# Updating the System

With Flakes, updating the system is straightforward. Simply execute the following commands in `/etc/nixos` or any other location where you keep the configuration:

```shell
# Update flake.lock
nix flake update

# Apply the updates
sudo nixos-rebuild switch --flake .
```

Occasionally, you may encounter a "sha256 mismatch" error when running `nixos-rebuild switch`. This error can be resolved by updating `flake.lock` using `nix flake update`.
