  • Undo: Do not perform the offending transaction (do not install the package that had unsatisfied requirements, do not remove the package that would break other packages' requirements)

  • Remove referrers: Remove all packages that would break because they depend on the package that is requested to be removed

  • Ignore: Inject artificial "provides" for a missing requirement (pretend that requirement is satisfied)
