I am trying to install Varnish on CentOS 5.5 using command yum install varnish, but the installation procedure can't be completed because of this warning message:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID ...... Public key for libedit-20090923-3.0_1.el5.rf.x86_64.rpm is not installed

How do I solve this problem?


It looks like you're trying to install a RepoForge RPM without having the GPG keys installed, you can either install the keys by using this site:


Or you can tell yum to ignore keys with the --nogpgcheck option. This should only be done for packages that came from a known, trusted source!

  • Thank you i used the rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt command to install the key and then i tried to install varnish and the installation completed successfully – Muhamad Bhaa Asfour Apr 17 '12 at 12:42
