Error: Sub-process /usr/bin/dpkg returned an error code (1)

Turned out it was nprobe. This is on a default debian 12 install, as per official ntopng instructions. You can see what happens, looks like two extra services are doubled, falsely named and do not need to be there. Both ntop and nprobe do not start at boot, even though I enabled systemd services:
