This bug is resolved by following the current documentation and executing export NIX_REMOTE=daemon .
However, even then the import fails: $ guix import nix nixpkgs/ hello ;;; SSAX warning: Skipping PI: xml trace: warning: `stdenv.isArm` is deprecated after 18.03. Please use `stdenv.isAarch32` instead trace: lib.zip is deprecated, use lib.zipAttrsWith instead trace: Warning: `showVal` is deprecated and will be removed in the next release, please use `traceSeqN` trace: `mkStrict' is obsolete; use `mkOverride 0' instead. trace: `lib.nixpkgsVersion` is deprecated, use `lib.version` instead! And after about 15 minutes the import crashes with a stack overflow. Andreas
