MarsSeed [1] filed a deletion request for python2-plac-git [2]: Unneeded Python2 VCS package from 2015. The source repo used has not been updated since 2010. [a]
There's a newer fork of this that supports Python3; AUR has a maintained stable package for that. [a]: https://github.com/kennethreitz-archive/plac [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-plac-git/
