Gang, I'm trying to use YUP to get some stuff but is not working: yum install mod_perl You have enabled checking of packages via GPG keys. This is a good thing. However, you do not have any GPG public keys installed. You need to download the keys for packages you wish to install and install them. You can do that by running the command: rpm --import public.gpg.key For more information contact your distribution or package provider. [[email protected] conf.d]# rpm --import public.gpg.key error: public.gpg.key: import read failed. Any idea how can I make this work?
