After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: transformers, optparse-applicative, data-lens-template, base, template-haskell, tasty-quickcheck, transformers-test, transformers-test:test
Try running with --minimize-conflict-set to improve the error message.
