The number one cause of this is having the interface marked as
"allow-hotplug" instead of "auto" in the interfaces(5) file.
Edit /etc/network/interfaces and see if your interface is defined in
this file at all. (If it's not, then it's being defined some *other*
way, either by Network Manager, or by systemd, or something else).
If you see your interface marked with "allow-hotplug name", change it
to "auto name".
The installer thinks every system is some silly mobile/laptop thing,
so it defaults all ethernet interfaces to "allow-hotplug", even if
the interface is soldered onto the motherboard and is absolutely
not "hot-pluggable". For most desktop or server systems, this will
be the wrong choice. And it causes *exactly* the symptom you're
describing here.
