ok so you fucked up, what next,

Step 1

Either create a new VM or if still have access, go to ISOs and put in nixos 22.05 iso and reboot server. If create new vm, please change DNS and update IPs in the main nix config and this document (v6) and set rhost

Step 2

Use console to set ssh password.

SSH in ssh root@hetzner-vm.servers.genderfucked.monster

Add ssh key echo "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIAeN3T1aZkTm5xS0b66cRDyKUbdEQCFyzVWXeW+eIbsa chaos@chaos" >> /root/.ssh/authorized_keys

Step 3

Install NixOS.

parted -s "/dev/sda" -- mklabel msdos
parted -s "/dev/sda" -- mkpart primary 512MiB 100%
parted -s "/dev/sda" -- print

mkfs.ext4 /dev/sda1

mount /dev/sda1 /mnt

nixos-generate-config --root /mnt

Edit configuration.nix and replace with

{ config, pkgs, ... }:
{
  imports = [ ./hardware-configuration.nix ];
  users.users.root = {
    openssh.authorizedKeys.keys = [
      "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIAeN3T1aZkTm5xS0b66cRDyKUbdEQCFyzVWXeW+eIbsa chaos@chaos"
    ];
  };
  boot.loader.grub.enable = true;
  boot.loader.grub.device = "/dev/sda";
  boot.initrd.kernelModules = [ "nvme" ];

  services.openssh.enable = true;

  networking.enableIPv6 = true;
  networking.usePredictableInterfaceNames = false;
  networking.dhcpcd.enable = true;
  systemd.network = {
    enable = true;
    networks.eth0 = {
      name = "eth0";
      address = [ "2a01:4f9:c010:8beb::1/64" ];
      gateway = [ "fe80::1" ];
    };
  };

  system.stateVersion = "21.11"; 
}

Then run nixos-install and reboot if successful.

Step 4

Redeploy with deploy -s .#hetzner-vm --magic-rollback=false --auto-rollback=false --ssh-user root

Step 5

Restore using restic. B2_ACCOUNT_ID=id B2_ACCOUNT_KEY=key RESTIC_REPOSITORY=b2:Chaos-Backups:HetznerVM restic restore latest

Step 6

re-connect to tailscale tailscale up and redo dns

Step 7

Restore Postgres cat /var/backup/postgresql/all.sql.zstd | zstd -d | sudo -u postgres psql

Step 8

Restore music, either via mkdir -p /storage/music && env B2_ACCOUNT_ID=id B2_ACCOUNT_KEY=key RESTIC_REPOSITORY=b2:Chaos-Backups:Music restic restore latest --target /storage/music or ./sync.sh on laptop.
