Warning:usbview-1.0-1.src.rpm:v3dsasignature:nokey,key idab42a60e

This line of code indicates that the installation failed because the appropriate key was not installed on your system to verify the signature. For this package to pass the checksum, you can do so by importing the public key of Red hat, in particular by running the following command under the shell:

#rpm-import/usr/share/rhn/rpm-gpg-key (note case)
