trueDry install with the current Coq version:
opam install -y --show-action coq-tortoise-hare-algorithm.8.5.0 coq.8.6[NOTE] Package coq is already installed (current version is 8.6).
The following dependencies couldn't be met:
- coq-tortoise-hare-algorithm -> coq < 8.6~ -> ocaml < 4.03.0
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-tortoise-hare-algorithm.8.5.0truetrueNo files were installed.
