[INFO] opam 2.5.1 includes security fixes; please consider upgrading (https://opam.ocaml.org/doc/Install.html)


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
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.
