The following are potential configuration items that you may want to fix:

1: The 'server' field in /etc/cobbler/settings.yaml must be set to something other than localhost, or automatic installation features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2: For PXE to be functional, the 'next_server_v4' field in /etc/cobbler/settings.yaml must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3: For PXE to be functional, the 'next_server_v6' field in /etc/cobbler/settings.yaml must be set to something other than ::1, and should match the IP of the boot server on the PXE network.
4: some network boot-loaders are missing from /var/lib/cobbler/loaders. If you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, andmenu.c32.
5: debmirror package is not installed, it will be required to manage debian deployments and repositories
6: The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings.yaml) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one

Restart cobblerd and then run 'cobbler sync' to apply changes.
