Problem when starting a nix-shell in the plututs repo
# Problem when starting a nix-shell in the plututs repo

(Asked by: username_0 on 2021-05-05)

I was doing the plutus pioneer program and ran into an error when starting a `nix-shell` at the top-level directory of the plutus-repository.

I ran into the same error on `Ubuntu 20.04.2 LTS (GNU/Linux 4.4.0-19041-Microsoft x86_64)`  and `NixOS (20.09.4029.4a154d47623 (Nightingale) on VirtualBox)`.

I also did set up the IOHK binary caches on both systems.

I got the following error when running `nix-shell`:

```
error: build of '/nix/store/z6w41a6dv151g2q95v91yywid7s8mkn5-Agda-plan-to-nix-pkgs.drv' failed
(use '--show-trace' to show detailed location information)

```

The `nix-shell --show-trace` command shows the following error:

```

This question is indeed a dupplicate of [Hash MisMatch Error on Plutus and Nix](https://cardano.stackexchange.com/questions/367/hash-mismatch-error-on-plutus-and-nix)

If you look more closer at the entire error log, there is a mismatch in the sha256 singature of the derivation of ghc:
`hash mismatch in fixed-output derivation '/nix/store/7y3jr1jvzkj2146h7sivw0sfr2bhap3j-ghc-8.4.4-x86_64-deb8-linux.tar.xz`

Same answer, same workaround: the problem disappears when using the IOHK bianry cache for nix.
And there's is indeed an "IMPORTANT" mention at the begining of plutus REAME file asking to do this.

---

On NixOs:

```
# configuration.nix
{ config, pkgs, ... }:
{
  # ... all the rest of the configuration of the server

  # iohk binary caches
  nix = 
  {
    binaryCaches          = [ "https://hydra.iohk.io" "https://iohk.cachix.org" ];
    binaryCachePublicKeys = [ "hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ=" "iohk.cachix.org-1:DpRUyj7h7V830dp/i6Nti+NEO2/nhblbov/8MW7Rqoo=" ];
  };
}

```

---

Ubuntu and other Linuxes

Nix has a configuration in `/etc/nix/nix.conf`. So as to use the IOHK binary cache you have to modify this file:

In the documentation it is said

```
sudo mkdir -p /etc/nix
cat <<EOF | sudo tee /etc/nix/nix.conf
substituters = https://cache.nixos.org https://hydra.iohk.io
