Dry install 🏜️

Dry install with the current Coq version:

Command

opam install -y --show-action coq-euler-formula.8.9.0 coq.8.14.0

Return code

5120

Output

[NOTE] Package coq is already installed (current version is 8.14.0).
The following dependencies couldn't be met:
  - coq-euler-formula -> coq < 8.10~ -> ocaml < 4.10
      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:

Command: opam remove -y coq; opam install -y --show-action --unlock-base coq-euler-formula.8.9.0
