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.
You may want to back it up before going further.

stdcompat.20.0 is not installed. Install it? [Y/n] y
The following actions will be performed:
=== install 3 packages
  - install conf-autoconf 0.2           [required by stdcompat]
  - install dune          3.22.1        [required by stdcompat]
  - install stdcompat     20.0 (pinned)

The following system packages will first need to be installed:
    autoconf

<><> 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
