awso-sync.0.9.0 is not installed. Install it? [Y/n] y
  * Incompatible packages:
    - (invariant) -> ocaml-variants = 4.14.3+options
    - awso-sync -> ocaml >= 5.3.0 -> ocaml-base-compiler (< 5.3.1~ | >= 5.4.0~)
    You can temporarily relax the switch invariant with `--update-invariant'
  * Missing dependency:
