trueDry install with the current Coq version:
opam install -y --show-action coq-euler-formula.8.6.0 coq.8.5.3[NOTE] Package coq is already installed (current version is 8.5.3).
The following dependencies couldn't be met:
- coq-euler-formula -> coq >= 8.6 -> ocaml >= 4.05.0
base of this switch (use `--unlock-base' to force)
- coq-euler-formula -> coq >= 8.6 -> coq-core -> ocaml >= 4.09.0

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-euler-formula.8.6.0truetrueNo files were installed.
