Dry install with the current Coq version:
opam install -y --show-action coq-ltac2.0.2 coq.8.8.2
[NOTE] Package coq is already installed (current version is 8.8.2). The following dependencies couldn't be met: - coq-ltac2 -> coq >= 8.9 -> ocaml >= 4.05.0 base of this switch (use `--unlock-base' to force) - coq-ltac2 -> coq >= 8.9 -> 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-ltac2.0.2
