I'm quite frustrated here. I have three i386 systems, and am helping a friend with his x86_64. With FC1, I modified my /etc/sysconfig/rhn/sources file to allow for mirrors, and everything worked well. But now I am using FC2. When FC2 came out there was a notice that the modifying of sources files was not strictly necessary, since up2date would go through a round-robin procedure to find an available server. For the i386 system, up2date seems to work. I have no trouble upgrading it. For the x86_64 system though, u2date no longer seems to work. It worked since June, but not anymore. No matter which server it is looking at, it seems to hang. I tried yum update also, but it also does nothing. Should I just edit the sources file, or are the servers having a bad week?
