Configuring from /home/opam/.opamrc-sandbox, then /home/opam/.opamrc, and finally from built-in defaults.
Checking for available remotes: rsync and local, git.
  - you won't be able to use mercurial repositories unless you install the hg command on your system.
  - you won't be able to use darcs repositories unless you install the darcs command on your system.

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.

  * No agreement on the version of ocaml:
    - (invariant) -> ocaml-base-compiler = 4.14.2 -> ocaml = 4.14.2
    - melange = 6.0.1-53 -> ocaml >= 5.3
