I'm trying to install the driver for an HP Colour Laserjet 3500 in CentOS 5. I've installed the kde.repo (with appropriate priorities set up), but when I try yum install pxljr-1.1-1.i386.rpm, I get the above message that 'the package is not signed'. I've previously tried running yum localinstall on the downloaded package with the same result. How do I resolve this please?
