Dry install 🏜️

Dry install with the current Coq version:

Command

opam install -y --show-action coq-relation-algebra.1.7.3 coq.8.13.1

Return code

5120

Output

[NOTE] Package coq is already installed (current version is 8.13.1).
The following dependencies couldn't be met:
  - coq-relation-algebra -> coq < 8.12~ -> ocaml < 4.12
      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-relation-algebra.1.7.3
