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.The following table lists the QIR SDK package to install for each Ubuntu variant.

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

Installing the wrong QIR SDK package causes 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 packageTo 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

For Ubuntu Server

sudo apt remove qirp-sdk-desktop
sudo apt install qirp-sdk
