[Spacewalk-list] Problem on first installation

[Carlo Filippetto]

Hi all,
I'm new with Spacewalk.
I'm able to install and make the first configuration on Centos 5.7,
and version Spacewalk 1.6 + Postgress

I follow these guides:
https://fedorahosted.org/spacewalk/wiki/UserDocs#Introduction
http://wiki.centos.org/HowTos/PackageManagement/Spacewalk#head-e04eadc5ed664bd79068564af7d84662c3081b22



Now I'm tring to add channel but I receive always the same error when
try to use

spacewalk-repo-sync

-----------------------------
/usr/bin/spacewalk-repo-sync --channel centos5-updates-i386 \
>                              --url http://mirror.centos.org/centos/5/updates/i386/ \

If I reboot the service I receive:
