** Description changed:
[Impact]
DisplayCAL, when released, was only compatible with Python 3.8-3.11.
However, all it needed was WxWidgets 4.1.1 and a few patches to make it
work with Python 3.12. Without, it would simply fail. Namely, it needed
to be patched to remove the Python version check upon launch.
[Test Case]
* Install displaycal
* Run displaycal
Expected: Run normally
Result:
Traceback (most recent call last):
File "/usr/bin/displaycal", line 4, in <module>
from DisplayCAL.main import main
File "/usr/lib/python3/dist-packages/DisplayCAL/main.py", line 27, in
<module>
raise RuntimeError(
RuntimeError: Need Python version >= 3.8 <= 3.11, got 3.12.2
[What could go wrong]
The DisplayCAL developers do not yet support Python 3.12 until the
release of WxWidgets 4.2.0 since it could crash upon closure. I (Erich
Eickmeyer) have not experienced this in my testing, however, it is
plausible. Additionally, the patches that were used to make this work
were developed after the release of DisplayCAL 3.9.12, but still applied
cleanly to 3.9.11 and made it function correctly.
To be clear, the issue with WxWidgets is a separate bug and outside the
scope of this bug.
[Other Information]
Currently the tests have to be skipped otherwise they segfault with
- Python 3.12 and the entire source FTBFS, hence the inclusion of the
- patch `05_skip-test-wioth-python-3.12.patch`.

Original bug report:
I have upgraded to the noble beta today, and displaycal fails to start.
The package dependencies request python 3.12, but the actual software
needs 3.11 (or older).
