Dry install with the current Coq version:
opam install -y --show-action coq-io-system-ocaml.2.3.1 coq.8.14.0
[NOTE] Package coq is already installed (current version is 8.14.0). The following dependencies couldn't be met: - coq-io-system-ocaml -> lwt < 5 -> ocaml < 4.12 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-io-system-ocaml.2.3.1
