# 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:
|
|
|
|
> **NOTE**: The `/etc/nixos` directory is owned by and only writable to `root`. Therefore,
|
|
> if your flake is located in this directory, you'll need to use `sudo` to update any
|
|
> configuration files.
|
|
|
|
```shell
|
|
# Update flake.lock
|
|
nix flake update
|
|
|
|
# Or update only the specific input, such as home-manager:
|
|
nix flake update home-manager
|
|
|
|
# Apply the updates
|
|
sudo nixos-rebuild switch --flake .
|
|
|
|
# Or to update flake.lock & apply with one command (i.e. same as running "nix flake update" before)
|
|
sudo nixos-rebuild switch --recreate-lock-file --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`.
