Alternatively you can build NixOS from source by following the instructions at https://nixos.org/nixos/manual/index.html#sec-building-cd.
2. Write NixOS iso to install media (USB/CD). For example:
```
cp nixos-minimal-23.05.3701.e9b4b56e5a20-x86_64-linux.iso /dev/sdX
cp nixos-minimal-25.11.1056.d9bc5c7dceb3-x86_64-linux.iso /dev/sdX
```
Replace /dev/sdX with the correct device name. You can find this using `sudo fdisk -l`

The following steps are meant to be run on the machine you deploy from, not the machine you deploy to.
You can also build Nix from source by following the instructions at https://nixos.org/nix/manual/#ch-installing-source.
1. Install Dependencies (Debian 10 Buster)
1. Install Dependencies (Debian/Ubuntu)
```
sudo apt-get install curl git gnupg2 dirmngr
sudo apt-get install curl git xz-utils
```
2. Install latest Nix in "multi-user mode" with GPG Verification according to https://nixos.org/nix/download.html

```
curl -o install-nix-2.3.10 https://releases.nixos.org/nix/nix-2.3.10/install
curl -o install-nix-2.3.10.asc https://releases.nixos.org/nix/nix-2.3.10/install.asc

gpg2 --verify ./install-nix-2.3.10.asc
sh ./install-nix-2.3.10 --daemon
curl -L https://nixos.org/nix/install | sh -s -- --daemon
```
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.
