Comment 16 for bug 1529450

Just wondering why ubiquity-frontend-kde only has depends on
python3-pyqt4 (Python3 bindings for Qt4)
instead of/or additionally on
python3-pyqt5. This may be fine for someone coming from 12.04LTS but Vivid/Wily have Qt5 already.

Same applies than for python3-dbus.mainloop.qt (D-Bus Support for PyQt4 with Python 3)

> What is PyQt?

PyQt is a set of Python v2 and v3 bindings for The Qt Company's Qt application framework and runs on all platforms supported by Qt including Windows, MacOS/X and Linux. PyQt5 supports Qt v5. PyQt4 supports Qt v4 and will build against Qt v5. The bindings are implemented as a set of Python modules and contain over 1,000 classes.

The Qt Company have announced that support for Qt v4 will cease at the end of 2015. PyQt5 and Qt v5 are strongly recommended for all new development. ... <

Exuses if I'm wrong with my guess in comment #6 here, but I see some similarity as with the shift from Phython2/Phython3.
