Output
[NOTE] Package coq is already installed (current version is dev).
[ERROR] Package conflict!
  * No agreement on the version of coq:
    - coq >= dev
    - coq-bignums = 8.15.0 -> coq < 8.16~
  * No agreement on the version of ocaml:

    You can temporarily relax the switch invariant with `--update-invariant'
