Dry install 🏜️

Dry install with the current Coq version:

Command

opam install -y --show-action coq-cfml-basis.20211215 coq.8.7.1+2

Return code

5120

Output

[NOTE] Package coq is already installed (current version is 8.7.1+2).
The following dependencies couldn't be met:
  - coq-cfml-basis -> coq >= 8.13 -> ocaml >= 4.05.0
      base of this switch (use `--unlock-base' to force)
  - coq-cfml-basis -> coq >= 8.13 -> 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-cfml-basis.20211215
