Hi Pjotr, Thank you.

Having successfully upgraded my root and user Guix installations I now find that my development installation is unable to locate guile-gcrypt: $ ./pre-inst-env guix --version ERROR: In procedure scm-error: no code for module (gcrypt hash) If I use my root guix profile, in a simlar way to your suggestion, it works: $ sudo GUILE_LOAD_PATH=/root/.guix-profile/share/guile/site/2.2 ./pre- inst-env guix --version guix (GNU Guix) 0.15.0.1558-b0632 Is there a best way to notify the ./pre-inst-env commands about guile- gcrypt? Using sudo seems like the wrong approach. Would installing guile-gcrypt as the development user suffice? Best regards, Paul.
