Dry install with the current Coq version:
opam install -y --show-action coq-higman-s.8.5.0 coq.8.12.2
[NOTE] Package coq is already installed (current version is 8.12.2). The following dependencies couldn't be met: - coq-higman-s -> coq < 8.6~ -> ocaml < 4.06.0 base of this switch (use `--unlock-base' to force) No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-higman-s.8.5.0
