Couldn't open file /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle error while installing Pre-install RPM

Hi,

OS : RHEL 7,5 64-bit
Preinstall RPM : OEL 7

I got this error while installing Pre-install RPM . I have shared the steps in this post to fix the same. This fix worked perfectly for me and i never publish a fix unless i tested it.

Error :

GPG key retrieval failed: [Errno 14] curl#37 - "Couldn't open file /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle"

Reason :

GPG key is missing.

Solution :

Download the GPG key.

[root@***** ~]# wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
