Output
[NOTE] Package coq is already installed (current version is 8.5.0~camlp4).
The following dependencies couldn't be met:
  - coq-demos -> coq >= 8.9 -> ocaml >= 4.05.0
      base of this switch (use `--unlock-base' to force)
  - coq-demos -> coq >= 8.9 -> coq-core -> ocaml >= 4.09.0
      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

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-demos.8.9.0
