[oe] do_rootfs failing with gpgkey error

[Srinivasa Rao Ragolu]

Hi Friends,
                  I have been working on a linux platform and mips 
processor. I am using openembedded to prepare rootfs and SDK. Till now 
for every package .ipk files are getting created. Now Its necessary to 
me to move from .ipk to .rpm. so I modified the following stanzas in distro

                  INHERIT += "package_rpm"
                 PREFERRED_PKG_FORMAT ?= "rpm"
# If we're using an .ipk based rootfs, we want to have opkg-nogpg 
installed so postinst script can run
IPKG_VARIANT = "opkg-nogpg" (/kept as it is for .rpm/)

                      Now I could able to build all the packages as 
.rpms successfully but in the final task do_rootfs failing with 
following errors...

| You have enabled checking of packages via GPG keys. This is a good thing.
| However, you do not have any GPG public keys installed. You need to download
| the keys for packages you wish to install and install them.
| You can do that by running the command:
|     rpm --import public.gpg.key
|
|
| Alternatively you can specify the url to the key you would like to use
| for a repository in the 'gpgkey' option in a repository section and yum
| will install it for you.
|
| For more information contact your distribution or package provider.

                              *  I have tried so many things to resolve this issue. Could you please suggest me, How to disable gpg keys and build rootfs successfully.....
