Dry install with the current Coq version:

- Command
`opam install -y --show-action coq-cats-in-zfc.8.8.0 coq.dev`

- Return code
- 5120
- Output
[NOTE] Package coq is already installed (current version is dev). The following dependencies couldn't be met: - coq-cats-in-zfc -> coq < 8.9~ -> 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:

- Command
`opam remove -y coq; opam install -y --show-action --unlock-base coq-cats-in-zfc.8.8.0`
