Hi!

As you might know, we the Qt/KDE team are going to remove Qt 4 in Bullseye
cycle, as announced in [1].

In order to make this move, all packages directly or indirectly depending on
the Qt4 libraries have to either get ported to Qt5 or eventually get removed
from the Debian repositories.

Your package still uses Qt 4, via the Python bindings (PyQt4).

Therefore, please take the time and:

- contact your upstream (if existing) and ask about the state of a Qt 5 /
  PyQt5 port of your application;
- if there are no activities regarding porting, investigate whether there are
  suitable alternatives for your users;
- if there is a Qt 5 port that is not yet packaged, consider packaging it;
- if both the Qt 4 and the Qt 5 versions already coexist in the Debian
  archives, consider removing the Qt 4 version.

Porting from Qt 4 to 5 is much easier than it was to port from Qt 3 to 4.
Please see [2] for the general porting instructions, and [3] for some
Python-specific differences.

The removal is being tracked in [4]. My intention is to bump the severity
of this bug to RC soon, like it is already the case with other Qt 4 removal
bugs.
