Download of substituted binaries fails when one is offline. This is logical, but should guix then not gracefully fall back to compilation if the sources have already been downloaded?
In any case, catching the error and emitting an error message would probably be preferable to $ guix build hello The following file will be downloaded: /nix/store/7g06kqdm6qjbzdppnryyvjl2bz82r8dh-hello-2.8 @ substituter-started /nix/store/7g06kqdm6qjbzdppnryyvjl2bz82r8dh-hello-2.8 /usr/local/guix-git/libexec/guix/substitute-binary Backtrace: In ice-9/boot-9.scm: 149: 12 [catch #t #<catch-closure 1c131a0> ...] 157: 11 [#<procedure 1bb10f0 ()>] In unknown file: ?: 10 [catch-closure] In ice-9/boot-9.scm: 63: 9 [call-with-prompt prompt0 ...] In ice-9/eval.scm: 407: 8 [eval # #] In ice-9/boot-9.scm: 2111: 7 [save-module-excursion #<procedure 1bb6100 at ice-9/boot-9.scm:3646:3 ()>] 3651: 6 [#<procedure 1bb6100 at ice-9/boot-9.scm:3646:3 ()>] In unknown file: ?: 5 [load-compiled/vm "/root/.cache/guile/ccache/2.0- LE-8-2.0/usr/local/guix-git/bin/guix.go"] In guix/ui.scm: 460: 4 [run-guix-command substitute-binary "--substitute" ...] In guix/scripts/substitute-binary.scm: 428: 3 [guix-substitute-binary "--substitute" ...] In guix/web.scm: 151: 2 [loop #] In web/client.scm: 45: 1 [open-socket-for-uri #] In unknown file: ?: 0 [getaddrinfo "hydra.gnu.org" "http" ...] ERROR: In procedure getaddrinfo: ERROR: In procedure getaddrinfo: Der Name oder der Dienst ist nicht bekannt @ substituter-failed /nix/store/7g06kqdm6qjbzdppnryyvjl2bz82r8dh-hello-2.8 256 fetching path `/nix/store/7g06kqdm6qjbzdppnryyvjl2bz82r8dh-hello-2.8' failed with exit code 1 guix build: error: build failed: some substitutes for the outputs of derivation `/nix/store/bc6hgclkr7a3yq3xh7h6m7myagfdwvdj-hello-2.8.drv' failed; try `--fallback' In the past, I think I also ran into a similar problem even when using "-- no-substitutes", as guix tried in vain to check for newer versions of gnu packages, but I cannot reproduce this problem now.
