Difficult to say without knowing more about your system and the workflow. Looks like you are on Ubuntu Jammy (verify by running lsb_release -cs first. If you are not on Jammy then you'll have to change the name in Step 4. Try the workflow step-by-step and make sure you have not missed any step.

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted (core dumped)

I got this error after running the qgis_process command, after installing qgis in Ubuntu EC2 instance. Is it bcoz I am installing in an EC2 instance?

@ajigeo You may have better luck installing QGIS using conda https://gisunchained.wordpress.com/2019/05/29/using-qgis-from-conda/

You will need to specify the exact version number which you will get from https://anaconda.org/conda-forge/qgis/labels. Install miniconda, create an environment and run a command like

conda install -c conda-forge qgis=3.34.11
