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 development version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.1, which can't be reverted.
You may want to back it up before going further.
