trueDry install with the current Coq version:

The following dependencies couldn't be met:

No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-gaia-hydras.0.9truetrueNo files were installed.
