MarsSeed [1] filed a deletion request for nmclient2 [2]: Unmaintained since 2016. Source 404. Novell Messenger 2.2 was discontinued after 2014. Novell Messenger 3.0 got further developed to become Novell GroupWise Messenger. Safe to delete this obsolete NM2-based package, original maintainer disowned it because of lack of need to keep it alive.
