Newbie's quuestion: RPM package not signed
I installed several packages (include Adobe Flash Player) in Fedora 9 using yum install command, and always failed since these packages are not signed.
Searching internet I found that I should some 'key', but did not find useful instruction on how to do this.
Anyone can tell me use what key shall I import, import to where? How to do this? Thanks a lot for your guide.
