PySide6 & WSL2: ImportError: libEGL.so.1

Question

I'm using isolated with poetry/venv Python: 3.11.2 with Ubuntu WSL2 22.04

python app.py

Gives me the following error:

Traceback (most recent call last):
  File "/home/lara/projects/qtapp/app.py", line 4, in <module>
    from PySide6.QtGui import QGuiApplication
ImportError: libEGL.so.1: cannot open shared object file: No such file or directory

app.py:

from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine

app = QGuiApplication()
engine = QQmlApplicationEngine()

engine.load("myqmlfile.qml")

app.exec()

Answer 1

You can search packages.ubuntu.com to figure out which package provides a certain file. In this case it's libegl1. Install it in WSL with:

apt install libegl1
