[Pkg-netmeasure-discuss] Bug#1089971: flent: python3-qtpy dropping dependency on PyQt5; Recommends may need updating

[Julian Gilbey]

Package: flent
Version: 2.2.0-1
Severity: important
User: python3-qtpy at packages.debian.org
Usertags: drop-qt5
Control: block 1070215 by -1

Dear Maintainer,

Your binary package flent currently Recommends python3-qtpy.

The upstream qtpy package is intended to be a metapackage, able to
work with any of PyQt5, PyQt6, PySide2 or PySide6 as the Qt backend.
Until now, the Debian python3-qtpy package has Depended on PyQt5, but
that is about to change.  From version 2.4.2-3 of python3-qtpy
(currently in experimental), it no longer Depends on any Qt backend,
so these will need to be explicitly listed in the package's Depends
field.  To help, there are also new metapackages python3-qtpy-pyqt5,
python3-qtpy-pyqt6 and python3-qtpy-pyside6 already in testing that
depend on python3-qtpy and the respective Qt backend.

Action required: update the Recommends field to include the required
Qt backend packages.

Approach 1 (the "best" approach):

Identify the Python backend packages required and add these to
Recommends.  (These could be PyQt5 packages, but they could equally be
PyQt6 or PySide6 packages.)

Approach 2 (should work in all cases, but will pull in more than needed):

Add python3-qtpy-pyqt5 to the Recommends field, or replace the
existing python3-qtpy recommendation with python3-qtpy-pyqt5 (as the
latter Depends on python3-qtpy).  This will exactly replicate the
current behaviour.


I intend to upload python-qtpy 2.4.2-4 to unstable with this change in
mid-to-late January.  I will do an NMU or team upload if required for
this bug from mid-January.
