Bug 1403439

Description of problem:

I'm getting the following error while trying to create a CentOS 7 container in a Fedora 25 Workstation:

# lxc-create -n centos72-mitaka -t centos
Host CPE ID from /etc/os-release: cpe:/o:fedoraproject:fedora:25
This is not a CentOS or Redhat host and release is missing, defaulting to 6 use -R|--release to specify release

Redirecting to '/usr/bin/dnf --installroot /var/cache/lxc/centos/x86_64/6/partial -y --nogpgcheck install yum initscripts passwd rsyslog vim-minimal openssh-server openssh-clients dhclient chkconfig rootfiles policycoreutils' (see 'man yum2dnf')

Error: Failed to synchronize cache for repo 'fedora'

If I try to use the template directly:
