Comment # 6 on bug 1200658 from Michael Andres

@Guillaume/Dirk
I pass it to you, hoping you find a way to resole this issue on ARM.

Without arm binary packages in the SLE update repos, they are not usable on
Leap-15.4.arm. But the SLE update repos are included in the arm images (and
maybe proposed to be added to the system elsewhere).

Just a hint:
[https://doc.opensuse.org/projects/libzypp/HEAD/zypp-services.html#services-usecase-4]
I know opensuse - for whatever reason - does not want to offer services (RIS),
but they could be a way to handle those issues. A repoindex.xml for ARM e.g.
could leave the SLE repos disabled or add an additional repo that provides the
missing arm packages.

It would not even be necessary to host such a repoindex.xml on d.o.o. It could
as well be shipped by a package and installed on the local system. This way
changes to the repo set could be distributed by a package update.

  Installed e.g as /Local/Service/repo/repoindex.xml
  the service would be added by 'zypper as -f /Local/Service openSUSE'

If actually maintained by a package, switches like debugenable and sourceenable
in the example should be replaced by repovariables, so the user could maintain
the values in /etc/zypp/vars.d rather than having to edit the repoindex.xml
itself.
