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.5.4.0"), which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.
