Opam-2.0.0: how to list all available switches?

Learning
1

My opam version is 2.0.0~beta5.
I don’t know how to install ocaml-4.02.0 with this opam version.

opam switch list-available

doesn’t list anything…
In the past

opam switch 4.02.0

would have done the job.
I have those repositories:

# opam repo
[NOTE] These are the repositories in use by the current switch. Use '--all' to
       see all configured repositories.

opam switch list-available works for me (I’m on rc2, but beta5 worked as well). I usually use opam switch list-available base though so that it listed the base compiler versions.

Ok, I destroyed ~/.opam and did an opam init to fix the problem.

Can you show the output of ‘opam repo’?
It still does not work for me.
opam switch -a was working well in previous opam versions…

I don’t change anything on opam repo.

$ opam repo
[NOTE] These are the repositories in use by the current switch. Use '--all' to see all
       configured repositories.

<><> Repository configuration for switch default ><><><><><><><><><><><><><><><>

$ opam repo --all

I confirm that for me, with 2.0.0~beta5 on Debian, it does not work
