Dry install with the current Coq version:
opam install -y --show-action coq-switch.1.0.2 coq.8.13.1
[NOTE] Package coq is already installed (current version is 8.13.1). The following dependencies couldn't be met: - coq-switch -> coq-metacoq-template < 1.0~beta1 -> coq < 8.12~ -> ocaml < 4.06.0 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-switch.1.0.2
