MarsSeed [1] filed a deletion request for python-classutils [2]: Dead, abandoned package from 2022.
Upstream seems to be completely unmaintained for 2 years. The package is missing a nonexistent dependency, and it relies on python-future, which is terminally defunct on Python 3.13. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-classutils/
