trouoble with "yum update" after updating FC4->FC5

[Joachim Backes [RHRK]]

Hi,

needing help after having updated FC4 -> FC5:

Doing the first "yum update" after the first reboot into FC5 says:

yum update
Loading "installonlyn" plugin
Setting up Update Process
Setting up repositories
core                                                                 [1/3]
Cannot find a valid baseurl for repo: core
Error: Cannot find a valid baseurl for repo: core

Re-installing fedora-release did not help.
Is there any possibility to setup yum correctly?

Regards
