MarsSeed [1] filed a deletion request for mpn [2]: Hi, It seems this Python 2 tool got discontinued 11 years ago, in 2011. Package is now broken due to missing Py2 deps. So I suggest to delete this. Safe to do so: nothing depends on it anymore. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/mpn/
