MarsSeed [1] filed a deletion request for python-skymapper-git [2]: Abandoned, broken niche Python2/Python3 VCS package from 2019.
Seems there is no active interest by users in maintaining or using it. Latest upstream version can be quickly installed e.g. from PyPI. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-skymapper-git/
