Greetings: On a test server, I tried to have yum update zlib-devel, and ran into the problem below. yum update zlib-devel Gathering package information from servers Getting headers from: Red Hat Linux 7.3 base Getting headers from: Fedora Legacy tools for Red Hat Linux 7.3 Getting headers from: Red Hat Linux 7.3 updates Finding updated packages Downloading needed headers Resolving dependencies .Dependencies resolved I will do the following: [update: zlib-devel.i386] I will install/upgrade these to satisfy the dependencies: [deps: zlib.i386] Is this ok [y/N]: y Getting zlib-devel-1.1.4-8.7x.i386.rpm Error: GPG Signature check failed for /var/cache/yum/updates/packages/zlib-devel-1.1.4-8.7x.i386.rpm You may want to run yum clean or remove the file: /var/cache/yum/updates/packages/zlib-devel-1.1.4-8.7x.i386.rpm You may also want to check to make sure you have the right gpg keys Exiting. How do I verify we have the right gpg keys? And if I have the wrong keys, how do I get the right keys? Thank you.
