Dry install ๐Ÿœ๏ธ

Dry install with the current Coq version:

Command
opam install -y --show-action coq-mathcomp-sum-of-two-square.1.0.1 coq.8.11.1
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.11.1).
The following dependencies couldn't be met:
  - coq-mathcomp-sum-of-two-square -> coq-mathcomp-ssreflect < 1.9~ -> 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-mathcomp-sum-of-two-square.1.0.1
