Hi Guixers,

I installed Guix System on another laptop and made a mistake in my 
config.scm file
but I don't know where.

Could somebody have a look?


Error unbound variable in cups...

this is my config.scm file:

;; by the graphical installer.

franz@akoya ~$  sudo guix system reconfigure /etc/config.scm
hint: Consider installing the `glibc-locales' package and defining 
`GUIX_LOCPATH', along these lines:

      guix install glibc-locales
      export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"

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

2. question:

hint: Consider installing the `glibc-locales' package and defining 
`GUIX_LOCPATH', along these lines:

      guix install glibc-locales
      export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"
------------------------------------------------------------
I did this twice, but this message comes again.
What can I do?

Kind regards
