[WARNING] opam is out-of-date. Please consider updating it (https://opam.ocaml.org/doc/Install.html)
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.5.4.0
- ocaml-config.3
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.
