Dry install with the current Coq version:
opam install -y --show-action coq-higman-s.8.7.0 coq.8.4.6~camlp4
[NOTE] Package coq is already installed (current version is 8.4.6~camlp4). The following dependencies couldn't be met: - coq-higman-s -> coq >= 8.7 -> ocaml >= 4.05.0 base of this switch (use `--unlock-base' to force) - coq-higman-s -> coq >= 8.7 -> coq-core -> ocaml >= 4.09.0 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:
opam remove -y coq; opam install -y --show-action --unlock-base coq-higman-s.8.7.0
