Which QIR SDK package should I use for Ubuntu desktop or server?

The QIR SDK has two variants for the Ubuntu desktop and server respectively.

Table 46: QIR SDK for Ubuntu variants

| Ubuntu variant | QIR SDK package |
| --- | --- |
| Desktop | qirp-sdk-desktop |
| Server | qirp-sdk |

Note

Installing the wrong QIR SDK package cause different problems for Ubuntu desktop and server images:

- On the **desktop** image, using qirp-sdk can cause errors when running the QIR SDK sample applications and features.
- On the **server** image, using qirp-sdk-desktop works for most features but it misses these packages for server-only features such as colorspace conversion:

    - ros-jazzy-qrb-ros-colorspace-convert
    - ros-jazzy-qrb-colorspace-convert-lib

**Switch to the correct QIR SDK package**

To switch to the correct QIR package for each Ubuntu variant (Ubuntu server and Ubuntu desktop), run the following commands:

- **For Ubuntu Desktop**

> 
> 
> sudo apt remove qirp-sdk ros-jazzy-qrb-ros-colorspace-convert ros-jazzy-qrb-colorspace-convert-lib
>         sudo apt install libegl1 libgles2 ubuntu-desktop-minimal qirp-sdk-desktop
>         sudo reboot
>         Copy to clipboard
- **For Ubuntu Server**

> 
> 
> sudo apt remove qirp-sdk-desktop
>         sudo apt install qirp-sdk
>         Copy to clipboard
