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?
