This error can be daunting, especially when it halts your progress. However, with the right understanding and fix, you can quickly move past this issue. Let’s break down what's happening and how to resolve it efficiently.

Understanding the Problem

What Causes the Error?

The error originates when the pyquery library attempts to utilize the lxml library for its XML and HTML parsing. Specifically, it indicates a missing symbol (xsltGetProfileInformation) that is part of the XSLT functionalities provided by the libxslt package. Essentially, it means that while you have lxml installed and operational, it's also missing critical libraries that it relies on.

Most Common Scenario

This error is prevalent on systems like CoreELEC, which may not have traditional package managers like apt-get. As a result, it typically uses opkg, which can lead to oversight on required dependencies.

The Solution: Install the Missing Package

Step-by-Step Guide

Follow the steps below to fix the issue:

Check Installed Packages:
Start by ensuring you have the relevant packages installed. This includes python3-lxml and libxml2, which are essential for lxml to function.

Install Missing Dependencies:
You’ll need to install the libxslt package, which is the missing component that resolves the undefined symbol error. Use the following commands in your terminal:
