Some pretty newbie questions I'm afraid, but I *have* read the Howto and searched Google in vain. I'm running Fedora Core 1. I have a single co-lo server. I updated to Fedora using apt, but now I'm wondering whether to stick with apt or use yum. I don't want to keep upgrading Fedora to the latest release; security updates are what concern me most from now on. Firstly, what are yum's advantages over apt, apart from coming with a useful cron script? Secondly, my yum.conf has the lines: [core] name=Fedora Core $releasever - $basearch - Base baseurl=http://fedora.redhat.com/releases/fedora-core-$releasever The thing is, if I run "yum info", I get: Gathering header information file(s) from server(s) Server: Fedora Core Null - i386 - Base retrygrab() failed for: http://fedora.redhat.com/releases/fedora-core-Null/headers/header.info In other words, $basearch is getting set but $releasever isn't. Again, apologies for the dumb questions.
