<><> Updating package repositories ><><><><><><><><><><><><><><><><><><><><><><>
[default] Initialised
default (at git+file:///home/opam/opam-repository):
[INFO] opam 2.1 and 2.2 include many performance and security improvements over 2.0; please consider upgrading (https://opam.ocaml.org/doc/Install.html)


Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.
