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.

ezcurl.0.3 is not installed. Install it? [Y/n] y
The following actions will be performed:
=== install 5 packages
  - install conf-libcurl 2            [required by ocurl]
  - install dune         3.21.0       [required by ezcurl]
  - install ezcurl       0.3 (pinned)
  - install ocamlfind    1.9.8        [required by ocurl]
  - install ocurl        0.9.2        [required by ezcurl]

The following system packages will first need to be installed:
    libcurl-devel openssl-devel

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

opam believes some required external dependencies are missing. opam can:
> 1. Run yum to install them (may need root/sudo access)
  2. Display the recommended yum 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
