'Package otopi-java-1.3.1-0.0.master.20141124.git523a28c.el6.noarch.rpm is not signed' when trying to install 3.6 from ovirt-master-snapshot

Hello, I'm running 'yum install ovirt-engine' from ovirt-master-snapshot for ovirt 3.6 , and from ovirt-master-snapshot-static. this the second time i do it this week and in first time i didn't had this issue, but this time, I'm getting this "Package otopi-java-1.3.1-0.0.master.20141124.git523a28c.el6.noarch.rpm is not signed" this message appears only after finished downloading all packages and installation is dropped. This is a clean installation and i don't have any 'gpgchk enabled' Best regards, -- Michael Burman Intern in RedHat Israel, RHEV-M QE Network Team Mobile: 054-5355725 IRC: mburman
