## 2. Nix installation
On the machine you are deploying from:
You can also build Nix from source by following the instructions at https://nixos.org/nix/manual/#ch-installing-source.
Follow the instructions from [Nix installation on debian](#2-nix-installation) (on the machine you are going to deploy from).
1. Install Dependencies (Debian 9 stretch)
```
sudo apt-get install curl git gnupg2 dirmngr
```
2. Install Latest Nix with GPG Verification
```
curl -o install-nix https://nixos.org/nix/install
curl -o install-nix.sig https://nixos.org/nix/install.sig
gpg2 --recv-keys B541D55301270E0BCF15CA5D8170B4726D7198DE
gpg2 --verify ./install-nix.sig
sh ./install-nix --daemon
. /home/user/.nix-profile/etc/profile.d/nix.sh
```
Then follow the instructions. Open a new terminal window when you're done.
If you get an error similar to
```
error: cloning builder process: Operation not permitted
error: unable to start build process
/tmp/nix-binary-tarball-unpack.hqawN4uSPr/unpack/nix-2.2.1-x86_64-linux/install: unable to install Nix into your default profile
```
you're likely not installing as multi-user because you forgot to pass the `--daemon` flag to the install script.
3. Optional: Disallow substitutes
You can put `substitute = false` to your `nix.conf` usually found in `/etc/nix/` to build the packages from source.
This eliminates an attack vector where nix's build server or binary cache is compromised.
