rafaelff [1] filed a deletion request for python-ruamel-yaml0.15.52 [2]: This package is not needed anymore. I created this package because buildstream depends on ruamel.yaml older than the version on official repositories (currently, 0.15.85). However, I misread 'ruamel.yaml < 0.15.52' thinking that 0.15.52 would satisfy the dependency, but 0.15.51 is the maximum allowed. Now that I uploaded a 0.15.51 version of ruamel.yaml, this package is not necessary and can be removed.
