yum: public key not available
I am quite a newbie with package management:
To follow the guidelines furnished by the site of fedora, I made a yum update, to begin with. What a surprise when, at the end (after like 7 hours of download), I found messages like:
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 4f2a6fd2
public key not available for //var/cache/yum/updates-released/packages/yum-2.2.2-0.fc3.noarch.rpm
What does that mean, does this mean there is a problem, and what can I do to clear it?
