Hi to all -
I'm upgrading a cobbler server running cobbler 2.0.11 on CentOS 6.0, installing fresh on a new machine running RedHat 6.1and cobbler 2.2.3. The new install (cobbler from EPEL RPMs) is uneventful, "cobbler check" indicates nothing suspicious-looking.

After initial configuration and check that cobblerd and httpd start-up OK, I thought I would take the wiki recommendation and attempt a "cobbler replicate". Verified rsync connectivity between the hosts. Result is the "internal error" below. Wondering if I've missed something simple. Thanks......Nick Geo
