I built debian local mirror repository.And add this local mirror url into the create host job.After click create host, on the path /srv/tftp/boot, there are two files linux and intrid.The file size of them are zero.Then, I changed the mirror to the debian official mirror. It worked.But, the unattened installation has been processing on a physical machine.This machine has been signed IP addr from foreman server.This IP is a 192.168.1. IP address, it can’t connect to the debian offical site. So, when downloading debconf preconfiguration file, it always failed.I don’t know how to solve this problem?
So, it because of debian mirror problem?
