TypeError: 'type' object is not subscriptable

[SCGabriel]

I try to use nndownload.py v1.11.2 in Kubuntu 20.04,but it returns errors.

nndownload.py -u user -p password --proxy socks5://192.168.1.99:32233/ --force-high-quality --dump-metadata --download-thumbnail https://www.nicovideo.jp/watch/sm38318426

Traceback (most recent call last):
  File "/usr/local/bin/nndownload.py", line 1668, in <module>
    def process_url_mo(session, url_mo: re.Match[AnyStr]):

Maybe a type hint issue, I think it should be:

from typing import Match
[...]
def process_url_mo(session, url_mo: Match):

AlexAplin added the bug label 23 days ago

...and?

Just faced the same error, and almost abandoned the program, thinking it probably requires too new python3 (which my distro still doesn't have). But after changing the code as suggested, it at least appears to launch without errors, did not test the operation yet.
