Output

[NOTE] Package coq is already installed (current version is 8.5.2~camlp4).
The following dependencies couldn't be met:
  - coq-gaia-stern -> coq >= 8.16 -> ocaml >= 4.09.0
      base of this switch (use `--unlock-base' to force)
  - coq-gaia-stern -> coq >= 8.16 -> coq-core -> ocaml >= 4.09.0
      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-gaia-stern.2.0
