Comment # 1 on bug 1153849 from Mindaugas Baranauskas

The most confusing situation is in openSUSE Leap 15.1 builds ��� here both 
"Conflicts: otherproviders(%{name}-branding)" and 
"Conflicts: %{name}-branding" produces RPMLIST warnings. This seems to be bug
of same roots.

e.g. in https://build.opensuse.org/package/show/home:embar-:calamares/calamares

> with "Conflicts: otherproviders(%{name}-branding)"
calamares-branding-upstream.noarch: W: suse-branding-missing-conflicts
calamares-branding
Any branding flavor package that provides the generic branding must also
conflict with all other branding packages via conflict on the generic branding
name

> with "Conflicts: %{name}-branding"
calamares-branding-upstream.noarch: W: conflicts-with-provides
calamares-branding
The same symbolic name is provided and conflicted. This package might be
uninstallable, if versioning matches

How to correctly avoid such RPMLINT warnings in openSUSE Leap 15.1 and
Tumbleweed builds?
