MarsSeed [1] filed a deletion request for cura-5-modern-beta-bin [2]: This is currently the same version, 5.4.0, as the stable cura-bin.
If needed, please resubmit later without the pinned major version 5 in the name: cura-modern-beta-bin. (There is no point in pinning the major version number in the beta package name. Also, upstream does not maintain parallel major releases.) [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/cura-5-modern-beta-bin/
