This version of opam requires an update to the layout of /Users/mac1000/.opam from version 2.1 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).


The following packages are not being upgraded because the new versions conflict with other installed packages:
- ocaml.5.5.0
- ocaml-compiler.5.5
-- ocaml-base-compiler.5.4.0~alpha1 is installed and requires ocaml-compiler = 5.4.0~alpha1
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.
