Dry install with the current Coq version:

- Command
`opam install -y --show-action coq-higman-nw.8.6.0 coq.dev`

- Return code
- 5120
- Output
[NOTE] Package coq is already installed (current version is dev). The following dependencies couldn't be met: - coq-higman-nw -> coq < 8.7~ -> ocaml < 4.06.0 base of this switch (use `--unlock-base' to force) Your request can't be satisfied: - No available version of coq satisfies the constraints No solution found, exiting
