Bryan,
I hope my comments about information gathering were not taken personally. I did not mean to be accusatory or anything. I appreciate the advice you were giving, and merely offering an opinion how maybe your wealth of knowledge could be made more accessible to a newbie such as myself.
Something else is using the RPM database. It's just preventing multiple write access. Do you have up2date running?
Yes, that turned out to be the case. Thanks for suggesting this. The up2date icon was indicating something needed to be downloaded. So I went through the up2date process and completed it, and then re-ran the public key install, and it worked. I now have also successfully installed Xine.
Okay, now I'm over that obstacle, now I am curious. Why did Fedora seem to be able to install things through yum immediately after install, and CentOS had to do this key installation stuff?
Dave
