Grub : Could not delete variable: Invalid argument

[Akram Chehaima]

Hey
My system was  working fine , like other days
I run these routine commands

# guix pull

But whene i run

# sudo guix system reconfigure  /etc/config.scm

I have problem message from grub:


slack@planet ~$ sudo guix system reconfigure  /etc/config.scm 
guile: warning: failed to install locale
hint: Consider installing the `glibc-utf8-locales' or `glibc-locales' package 
and defining `GUIX_LOCPATH', along these lines:

     guix package -i glibc-utf8-locales
     export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"

See the "Application Setup" section in the manual, for more info.

Note that I have not restarted the system yet.
Is there a solution ?
