MORE YUM HEADACHES!!!!!!!

[Mirco Scarmaucci]

Yum has been working quite fine lately on installing new sofware and
updates but out of the blue after a complete upgrade thru synaptic yum
begun producing the following output:

[root at localhost mirco]# yum update

Cannot find a valid baseurl for repo: [[['release', 'updates-testing'
Error: Cannot find a valid baseurl for repo: [[['release',
'updates-testing'


 I am not aware of the existence of the repo [[['release , @'updates
testing'
How did it get inserted into my yum.conf?
The upgrade thru synaptic did not update any yum.conf file or likes.
What has happened?

Any help or idea?
