MarsSeed [1] filed a deletion request for python2-stsci.distutils [2]: This Space Telescope related Python 2 distutils extension is essentially dead (missing a dependency).
I suggest deletion; only Python 3 works now for astronomy packages. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-stsci.distutils/
