Everything as up-to-date as possible
However, you may "opam upgrade" these packages explicitly at these versions (e.g. "opam upgrade ocaml.5.5.0"), which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.

=> afl-persistent is installed, but since the current OCaml compiler does
not enable AFL instrumentation by default, most packages will not be
instrumented and fuzzing with afl-fuzz may not be effective.


To globally enable AFL instrumentation, create an OCaml switch like:
