MarsSeed [1] filed a deletion request for cura-5-beta-bin [2]: As of now this is the same version as cura-bin (latest 5.4.0 stable). If needed, resubmit a new beta package under the proper name, 'cura- beta-bin'. There is no point in pinning the major version in a beta package. Upstream does not maintain parallel major versions.
