This version of opam requires an update to the layout of /home/opam/.opam from version 2.1 to version 2.2, which can't be reverted.

Everything as up-to-date as possible

The following packages are not being upgraded because the new versions conflict with other installed packages:
  - ocaml.5.5.0
  - ocaml-compiler.5.4.1+lrgrep
    -- ocaml-base-compiler.5.4.1 is installed and requires ocaml-compiler = 5.4.1
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:

     opam switch create 5.4.1+afl ocaml-variants.5.4.1+options ocaml-option-afl
# To update the current shell environment, run: eval $(opam env)
