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.

  - install csexp             1.5.2            [required by dune-configurator]
  - install dune              3.22.0           [required by libbinaryen]
  - install dune-configurator 3.22.0           [required by libbinaryen]
  - install libbinaryen       126.0.0 (pinned)

The following system packages will first need to be installed:

<><> Handling external dependencies <><><><><><><><><><><><><><><><><><><><><><>

opam believes some required external dependencies are missing. opam can:
> 1. Run apt-get to install them (may need root/sudo access)
  2. Display the recommended apt-get command and wait while you run it manually (e.g. in another terminal)
  3. Continue anyway, and, upon success, permanently register that this external dependency is present, but not detectable
  4. Abort the installation
