<p>I got the new Raspi 5 and tested a few things. I used pip to
install/modify a dozen packages, and all worked except for <b>PyQt5.</b></p>
<p>PyQt5 had been apt-installed as version 5.15.9, and worked in
tests of mine. But what failed was when trying to upgrade to
5.15.10. After closer instepction I apt-removed the apt-installed
PyQt5, and tried to pip-install that very same version. It failed
with :<br>
</p>
<p> Preparing metadata (pyproject.toml): started<br>
Preparing metadata (pyproject.toml): finished with status
'error'</p>
<p>Full error report in attached file.</p>
<p>After reinstalling 'python3-pyqt5' via apt, it worked again.</p>
<p>Where is the problem: Raspi, Debian, pip, pyqt5?</p>

<p>On Raspi 5 I used the default OS install:</p>
