# Upgrade Ubuntu image

This guide walks you through a streamlined process to update your system using prebuilt packages, while preserving your existing environment. The update is performed from a host computer—running Ubuntu, Windows®, or macOS®—to ensure your device benefits from the latest improvements in performance, security, and compatibility.

**Prerequisites:** Before You Start - Complete [**🔗 Set up the device**](../set-up-the-device) instructions.

## Login & Wi-Fi Connection

**a.** Login and change password (if not yet changed) on an attached monitor using a keyboard and mouse, or via the UART console if connected over serial.

* Sign in to the Dragonwing IQ-9075 EVK Ubuntu UART console, using **ubuntu** as both the username and password. Then, you can reset the password in your command terminal.
* After successful login, you will see the following serial console prompt.

**b.** Set up Wi-Fi connectivity by following these steps:  [🔗 **Wi-Fi Setup Guide**](../set-up-the-device#wi-fi)

## SSH Connection

SSH facilitates secure terminal access across a network between the host computer and the Dragonwing IQ-9075 device.

Before you connect to SSH, ensure that your device has network connectivity through Ethernet or Wi-Fi.

<Note>**Note:**  Ensure that the remote host computer connects to the same Wi-Fi access point as the device.</Note>

**a.** To connect to SSH, first find the IP address of the Dragonwing IQ-9075 by running the appropriate command on the UART console of the host computer, based on the network connection type:

For Ethernet:

```shell theme={null}
ip addr show end0
```

For Wi-Fi:

```shell theme={null}
ip addr show wlp1s0
```

This command displays the IP address of the Dragonwing IQ-9075 device.

**b.** Establish an SSH connection to the device from the host computer by running the following command:

```shell theme={null}
ssh ubuntu@ip-address
```

**Details of the Parameters**\
The ip-address is the IP address of eth0 or wlan0 interface.

**Example**\
To connect to a device with IP address 192.168.0.222, run the following command:

```shell theme={null}
ssh ubuntu@192.168.0.222
```

**c.** Login by entering the password for the *ubuntu* user.

## Verify the SW version

Run the following commands in the device shell to verify the OS version:

```shell theme={null}
cat /etc/os-release 
```

**Output:**

```json theme={null}
PRETTY_NAME="Ubuntu 24.04.4 LTS"
NAME="Ubuntu"
VERSION_ID="24.04"
VERSION="24.04.4 LTS (Noble Numbat)"

```

Run the following command to check the Linux kernel version:

```shell theme={null}
uname -a
```

**Output:**

```json theme={null}
