AttributeError: 'CachedSession' object has no attribute 'remove_expired_responses'

[cweiske]

When running tvnamer on Debian 12 I get:

2024-10-11 16:15:32,483 - requests_cache.backends.sqlite - DEBUG - Opening connection to /tmp/tvdb_api--u1000-py3.sqlite:redirects

AttributeError: 'CachedSession' object has no attribute 'remove_expired_responses'

This is probably because the python3-requests-cache package

It looks like CachedSession.remove_expired_responses() was deprecated in 1.0.0 and removed in 1.2.0

as described in https://aur.archlinux.org/packages/plover_plugins_manager#comment-988008

now also affecting tvnamer 3.0.4 on ubuntu 25.04 (in late beta). Error stack trace is slightly different in a way that probably doesn't matter:

Knowing Ubuntu, the tvnamer universe package probably won't get an update in 25.04's lifetime, so I'd expect to be installing one outside of normal package management if it promised a fix, but just at the moment, it's got the latest version.
