[Message part 3 (text/plain, inline)]

Hi,

I just installed guix on top of Debian Buster using the installation script
at guix.gnu.org. I did this on two machines, hat and wand, with the hope
that I could offload compilation to wand.

This is what I get:

root <at> hat:~# guix offload test
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.

guix offload: testing 1 build machines defined in

Any hints about what could be wrong?

Best regards,
Mikael Djurfeldt
