Exception during validation

[pkaczynski]

Validation steps always ends like this. Is python 3.8 supported?

Traceback (most recent call last):
  File "c:\programdata\miniconda3\lib\multiprocessing\pool.py", line 125, in worker
    result = (True, func(*args, **kwds))
  File "c:\programdata\miniconda3\lib\multiprocessing\pool.py", line 48, in mapstar
    return list(map(*args))
  File "c:\programdata\miniconda3\lib\site-packages\conda_mirror\conda_mirror.py", line 650, in _validate_or_remove_package
    logger.info('Validating {:4d} of {:4d}: {}.'.format(num + 1, num_packages,
AttributeError: 'NoneType' object has no attribute 'info'
"""

The above exception was the direct cause of the following exception:

I got this too, try --num-threads 1, the problem is with the multi threading

I don't have a Windows machine to test this on, but was this fixed (or at least worked around) in 4ff5189?
