I have now managed to get both yum and rhn working, although rhn doesn't give me nowhere near the updates avaliable that yum does.
I still have a problem though, when I try to run yum install I'm getting the following errors
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 8d f56d05
Error: Could not find the GPG Key necessary to validate pkg /v ar/cache/yum/fedora-extras/packages/wxGTK2-2.4.2-0.fdr.1.1.i38 6.rpm
Error: You may want to run yum clean or remove the file:
Error: You may also check that you have the correct GPG keys i nstalled
Although I have been to the livna.org site and run the following when logged in as root in a terminal window.
rpm --import http://rpm.livna.org/RPM-LIVNA-GPG-KEY
And I got no errors when I ran the command.
Can anyone shed any light ??
