# 🌐 Set System Language/Locale to en_US.UTF-8 (Required for ggRock)

### ❗ Problem

The ggRock Server Application **requires the system locale to be set to** `en_US.UTF-8` to function properly. Using a different locale may cause:

* Errors on the **Arrays** tab
* Unexpected or broken behavior in other parts of the application

---

### ✅ Solution

Follow the steps below to change your Debian system locale:

---

### 🔐 Step 1: Log in to the Server

You can access the server as `root` using one of the following methods:

* **Debian Control Panel**
* **SSH**
* **Direct physical access**

---

### 💻 Step 2: Reconfigure Locales

Run the following command in the terminal:

```
dpkg-reconfigure locales
```

---

### 🧭 Step 3: Select `en_US.UTF-8`

On the **"Configuring locales"** screen:

1. Use the **arrow keys** to scroll to:

```
   [ ] en_US.UTF-8 UTF-8
```
2. Press the **Space Bar** to select it:

```
   [*] en_US.UTF-8 UTF-8
```

> If it's already selected, proceed to the next step.

---

### 🌍 Step 4: Set Default System Locale

From the same configuration tool:

* Press **Enter** to confirm

---

### 🔁 Step 5: Reboot the Server

After completing the steps above, **reboot the server**:

```
reboot
```

Then, check the **Arrays** tab in the ggRock web interface to ensure it's working as expected.

### 📘 Additional Info
|| The ggRock Server Application relies on standardized datetime and command output formatting from Debian. These outputs vary depending on the system locale, which is why en_US.UTF-8 is currently required.
> ⚙️ Our development team is aware of the issue and working on solutions that will remove the need for this locale requirement in the future.
