However, if you install Python 3.14 and use that as your system defaults (NOT advised), you will replicate this error. This issue was originally discovered because downstream in Ubuntu for Ubuntu 26.04 development cycle, we use Python 3.14 down there. Thus showing the Python 3.14 issues here. --- When trying to run `galternatives` in a Python 3.14 environment, we are met with the following crash and failure to execute the software: Traceback (most recent call last):   File "/usr/bin/galternatives", line 6, in <module>     runpy.run_module('galternatives', run_name='__main__')     ~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^   File "<frozen runpy>", line 229, in run_module   File "<frozen runpy>", line 88, in _run_code   File "/usr/lib/python3/dist-packages/galternatives/__main__.py", line 12, in <module>     from galternatives.app import GAlternativesApp   File "/usr/lib/python3/dist-packages/galternatives/app.py", line 19, in <module>     from .alternative import AltDB, AltGroup, AltOption, CommandResult   File "/usr/lib/python3/dist-packages/galternatives/alternative.py", line 55, in <module>     class AltOption(dict[str, str]):     ...<71 lines>...                 for i in range(len(group)))   File "/usr/lib/python3/dist-packages/galternatives/alternative.py", line 65, in AltOption     __slots__ = tuple(__annotations__)                       ^^^^^^^^^^^^^^^ NameError: name '__annotations__' is not defined --- Upon examination of Python Best Practices [1], it is suggested that `annotationlib.get_annotations()` be used wherever a direct `__annotations__` reference is made. However, this cannot be done bare, it has to refer to the object itself. Additionally, __annotations__ isn't defined by default for classes anymore, and thus attempting to set `__slots__` before instantiation with `__init__` does not work. Downstream, and after an hour of poking, changes to set `__slots__` during initialization made it capable to fix this issue. A patch via Merge Request has been made available on Salsa, without d/changelog entries.
