Not all Requires for OpenSUSE had an equivalent Fedoroa Requires
Requires for OpenSUSE from jpackage
Requires: glibc, libX11-6, libXau6, libXext6, libXi6, libXrender1,
libXtst6, libasound2, libxcb1, libz1
Requires for Fedora from jpackage:
Requires: glibc, libX11, libXau, libXext, libXi, libXrender, libXtst,
The RPM spec for Fedora does not get any Requires with libasound and libz.

Yes of course, if it has Requires and the Requires is not present, that is
the problem we now got on Fedora for the installer built in OpenSUSE.
However, if I omit all these Requires, then RPM will install/unpackage the
application just fine. What you are saying if any of these Requires is not
present then the install/unpack of the RPM will fail?
So these Requires are only necessary for the RPM installation process?
We previously uses jpackager, and did not specify these Requires when
building the installer. Installation worked fine though on both OpenSUSE
and Fedore. Probably because these Requires where installed as default on
