Migration SLES4SAP 15SP7 to 16 - problem with product definition

[angelabriel]

Starting with a SLES4SAP 15SP7 installation and following the description in https://confluence.suse.com/display/SLES16/SLES+16+Migration section 'Testing'.
zypper in suse-migration-sle16-activation
failed with

Problem: 1: nichts stellt 'product(SLES) >= 15.6' bereit, das vom zu installierenden suse-migration-sle16-activation-2.1.13-150700.1.1.noarch benötigt wird
 Lösung 1: suse-migration-sle16-activation-2.1.13-150700.1.1.noarch nicht installieren
 Lösung 2: suse-migration-sle16-activation-2.1.13-150700.1.1.noarch durch Ignorieren einiger Abhängigkeiten brechen

It seems the problem is that on SLES4SAP the SLES_SAP-release package is installed but on plain SLES sles-release.
And the SLES_SAP-release package does not provide product() = SLES but product() = SLES_SAP
Whereas e.g. the provide product(SUSE_SLE) = 15.7 is available in both packages

# rpm -q --provides SLES_SAP-release | more
SLES_SAP-release = 15.7-150700.28.1
SLES_SAP-release(x86-64) = 15.7-150700.28.1
SLES_SAP-release-15.7

yes it's because the package has

Requires:         product(SLES) >= %{MinSLEVersion}

in its spec file. So you are saying this is not suitable ? We had the same for 12-15 migration and that worked also on SLES4SAP. I guess something has changed in the product definition.

FYI - PM asked for a tracking bug, so we now have https://bugzilla.suse.com/show_bug.cgi?id=1247775

Problem: 1: nothing provides 'product(SLES) >= 15.6' needed by the to be installed suse-migration-sle16-activation-2.1.13-150700.1.1.noarch
 Solution 1: do not install suse-migration-sle16-activation-2.1.13-150700.1.1.noarch
 Solution 2: break suse-migration-sle16-activation-2.1.13-150700.1.1.noarch by ignoring some of its dependencies

Choose from above solutions by number or cancel [1/2/c/d/?] (c):

The following packages needs to be adapted to handle this properly

./image/package/suse-migration-rpm/image.spec.in:Requires:       product(SLES) >= %{MinSLEVersion}
./package/suse-migration-sle15-activation-spec-template:Requires:         product(SLES) >= %{MinSLEVersion}
./package/suse-migration-sle16-activation-spec-template:Requires:         " >= %{MinSLEVersion}

I'm not sure if we can require something like "product(SLES) or product(SLES_SAP)" probably not

[schaefi]

I'll take this one
