Yum:restoring default repositories

	Note:
	If you have problems with your yum setup you may have entered incorrect repository values. Remove the current values and restore the original setting with these commands

cd /home/e-smith/db/
mv yum_repositories yum_repositories.po
/etc/e-smith/events/actions/initialize-default-databases

Now you have a clean install, you can re-add 3rd party repos as described above

signal-event yum-modify

and check if you can update your server

yum update
