I'm trying to install guix 14.0 on Trisquel 7 and everything went smoothly until I hit the part where you perform some procedures for glibc-locales in the manual.

ruki@ruki-ThinkPad-T400:~$ guix
guile: warning: failed to install locale
warning: failed to install locale: Invalid argument
guix: missing command name
Try `guix --help' for more information.
ruki@ruki-ThinkPad-T400:~$ guix package -i
guile: warning: failed to install locale
warning: failed to install locale: Invalid argument
ruki@ruki-ThinkPad-T400:~$ clear ; guix ; guix package -i glibc-locales
guile: warning: failed to install locale
warning: failed to install locale: Invalid argument
guix: missing command name
Try `guix --help' for more information.

The following package will be upgraded:
   glibc-locales    2.26.105-g0890d5379c -> 2.26.105-g0890d5379c    /gnu/store/j73ld7v624ix39imy94bncxzl8nirdn8-glibc-locales-2.26.105-g0890d5379c

nothing to be done
ruki@ruki-ThinkPad-T400:~$ export GUIX_LOCPATH=$HOME/.guix-profile/lib/locale
ruki@ruki-ThinkPad-T400:~$ guix
guile: warning: failed to install locale
warning: failed to install locale: Invalid argument
guix: missing command name
Try `guix --help' for more information.
ruki@ruki-ThinkPad-T400:~$

I'm not sure what the problem could be right now. Any help is appreciated.
