lwt_direct.6.0.0~beta00 is not installed. Install it? [Y/n] y
  * Incompatible packages:
    - (invariant) -> ocaml-options-only-nnpchecker -> ocaml-option-nnpchecker
    - lwt_direct >= 6.0.0~beta00 -> ocaml >= 5.0 -> ocaml-base-compiler >= 5.0.0~ -> ocaml-options-vanilla
    You can temporarily relax the switch invariant with `--update-invariant'
  * Missing dependency:
    - lwt_direct >= 6.0.0~beta00 -> ocaml >= 5.0 -> dkml-base-compiler >= 5.4.1~ | ocaml-base-compiler >= 5.4.1~ | ocaml-system >= 5.4.1~ | ocaml-variants >= 5.4.1~
