You have the same wheel name there twice. I'm assuming you meant PyQt6<br>
(rather than PyQt6-Qt6) in the first sentence?<br>

<br>
This is a Qt limitation. PyQt wheels ship Qt's official binaries, and<br>
those only work with glibc 2.28+:<br>
<a href="https://doc.qt.io/qt-6/supported-platforms.html" rel="noreferrer" \
target="_blank">https://doc.qt.io/qt-6/supported-platforms.html</a><br> <br>
Note: Linux binary packages are linked against glibc 2.28. If you<br>
are using a glibc version older than that you need to build Qt from<br>
sources or upgrade glibc to 2.28 or newer.<br>
