Just in case people haven't bottomed out all the threads in which this is mentioned, the Fedora Core 1 yum (+ up2date) repositories shipped with FC1 are not working. This is most likely due to a web server misconfiguration on fedora.redhat.com. So you will get "File not found" errors when using the RHN applet, up2date, and/or yum. You can do one of two things: 1) EASIEST: wait until the problem is fixed (see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=110194). You can do this if you don't want to install any new software in the next 24 hours (or however long it takes to fix the problem). YOu can ignore any errors. 2) SLIGHTLY HARDER: change your /etc/yum.conf and /etc/sysconfig/rhn/sources.list to these two files temporarily: http://www.xades.com/proj/yum.conf.bugfix http://www.xades.com/proj/sources.bugfix Of course, you can also perform substitutions by hand to your /etc/yum.conf and sources.list files; check out the above two links for examples.
