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.

unionFind.20260226 is not installed. Install it? [Y/n] y
* No agreement on the version of ocaml:
- (invariant) -> ocaml-base-compiler = 4.14.2 -> ocaml = 4.14.2
- unionFind >= 20260226 -> ocaml >= 5.4.0
You can temporarily relax the switch invariant with `--update-invariant'
