Hello,
I just ran “guix pull && guix package -u” and after downloading many substitutes, guix package aborted with the following error: --8<---------------cut here---------------start------------->8--- ⋮ substitute: atualizando substitutos de "https://ci.guix.gnu.org"... 0.0%Backtrace: substitute: 14 (primitive-load "/gnu/store/yxh9kr0150494jf8phrf1x28mhw…") substitute: In guix/ui.scm: substitute: 2230:7 13 (run-guix . _) substitute: 2193:10 12 (run-guix-command _ . _) substitute: In ice-9/boot-9.scm: substitute: 1752:10 11 (with-exception-handler _ _ #:unwind? _ # _) substitute: 1752:10 10 (with-exception-handler _ _ #:unwind? _ # _) substitute: In guix/scripts/substitute.scm: substitute: 757:18 9 (_) substitute: 348:26 8 (process-query #<output: file 4> _ #:cache-urls _ #:acl _) substitute: In guix/substitutes.scm: substitute: 365:27 7 (lookup-narinfos/diverse _ _ #<procedure 7f22cf4534a0 …> …) substitute: 322:31 6 (lookup-narinfos "https://ci.guix.gnu.org" _ # _ # _) substitute: 245:26 5 (fetch-narinfos _ _ #:open-connection _ # _) substitute: In ice-9/boot-9.scm: substitute: 1685:16 4 (raise-exception _ #:continuable? _) substitute: 1685:16 3 (raise-exception _ #:continuable? _) substitute: 1780:13 2 (_ #<&compound-exception components: (#<&error> #<&orig…>) substitute: 1685:16 1 (raise-exception _ #:continuable? _) substitute: 1685:16 0 (raise-exception _ #:continuable? _) substitute: substitute: ice-9/boot-9.scm:1685:16: In procedure raise-exception: substitute: In procedure write_wait_fd: unimplemented guix package: erro: `/gnu/store/yxh9kr0150494jf8phrf1x28mhwnnv7f-guix-command substitute' died unexpectedly popigai: (1) guix describe Geração 144 15 jun 2022 22:55:58 (atual) guix 128697d URL do repositório: https://git.savannah.gnu.org/git/guix.git ramo: master commit: 128697d43c21eb229ff5413f1c4cf79ae1a9dcd4 --8<---------------cut here---------------end--------------->8--- I immediately ran “guix package -u” again, and this time the command completed successfully. I had a quick look at ‘fetch-narinfos’ but I couldn't figure out what could be calling into this unimplemented function ‘write_wait_fd’… -- Thanks Thiago
