yochananmarqos [1] filed a deletion request for cosmic-epoch-git [2]: Upstream is not updating this package anymore as it is not a supported method to test the new Cosmic Desktop Environment. See my pinned comment: https://aur.archlinux.org/packages/cosmic-epoch- git#comment-981685 I already maintain all the packages separately now, so this package should no longer be used.
