Hi, all. I'm experiencing a problem with Yum. When I call 'sudo yum update' it tells me that it can't find any mirrors & after doing a 'sudo yum clean all' it just informs me it can't find any base repo & quits. This is on a brand new installation of CentOS 6.2 x86_64. I suffered the same problem with Fedora 19 too. I have several Ubuntu & Mac OS X machines that suffer no network connection problems & I can connect to the InterWeb just fine (via two HP Procurve 2426s). Any help appreciated. Cheers, Phil...
