Fedora Users — Installing erlang using yum

Hi,

Thank you Roger and Paul for your support .

But i have been trying to use yum but facing problem with it also.

While installing erlang using yum its giving error .

Not only install but update using yum is giving the same error.

Initially it gave an error

# 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

But after making some modifications its now showing the following error

#yum install erlang
Loading "installonlyn" plugin
Setting up Install Process
Setting up repositories
core [1/3]

Can you suggest something like what should be done in this case . I am a new user to Fedora.

Thanks & Regards,
