[_14] fail (backjumping, conflict set: amazonka, amazonka-core, stackctl,
unliftio-core)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: amazonka-core, aeson, lens, conduit,
http-conduit, primitive, lens-aeson, template-haskell, base, stackctl, yaml,
th-abstraction, amazonka, transformers, vector, unliftio-core, yaml:nolib
Try running with --minimize-conflict-set to improve the error message.
