MarsSeed [1] filed a deletion request for algodoo [2]: Broken Linux binary from or before 2015. Upstream discontinued providing Linux builds; they only publish Windows and Macintosh installers now. This package depends on broken, unmaintained legacy AUR builds. Better to delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/algodoo/
