Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-mathcomp-sum-of-two-square.1.0.0 coq.8.12.2
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.12.2).
The following dependencies couldn't be met:
  - coq-mathcomp-sum-of-two-square -> coq-mathcomp-ssreflect < 1.7 -> coq < 8.8~ -> ocaml < 4.06.0
      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:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-mathcomp-sum-of-two-square.1.0.0
