Dry install with the current Coq version:
opam install -y --show-action coq-switch.1.0.4 coq.dev
[NOTE] Package coq is already installed (current version is dev). The following dependencies couldn't be met: - coq-switch -> coq-metacoq-template < 1.0~beta2+8.12 -> ocaml < 4.10 base of this switch (use `--unlock-base' to force) - coq-switch -> coq-metacoq-template < 1.0~beta2+8.12 -> coq < 8.13~ -> ocaml < 4.12 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.1.0.4
