DistributionNotFound error after update

[fnc]

Hi!

Recently I updated my system and a python application has stopped working, throwing the following error:

Traceback (most recent call last):
  File "/usr/bin/wallpaper-reddit", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 3243, in <module>
    def _initialize_master_working_set():
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 3226, in _call_aside
    f(*args, **kwargs)
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 3255, in _initialize_master_working_set
    working_set = WorkingSet._build_master()
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 568, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 886, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 772, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'wallpaper-reddit==3.1.1' distribution was not found and is required by the application´

I know that I have solved this issue in the past, but I can’t remember how or even why is happening. Can anyone help me please?

Thanks in advance.

Have you tried rebuilding the “offending” AUR package? That usually helps.

python3.9/site-packages

System Python has been updated to 3.9 - when your homebuild packages fails after an update - the recipe is to rebuild the package(s) just as @Strit recommends.
