rafaelff [1] filed a deletion request for koreader-bin [2]: Out-of-date for some time without answer of the maintainer, and it provides the same content as the 'koreader-appimage' package, which is up-to-date. Note that the upstream releases in several packages, so -bin or -appimage doesn't make difference.
