missing libxkbcommon-x11.so.0 => not found why??

I was investigating the cause of a matplotlib crashing on a remote system.

After much digging, the cause of the problem is that the PyQt5 ibqxcb.so needs a lot of stuff:

This system is built from an image in the virtual machine environement so it is strange that there are missing shared libraries that causes matplotlib to crash.

So question: i have built ubuntu 22 from liveCD and do not have this problem yet i use a image create by someone that make the system has lot of missing files. So how would one is capable to build an image with so many missing shared objects?
