FS-UAE Launcher does not work in Fedora 29 - too new Python - here is workaround

[Goingdown]

Fedora 29 uses python 3.7, which seems to be too new for fs-uae-launcher, I got error in startup:

fs-uae-launcher
Traceback (most recent call last):
  File "/usr/local/bin/fs-uae-launcher", line 84, in <module>
    main()
  File "/usr/local/bin/fs-uae-launcher", line 80, in main
    import launcher.apps
  File "/usr/local/share/fs-uae-launcher/launcher/apps/__init__.py", line 4, in <module>
    import fstd.typing
  File "/usr/local/share/fs-uae-launcher/fstd/typing.py", line 1250, in <module>
    class Callable(extra=collections_abc.Callable, metaclass = CallableMeta):
  File "/usr/local/share/fs-uae-launcher/fstd/typing.py", line 961, in __new__
    self._abc_registry = extra._abc_registry
AttributeError: type object 'Callable' has no attribute '_abc_registry'

IT seems that because since Python 3.6 -> typing library is provided and it conflicts then.


Workaround was modify file launcher/apps/__init__.py file and comment out two lines:


#import fstd.typing
#sys.modules["typing"] = fstd.typing



Of course to do this right it should check python version first...


Another problem with Fedora 29 was that async is now reserved word in Python 3.7 and there is python file async.py which needed to be renamed to _async.py

I updated my Fedora COPR for Fedora 29.
