There is still an Ubuntu machine running here, 24.04.LTS
Turned out, Ubuntu has another super-annoying new “feature”:
Ubuntu Server systemd waits almost indefinitely until it can phone home at boot. Note that this is even without having that “Pro” thing!
Please, what is the recommended method to turn off this behaviour, and let the system just start, no matter whether it can phone out somewhere or not?
This machine is intended as a purely local server without internet connection. So there is no need to preserve anything of Ubuntu special features like snap, unattended updates etc, which might make things easier.
