Setting up UCS Repository when no Internet access

Hi, I’m setting up UCS in a closed network without any Internet access. I’ve installed a standard UCS and thought I’d also install a local repository on that server. Unfortunately when running univention-repository-create I’m getting an error saying that it failed to install univention-debmirror.

I’ve mounted UCS-4.4-installation-amd64.iso as /mnt and try to run univention-reposirtory-create -N -m /mnt
but the missing univention-debmirror seems to not be available. I assume that is because it tries to install it from Univention online repository.

Any suggestions as how to get past this would be most welcome :grinning:
