MarsSeed [1] filed a deletion request for python2-pyupcean [2]: Broken package from 2019 for an unused Python2 library.
I recommend deletion as nothing depends on it. Upstream supports Python3; there's an AUR package for it. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-pyupcean/
