The local host has been modified to use this local repository. Other hosts

ucr set repository/online/server="%(hostname)s.%(domainname)s"

set this variable on all hosts using this repository server. For example:

--set name="%(hostname)s repository" \
--set repositoryServer="%(hostname)s.%(domainname)s"
