MarsSeed [1] filed a deletion request for oqapy [2]: EOL for 7 years, has been broken since 4 years ago. (Tested 1-2 months back, same result.) And now upstream has even deleted the source (404). Not viable or useful to keep. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/oqapy/
