trueDry install with the current Coq version:
opam install -y --show-action coq-tree-diameter.8.10.0 coq.8.9.0[NOTE] Package coq is already installed (current version is 8.9.0).
The following dependencies couldn't be met:
- coq-tree-diameter -> coq >= 8.10 -> ocaml >= 4.05.0
base of this switch (use `--unlock-base' to force)
- coq-tree-diameter -> coq >= 8.10 -> coq-core -> ocaml >= 4.09.0

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-tree-diameter.8.10.0truetrueNo files were installed.
