problems with PyQt5-5.15.0 linux wheel

[Steve Borho]

Hello,

I’ve noticed something unusual about the PyQt5-5.15.0-5.15.0-cp35.cp36.cp37.cp38-abi3-manylinux2014_x86_64.whl wheel that is served by PyPi.

If you install it on Ubuntu 20.04 (py3.8) or Ubuntu 18.04(py3.6) it seems to be ok, but if you install it on Ubuntu 16.04 (py3.5) it does not install the Qt/plugin/ or Qt/translations/ folder like it does for the other Python versions.

This leads to runtime errors when you try to use PyQt5:

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.

I checked the PyQt5-5.14.2 wheel on Ubuntu 16.04 (py3.5) and it did install the plugins and translations, so this looks like a regression.

Regards,

Steve Borho
