Dry install with the current Coq version:
opam install -y --show-action coq-io-hello-world.1.2.0 coq.8.13.1
[NOTE] Package coq is already installed (current version is 8.13.1). The following dependencies couldn't be met: - coq-io-hello-world -> coq-io-system-ocaml >= 2.3.0 -> ocaml < 4.06.0 base of this switch (use `--unlock-base' to force) - coq-io-hello-world -> coq-io-system-ocaml >= 2.3.0 -> 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-hello-world.1.2.0
