Output

[NOTE] Package coq is already installed (current version is 8.11.dev).
The following dependencies couldn't be met:
  - coq-cheerios -> coq (< 8.11~ & = dev) -> ocaml < 4.05.0
      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:
