** 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. - + 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 + * 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). ``` $ apt show displaycal | grep Depends WARNING: apt does not have a stable CLI interface.
