  - 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.

<><> 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

- OCaml's lib directory layout changed in 5.0. The unix subdirectory has been
- automatically added to the search path, but you should add -I +unix to the
- command-line to silence this alert (e.g. by adding unix to the list of
- libraries in your dune file, or adding use_unix to your _tags file for
- ocamlbuild, or using -package unix for ocamlfind).
