1255:8: Throw to key `bad-response' with args `("Bad Response-Line: ~s" (""))'. guix environment: error: build failed: substituter `substitute' died unexpectedly Some deprecated features have been used. Set the environment variable GUILE_WARN_DEPRECATED to "detailed" and rerun the program to get more information. Set it to "no" to suppress this message.
It doesn't seem to be caused by either the guix system revision or the userspace guix version I'm running. This happens with any operations that use substitutes right now. Are other people experiencing this? What happened, and what's causing it... do we know?
