python-ecdsa fails to build with Python 3.11.0a1.

Traceback (most recent call last):

AttributeError: module 'configparser' has no attribute 'SafeConfigParser'. Did you mean: 'RawConfigParser'?

Removed from the configparser module: the SafeConfigParser class, the filename
property of the ParsingError class, the readfp() method of the ConfigParser
class, deprecated since Python 3.2. (Contributed by Hugo van Kemenade in

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.11:

Let us know here if you have any questions.

Python 3.11 is already included in Fedora 35. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
