Put this in a vim buffer and in command mode run :w !bash to execute buffer contents via bash:
If you get something along
/nix/store/61mibb0k5mxnsxzb4x2737cbysn4c5ha-home-manager/bin/home-manager: line 71: NIX_PATH: unbound variable
check if you have run this already:
. ~/.nix-profile/etc/profile.d/nix.sh
In the home.nix this translates to:

Troubleshooting

I tried setting (IDK if/how that impacts the build)
nix.useSandbox = false;
nix.trustedBinaryCaches = [ "https://hydra.nixos.org/" ];
in ~/config/nixpkgs/config.nix and then restarted the build with (latest "green" commit on master, https://status.nixos.org/):

Retrying with nix reinstall
Remove /nix first then use https://releases.nixos.org/nix/nix-2.3.8/install (via https://releases.nixos.org/)
Use as nix.conf:
sandbox = false
trusted-substituters = https://hydra.nixos.org/
allowed-users = me root
use-sqlite-wal = false
If errors:
NIX_PATH=nixpkgs=https://github.com/NixOS/nixpkgs/archive/85abeab48b5feda4b163e5bb32f50aad1164e415.tar.gz nix-shell -p nix-info --run "nix-info -m"
Failing same (autogen) error.

Retrying (https://nix.dev/reference/pinning-nixpkgs.html):
NIX_PATH=nixpkgs=http://nixos.org/channels/nixos-20.09/nixexprs.tar.xz:home-manager=https://github.com/nix-community/home-manager/archive/release-20.09.tar.gz ...
Took the hint from NixOS/nixpkgs#106165 to deactivate my overlays first, then reinstalled, succeeded. So first:
cd ~/.config/nixpkgs/overlays
for name in *\.nix; do newname=${name%\.nix}.preinstall-deactivated-nix; mv $name $newname; done
And then (using pinning approach, https://nix.dev/reference/pinning-nixpkgs.html):
NIX_PATH=nixpkgs=http://nixos.org/channels/nixos-20.09/nixexprs.tar.xz:home-manager=https://github.com/nix-community/home-manager/archive/release-20.09.tar.gz nix-shell --show-trace -E 'with import {}; mkShell { buildInputs = [ (callPackage ~/.config/nixpkgs/home-sources.nix {}).home-manager ]; }' --run "home-manager -b backup -f ~/.config/nixpkgs/home.nix switch"
succeeds ! (TODO Find offending overlay or add the one mentioned in NixOS/nixpkgs#106165)
Right now testing:
NIX_PATH=nixpkgs=https://channels.nixos.org/nixpkgs-unstable/nixexprs.tar.xz:home-manager=https://github.com/nix-community/home-manager/archive/master.tar.gz nix-shell --show-trace -E 'with import {}; mkShell { buildInputs = [ (callPackage ~/.config/nixpkgs/home-sources.nix {}).home-manager ]; }' --run "home-manager -b backup -f ~/.config/nixpkgs/home.nix switch"
