The workaround for you in the meantime is to run: guix build nss-certs --no-substitutes before you run ‘sudo guix system reconfigure’. The client ‘guix system’ in this case was running in the “C” locale because “en_AU.utf8” is not among the locales in ‘glibc-utf8-locales’, which is what’s bundled with ‘guix’. Thus, ‘set-build-options’ in (guix store) would send “C” as the “locale” property. Then, ‘guix substitute’ would do (setlocale LC_ALL "C"), from this code: ;; Attempt to install the client's locale, mostly so that messages are ;; suitably translated. (match (or (find-daemon-option "untrusted-locale") (find-daemon-option "locale")) (#f #f) (locale (false-if-exception (setlocale LC_ALL locale)))) Consequently, it would run in a ASCII locale and would thus fail to decode non-ASCII file names that appear in nss-certs. Similar problems could occur anytime someone runs a client in a non-UTF-8 locale. One way to reproduce it for me is this (I use ‘time-machine’ to get a version of ‘nss-certs’ not already available on my disk): --8<---------------cut here---------------start------------->8--- $ LC_ALL=C guix time-machine --commit=8aeef3c7bdf278003892e608842200d3a35211c7 -- build nss-certs Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'... 0.1 MB will be downloaded: /gnu/store/igklwlj1j60kdgrhcn6m2p2iqp87qrrs-nss-certs-3.52 substituting /gnu/store/igklwlj1j60kdgrhcn6m2p2iqp87qrrs-nss-certs-3.52... downloading from https://ci.guix.gnu.org/nar/lzip/igklwlj1j60kdgrhcn6m2p2iqp87qrrs-nss-certs-3.52 ... nss-certs-3.52 133KiB 1.9MiB/s 00:00 [######## ] 48.3%Backtrace: In ice-9/boot-9.scm: 1736:10 4 (with-exception-handler _ _ #:unwind? _ # _) In unknown file: 3 (apply-smob/0 #) In ice-9/boot-9.scm: 718:2 2 (call-with-prompt _ _ #) In ice-9/eval.scm: 619:8 1 (_ #(#(#))) In guix/ui.scm: 2046:12 0 (run-guix-command _ . _) guix/ui.scm:2046:12: In procedure run-guix-command: Throw to key `encoding-error' with args `("scm_to_stringn" "cannot convert wide string to output locale" 84 #f #f)'. substitution of /gnu/store/igklwlj1j60kdgrhcn6m2p2iqp87qrrs-nss-certs-3.52 failed guix build: error: some substitutes for the outputs of derivation `/gnu/store/mzrh9ad4sqqg88ym9c1x1vv2lqjyxbrv-nss-certs-3.52.drv' failed (usually happens due to networking issues); try `--fallback' to build derivation from source --8<---------------cut here---------------end--------------->8--- This is fixed by commit 739f6309478d8ab8501bb653ceb2f634c8560f55, with two additional improvements: fe4e770fc1 ui: Attempt to fall back to "en_US.utf8" rather than "C". 739f630947 store: 'set-build-options' sends LC_MESSAGES, not LC_ALL. aba8def46d substitute: Set LC_MESSAGES to the client's locale, not LC_ALL.
