Dry install with the current Coq version:

- Command
`opam install -y --show-action coq-propcalc.8.6.0 coq.8.11.dev`

- Return code
- 5120
- Output
[NOTE] Package coq is already installed (current version is 8.11.dev). The following dependencies couldn't be met: - coq-propcalc -> coq < 8.7~ -> 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-propcalc.8.6.0`
