MarsSeed [1] filed a deletion request for python2-argon2 [2]: Deprecated in 2015, not needed anymore. Superseded by argon2-cffi. Its only AUR consumer, python2-pykeepass also needs the latter. (Currently doesn't even work, needs update to fix dependencies.) So it's safe to delete this one. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-argon2/
