Did an FC4 to FC5. Software Updater gives me this Message "Unable to retrieve Update Information". Tried both Yum and Yumex, both failed. I was hoping I could get by with an update vs new install. Any help appreciated.
Most mirrors is very busy, because of a lot of people, downloading FC5 isos.
just try again & again til you hit a reponding mirror.
In yumex you can just press the 'refresh' button again and again until you hit a responding mirror.
You can also set the timeout & retries in yum.conf something bigger than default (see 'man yum.conf' for more info).
