rafaelff [1] filed a deletion request for python-ruamel-yaml0.15.51 [2]: This package is not needed anymore. It was created to satisfy a depedency of BuildStream (another package I maintain) for a ruamel.yaml<=0.15.51 when official repos' version was 0.16+; now BuildStream can use the ruamel.yaml 0.16+.
