Hi! I found a workaround, starting the guix-daemon manually with PATH and --disable-chroot:
stefan@guix ~$ sudo herd stop guix-daemon Service guix-daemon has been stopped. stefan@guix ~$ sudo PATH=/gnu/store/x3gq648qnfnla7nppyfjvj62s2i8y7rl-guile-3.0.2/bin /gnu/store/ca91bk34z3hmzv5d8j5xi0z8f4riyx7m-guix-1.2.0-8.7624ebb/bin/guix-daemon --build-users-group guixbuild --max-silent-time 0 --timeout 0 --log-compression bzip2 --discover=no --substitute-urls https://ci.guix.gnu.org --disable-chroot & Now ‘guix build --system=aarch64-linux guix’ is running, however, it is not finished yet. Bye Stefan
