Description of problem:
Fedora 22 is planning to switch over to dnf from yum as per
Please switch from yum/yum-utils to dnf/dnf-plugins-core. Thanks!
Seems that snake requires yum but yum is not uses anywhere in the code.
Please remove the require and rebuild package for F22 and rawhide.
Please could you provide a status of bug solving or future plans?
Sorry, but snake is abandoned / unmaintained. I didn't even know it was still in Fedora, actually.
If anyone *is* still using it, you have my blessing to fork it and maintain it yourself, but I have no plans (or time) to work on it.
