Some developers reported that if you install Ubuntu 18.04 with secure boot, it will influence to install Nvidia GPU driver.

Using UltraISO on Windows or Ddsecure on Linux to install ISO on a USB stick.

Boot from USB stick, then install Ubuntu.

Using sudo to do other action.

Don't forget to install prebuilt dependencies after you finish to install Ubuntu:

{% content-ref url="/pages/-LwHr67g4qTmpgK1l8fm" %}
[GAAS prebuilt dependencies](/guide/handy-tools/gaas-prebuilt-package.md)
{% endcontent-ref %}

Due to the system restriction, the ROS components must be used under root user. Thus, execute

```
sudo su
```

Then run ROS command (such as `roscore` or `roslaunch`)

If you would like to use SLAM, please compile it first. 

```
cd （GAAS_PATH)/software/SLAM/ygz_slam_ros
sh generate.sh
```

Everything you need for SLAM has already been installed in the mirror.

`/root/Firmware`is the PX4 Firmware
