Output

[NOTE] Package coq is already installed (current version is 8.11.2).
The following dependencies couldn't be met:
  - coq-flocq -> coq (< 8.11~ & >= 8.12) -> 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

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-flocq.3.4.1
