Ubuntu – Installing PYTHON3.8 and PyQt5 to the DOCKER CONTAINER with using DOCKERFILE

I have a project that contains a lot of library (requirements.txt) and I want to create a dockerfıle when I build this docker file in docker container I need python3.8 and ın python3.8 I need PyQt5 library.

When I create a simple dockerfile just consist of

FROM ubuntu:22.04

COPY . /app

The problem that I facing is when I try:

apt-get install python3-pyqt5

PyQt5 install python3.11 or python 3.10 and install PyQt5 in this directory.

But my project only run in python3.8 what should I do ?

    I have uploaded the file Dockerfile like this because I need the architecture of the container arm64

    FROM --platform=linux/arm64 python:3.8.10-slim
COPY . /app
ENV LIBGL_ALWAYS_INDIRECT=1unam

    but now I cant install pyqt5 library using

    apt-get install python3-pyqt5

    code in the container. Container give's me the error that is
