Alle, Sorry if this shows up as a repost. So, I try to test my yum installation (from download.fedoralegacy.org) by installing xtraceroute and get the following: [root@hilo etc]# yum install xtraceroute 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: Fedora Legacy Project RHL 7.3 Legacy Utilities Getting headers from: Red Hat Linux 7.3 updates Finding updated packages Downloading needed headers Resolving dependencies .Dependencies resolved I will do the following: [install: xtraceroute.i386] I will install/upgrade these to satisfy the dependencies: [deps: gtkglarea.i386] Is this ok [y/N]: y Getting gtkglarea-1.2.2-10.i386.rpm Error: GPG Signature check failed for /var/cache/yum/base/packages/gtkglarea-1.2.2-10.i386.rpm You may want to run yum clean or remove the file: /var/cache/yum/base/packages/gtkglarea-1.2.2-10.i386.rpm You may also want to check to make sure you have the right gpg keys Exiting. [root@hilo etc]# I ran a yum clean all and yum clean headers and tried again with no joy. I assumed (wrongly, obviously) that the keys were installed with yum. I perused the website and saw nothing regarding keys, nor did I find anything when I searched through the list. Obviously, I've missed something. Any help would be appreciated.
