There is a wee typo in the systemd file *guix-daemon.service* installed on Ubuntu 20.04 by the guix-install.sh script. The text of */root/.config/guix/current/lib/systemd/system/guix-daemon.service *contains the text:
Environment='GUIX_LOCPATH=/var/guix/profiles/per-user/root/guix-profile/lib/locale' LC_ALL=en_US.utf8 The portion .../guix-profile/... should read .../*.guix-profile/*..., in other words the path as given omits the requisite single period (.) as the prefix of the directory .guix-profile. This minor oversight accounts in part for the *guile: warning: failed to install locale *error and related warnings that have cropped up repeatedly when the build daemons are invoked To test this fix: - I edited the guix-daemon.service specification in place at /etc/systemd/system by hand - Rebooted to restart the guix build daemons (I detest systemd and I'm lazy besides) - *guix pull *for my personal userland account - *guix package -u* to upgrade same - *guix package -i libc-utf8-locales* to upgrade my locales from 2.29 to 2.31 - *sudo -i guix pull* to update the root's view of guix - *sudo -i guix package -u* for an upgrade of same - *sudo -i guix package -i glibc-utf8-locales* to have the latest version of the UTF-8 locales installed in ~root/.guix-profile/lib/locale In subsequent user-level *guix install X* commands the warning no longer appears nor do the build daemons complain about failing to set the locale to *en_US.utf8*
