EDIT:
I have created an even smaller image for the XU3/4-based boards than the official minimal image.
It's a 280MB archive, with a ~600MB rootfs, based on Ubuntu Base and with minimal tools installed:
to connect to ethernet, to connect to wifi with nmtui, screen, ssh, manpages, vim, mc, wget, curl.
It has the odroid official repository added and the official kernel installed, so it can be updated as usual.
It resizes partition and regenerates ssh keys on first boot.

Just a suggestion for the Ubuntu minimal release: try and base the image off Ubuntu Base (http://cdimage.ubuntu.com/ubuntu-base/releases/)
It's much more lightweight and minimal...
Just install a few networking tools (like wpa_supplicant, dhclient) on it.
I was surprised to get the ubuntu minimal and see it did not have ifconfig installed to configure the network, but it had ModemManger installed and running (?!).
And there were lots of useless packages, like adwaita-icons, or libwayland
