Configuring from /home/opam/.opamrc and then from built-in defaults.
Checking for available remotes: rsync and local, git.
- you won't be able to use mercurial repositories unless you install the hg command on your system.
- you won't be able to use darcs repositories unless you install the darcs command on your system.
This version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.2, which can't be reverted.
You may want to back it up before going further.

Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).
However, you may "opam upgrade" these packages explicitly at these versions (e.g. "opam upgrade ocaml.5.3.0"), 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 5.2.1+afl ocaml-variants.5.2.1+options ocaml-option-afl
# To update the current shell environment, run: eval $(opam env)
