Hello, I'm not sure if this is a bug or I'm just not using things properly.
I ran 'guix pull' a few minutes ago, followed by: $ cat guix-os.scm (use-modules (gnu bootloader) (gnu bootloader grub) (gnu system file-systems)) (operating-system (host-name "jsynacek-guix-os") (timezone "Europe/Prague") (locale "en_US.utf8") (bootloader (bootloader-configuration (bootloader grub-efi-bootloader) (target "/dev/sdx"))) (file-systems (list (file-system (mount-point "/home") (device "/dev/sda33") (type "ext4"))))) $ guix system build guix-os.scm substitute: /gnu/store/29jhbbg1hf557x8j53f9sxd9imlmf02a-bash-minimal-5.0.7/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.utf8) substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% 50.0 MB will be downloaded: /gnu/store/g56i8savnfr7981fil03idkjl0syj29d-linux-libre-5.4.31 substituting /gnu/store/g56i8savnfr7981fil03idkjl0syj29d-linux-libre-5.4.31... /gnu/store/29jhbbg1hf557x8j53f9sxd9imlmf02a-bash-minimal-5.0.7/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.utf8) downloading from https://ci.guix.gnu.org/nar/lzip/g56i8savnfr7981fil03idkjl0syj29d-linux-libre-5.4.31... linux-libre-5.4.31 48.6MiB 2.3MiB/s 00:22 [##################] 100.0% Backtrace: In ice-9/boot-9.scm: 1736:10 4 (with-exception-handler _ _ #:unwind? _ #:unwind-for-type _) In unknown file: 3 (apply-smob/0 #<thunk 7fe0bbf9e3a0>) In ice-9/boot-9.scm: 718:2 2 (call-with-prompt _ _ #<procedure default-prompt-handler (k proc)>) In ice-9/eval.scm: 619:8 1 (_ #(#(#<directory (guile-user) 7fe0bbc16f00>))) In guix/ui.scm: 1936:12 0 (run-guix-command _ . _) guix/ui.scm:1936:12: In procedure run-guix-command: In procedure struct-vtable: Wrong type argument in position 1 (expecting struct): #f Regards, -- Jan Synacek Software Engineer, Red Hat
