I believe that plexus-graph package should be retired in Fedora rawhide. Reason: project has been retired upstream. I've checked and nothing requires or bulid-requires this package. Package owner: Can you retire the package in f23? Or if you prefer I can retire it - in this case just orphan the package and let me know and I will retire it myself.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Package plexus-graph was retired in rawhide.
