Error when running LucasR.py on WSL 2

[CheckDaniels]

I am currently working in Ubunut 22.04.3 LTS with WSL (in Windows 11). I followed the instructions "https://lucaschess.blogspot.com/2021/07/linux-tutorial-for-creating-installer.html", but when I tried to run the LucasR.py file, I got the following output.

check@LAPTOP-LU8L3B35:~/lucaschessR2-main/bin$ python3 LucasR.py
Traceback (most recent call last):

    from PySide2 import QtCore, QtWidgets, QtGui
ImportError: libGL.so.1: cannot open shared object file: No such file or directory

I even tried installing libxcb-xinerama0 as described in the instructions. It still didn't change much.

check@LAPTOP-LU8L3B35:~$ sudo apt-get install libxcb-xinerama0

libxcb-xinerama0 is already the newest version (1.14-3ubuntu3).
The following packages were automatically installed and are no longer required:
  libpython2-stdlib libpython2.7-minimal libpython2.7-stdlib python-pkg-resources python-setuptools python2 python2-minimal python2.7 python2.7-minimal
Use 'sudo apt autoremove' to remove them.

I'm using:

• pip 23.1.2
• WSL 2
• Ubunut 22.04.3 LTS
• LucaschessR2-main

Perhaps: apt-get update && apt-get install libgl1

Thanks I think it helped a little, but now I'm running into following error:

ImportError: libpulse-mainloop-glib.so.0: cannot open shared object file: No such file or directory

The error seems to me being similar to this one: [(https://github.com/lukasmonk/lucaschessR2/issues/62)]

[lukasmonk]

I created the version from scratch and for Ubuntu: sudo apt-get install libxcb-xinerama0

In your case, perhaps (search with google): sudo apt-get install -y libpulse-mainloop-glib0

[CheckDaniels]

It finnaly workedヽ(•‿•)ノ.

What I did: I installed as you said "libpulse-mainloop-glib0" and ran LucasR.py, but then I got a new Error

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)

After a little research. I came across this:. So I added following into the console: export QT_DEBUG_PLUGINS=1 and ran it again. The Error-Output was now more detailed. The end of the error looked like this.

Apparently not all packages from the xcb libary were installed (see here). To see what packages were missing I wen to the package folder, in my case: cd .local/lib/python3.8/site-packages/PySide2/Qt/plugins/platforms and run following command. ldd libqxcb.so This gave me a list of all installed/missing packages (see here)

I now just installed them seperately (for this I just asked ChatGPT): sudo apt install libxcb1 libxcb-icccm4 libxcb-util1 libxcb-keysyms1 libxcb-render-util0 libxcb-xkb1 libxkbcommon-x11-0 libxcb-image0 libxcb-util1 libxcb-keysyms1 libxcb-render-util0 libxcb-xkb1 libxkbcommon-x11-0

and ran LucasR.py again and it started.

Good work!
